Story at-a-glance
- Myalgic encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS), affects 2 million Americans with debilitating fatigue, post-exertional malaise, and cognitive problems. New research links this condition to mitochondrial dysfunction and impaired cellular energy production
- Studies show ME/CFS patients struggle to produce adequate energy through normal pathways
- The condition compromises immune function by reducing natural killer (NK) cells and dendritic cells, leaving the body with diminished defense capabilities and increased vulnerability
- Blood vessel function suffers when cellular energy drops, causing circulatory problems like poor oxygen delivery, dizziness, and cold extremities that worsen overall fatigue
- Recommended strategies include reducing seed oil consumption, supporting gut health with whole foods, exercising to generate new mitochondria, and prioritizing restorative sleep
Americans report high rates of chronic fatigue, but myalgic encephalomyelitis (ME), also called chronic fatigue syndrome (CFS), represents a distinct, clinically defined disease that affects a small subset of the population rather than a diagnosis that explains widespread tiredness. Around 2 million people currently have ME/CFS, which is characterized by crushing fatigue that does not improve with rest, plus post-exertional malaise, unrefreshing sleep, pain, and cognitive problems, such as brain fog.1
The exact cause of ME/CFS remains unknown. Research suggests that the condition can follow certain triggers, including acute viral infections and severe physical or psychological stress, but no single cause has been identified. In recent years, several studies have reported abnormalities in mitochondrial function and energy metabolism in people with ME/CFS, suggesting a possible role for disrupted ATP production.
Immune Cells Show Clear Signs of Energy Overload
A study published in Cell Reports Medicine examined how ME/CFS is linked to a failure in cellular energy production. For the analysis, the researchers looked at an array of biomarkers, including immune cell metabolism, immune cell composition, and blood makeup.2
The study population included 61 individuals who met strict diagnostic criteria for ME/CFS, meaning they had long-standing fatigue, profound crashes following physical or mental effort, unrefreshing sleep, and cognitive problems.
• There is an ATP imbalance — The study found that adenosine monophosphate (AMP) and adenosine diphosphate (ADP) — two forms of energy molecules that rise when the cell exhausts adenosine triphosphate (ATP) — were elevated in ME/CFS patients. To put that into perspective, ATP is your body’s ideal energy format, whereas ADP and AMP are the substrates for ATP synthesis. If your body begins to use these, the energy you’re using is substandard.
• A theory on how cellular energy production is compromised — The researchers believe that those with ME/CFS have trouble producing enough energy due to an obstacle in the production chain. While their findings aren’t solid enough to propose a definite conclusion, here’s what they theorized:3
“The elevated NAD+ [nicotinamide adenine dinucleotide] levels observed in PBMCs [peripheral blood mononuclear cells], together with the increased AMP and ADP, suggest that NAD+ is not being efficiently reduced to NADH [nicotinamide adenine dinucleotide + hydrogen] to drive ATP synthesis through oxidative phosphorylation.
This impaired reduction of NAD+ to NADH may also help explain the observed inverse correlation between plasma AMP and PBMC ATP levels, although this finding requires further study.”
• Another major finding involved the natural killer (NK) cells — The researchers also discovered changes in the balance of immune cell types, including a reduction in certain mature dendritic cells and terminal NK cells. These normally help coordinate immune responses and act as a first line of defense.
When the population of NK cells drops, the immune system loses some of its agility and responsiveness. This means the fatigue you’re feeling is not only about energy loss — your immune system shifts into a pattern that reflects reduced readiness.
• Blood tests paint a more complete picture — The team reported higher levels of proteins associated with thrombus formation and altered vascular reactivity in the ME/CFS group. For context, thrombus means blood clot formation, and vascular reactivity reflects how blood vessels respond to signals that regulate tightening and relaxation.
When these protein levels rise, it suggests the lining of the blood vessels is under strain, which disrupts healthy circulation. For someone with ME/CFS, that could mean poor oxygen delivery, dizziness upon standing, and cold extremities.
• The study highlighted where the largest metabolic imbalances appeared — Individuals with the most altered ATP-to-ADP ratios tended to show larger distortions in immune cell composition. That suggests a link between energy depletion and immune exhaustion. If the immune system lacks energy, its cells lose the ability to mature properly or carry out normal defense tasks.
In addition, the vascular protein shifts closely aligned with the energy imbalance. When cellular energy drops, blood vessel function suffers. When this happens, the delivery of nutrients and oxygen is affected. This creates a loop that leaves the entire body underpowered.
• The biological mechanisms behind these findings trace back to disrupted ATP production — Normally, mitochondria generate ATP through oxidative phosphorylation, a process that depends on oxygen, nutrients, and intact cellular machinery.
When ATP falls and ADP or AMP rises, the cell enters a state of metabolic stress. Here, the cell may shift into emergency survival mode instead of normal function. That shift drains resilience, reduces cellular performance, and leaves tissues — especially the immune system and blood vessels — operating at a deficit.
• Another mechanism involves immune maturation — Dendritic cells and NK cells rely on ATP to fuel activation, communication, and response signaling. When ATP drops, these cells lose their functional sharpness. The study found this exact pattern: fewer mature cells and more signs of immune imbalance.
• Mechanistic hallmarks of ME/CFS — Although the paper did not measure symptom improvement over time, it did compare variables to determine which markers best distinguished ME/CFS participants from healthy controls.
A statistical model that incorporated metabolic markers, immune shifts, and vascular proteins reliably separated the two groups. This includes an abundance of AMP and ADP. In addition, the immune system is skewed towards less mature pathogenic fighters, alongside a lower population of NK cells.
Energy Deficits Push the Immune System Toward Burnout
In a related study published in Biomolecules, researchers showed how energy metabolism and immune function interact in ways that worsen symptoms of ME/CFS over time. Here, they used a broad body of evidence to map out how energy shortages inside cells feed directly into immune dysfunction, especially immune senescence and immune exhaustion.4
• Mitochondrial dysfunction stands at the center of this illness — However, the study adds something new to the conversation. In particular, the researchers noted that those with ME/CFS have compromised levels of carnitine, which is needed for fatty acid oxidation and energy metabolism.
Moreover, the researchers noted that this chemical helps maintain integrity of the mitochondria and reduce the production of reactive oxygen species (ROS). The image below provides an overview of their hypothesis:
Source: • The link to viruses — The paper identifies striking parallels between ME/CFS and chronic viral infections. In chronic viral states, the immune system fights for long periods without rest. Over time, some immune cells lose function and responsiveness through a process called cellular senescence, a state in which cells remain alive but no longer divide or respond effectively to threats. And when this reaches a chronic state, ME/CFS pathology occurs.
• Immune function breaks down — The immune system in people with ME/CFS shifts into a dysfunctional state. Similar to the previous study, they have altered NK cell function, changes in cytotoxic T cells, and persistent immune activation patterns that resemble those seen with unresolved infections.
• How energy metabolism and immune regulation are linked — The researchers argue that mitochondrial defects impair the immune system’s internal communication network. In addition, the same dysfunction creates a bottleneck for immune activity itself. In other words, your cells do not produce enough energy to meet the demands of immune signaling, repair, or defense.
• ME/CFS displays patterns of metabolic inflexibility — Cells struggle to switch between energy pathways or ramp up ATP production during stress. When your cells cannot adapt, even minor activity can produce a disproportionate crash. The featured study highlights published literature showing impaired energy production and utilization.
• Immune exhaustion driven by chronic metabolic strain — The paper explains that persistent energy deficits interfere with immune cell communication and their ability to generate powerful responses. When immune cells lack ATP, they lose the ability to proliferate, secrete cytokines, or kill infected targets effectively.
Strategies to Reclaim Your Energy and Live Life to the Fullest
If you’re low on energy, the solution isn’t drinking more coffee or energy drinks. It lies in your mitochondria, which has been compromised to such a point that it can’t function properly anymore. That said, I’ll be releasing a new book soon, “Cancer Cure,” which explores what changes occurred in our society today that resulted in a dramatic rise in metabolic dysfunction among millions of Americans.
The book will also discuss several strategies that can help you regain your cellular energy and improve your quality of life. Here are some of my recommendations:
1. Reduce linoleic acid (LA) intake — One of the reasons why you’re feeling fatigued is excess intake of LA, one of the most prominent toxins in the Western food supply. In fact, I’d go so far as to rank it above refined sugar, although that plays a role, too.
The reason why I’m saying this is because excess LA generates reactive byproducts that eventually suppress immune behavior, as well as damaging your mitochondria. So, get rid of any foods you have that contain LA, which are mainly seed oils — soybean, corn, cottonseed, canola, sunflower, and grapeseed.
In a previous article, I mentioned that modern Western diets now contain 15 to 25 grams of LA daily, which is a far cry from the estimated 2 to 4 grams that pre-industrial populations consumed.
In light of this, I recommend you keep your LA intake below 5 grams a day; if you can keep it below 2 grams, that’s even better. To track the LA in your food, sign up for the upcoming Mercola Health Coach app. It contains a feature called the Seed Oil Sleuth, which calculates daily LA consumption to a tenth of a gram. Swap LA-rich seed oils for healthier saturated fats like grass fed butter, ghee, tallow, and coconut oil.
2. Familiarize yourself about sources of LA — You’ll find LA not just in cooking oil sold in grocery stores. They’re found in most ultraprocessed foods, so it’s important to read through the ingredient list of whatever you’re buying.
In addition, it would be wise to minimize the times you eat in restaurants or order takeout. Unless strictly stated otherwise, it’s safe to assume that all the food cooked in these establishments use seed oils.
LA also is found in conventionally raised chicken and pork due to the ultraprocessed nature of their feed. Prioritize beef, lamb, bison, and other ruminants, which are likely to have lower LA levels.
3. Support your immune cells at the mitochondrial level — When ATP runs low, immune cells can’t communicate, divide, or kill threats efficiently. Several natural compounds have shown promising effects in boosting mitochondrial resilience and NK cell performance:
• Beta-glucans from yeast and mushrooms wake up your immune system by activating macrophages and NK cells.
• PQQ, found in papaya and green tea, sparks the production of new mitochondria and protects them from oxidative wear and tear.
• Urolithin A, a gut-derived compound from pomegranates, recycles defective mitochondria to keep your cellular engines running clean.
• Polyphenols like quercetin, fisetin, curcumin, and resveratrol scavenge harmful free radicals and reduce inflammatory suppression of NK cells.
In preclinical studies, when NK cells were given a combination of these compounds — delivered via nanoliposomes that targeted mitochondria directly—their killing capacity jumped five to tenfold. Instead of exhausting after five to ten kills, these cells could eliminate 30 to 50 targets before tiring out.
4. Repair your gut — Aside from your mitochondria, LA also wrecks your gut microbiome, which plays an extensive role in your health, including energy metabolism.5
Gut repair requires adequate carbohydrate intake to support intestinal cells and microbial balance. Your gut lining relies on glucose as a primary fuel, and insufficient carbohydrate intake can slow repair and weaken barrier integrity. Most adults need at least 250 grams of carbohydrates per day, adjusted for activity level and metabolic status. This intake supports gut repair, thyroid signaling, and overall energy balance.
Begin with well-tolerated carbohydrate sources such as sweet potatoes, carrots, winter squash, ripe fruit, and cooked white rice. These foods supply glucose while being lower in fermentable substrates. Add high-fiber foods slowly if gut health remains poor. Large amounts of fiber can intensify bloating, cramping, and constipation when intestinal permeability or dysbiosis persists. In this phase, prioritize digestible carbohydrates first and increase fiber only in small, gradual steps as tolerance improves.
As epithelial integrity strengthens and immune signaling stabilizes, fiber tolerance will improve as well. At that point, a broader range of fiber-rich foods can support short-chain fatty acid production and long-term resilience.
5. Exercise with restraint and precision — Your immune system relies on cytotoxic T lymphocytes and NK cells to remove damaged or dysfunctional cells. In ME/CFS, immune signaling, mitochondrial output, and energy recovery all falter, which changes how your body responds to physical stress. So, conventional exercise advice does not apply here.
High-intensity or endurance exercise often worsens symptoms and can trigger post-exertional malaise, a hallmark feature of ME/CFS. Rather than restoring immune function, excessive exertion can deepen mitochondrial injury and prolong recovery.
The goal is not fitness training. The goal is cellular signaling without metabolic overload. Most ME/CFS researchers emphasize gentle, low-stress movement that respects your available energy. Appropriate options include slow walking, light stretching, yoga, tai chi, and short bouts of resistance exercise that use body weight or very light loads.
Time and intensity matter more than duration. Many patients tolerate exercise best in intervals lasting seconds to a few minutes, followed by full recovery. Heart-rate monitoring and pacing strategies help you stay below your anaerobic threshold, which lowers the risk of symptom relapse. As mitochondrial function and autonomic balance improve, capacity often expands gradually.
Progress depends on consistency, recovery, and restraint, not intensity. Any program should adapt to daily energy limits rather than fixed schedules or goals.
6. Get restorative sleep — This is another cornerstone of health that’s often overlooked. In the case of people diagnosed with ME/CFS, research shows that sleep habits are often compromised — longer sleep onset latency and reduced sleep efficiency are common occurrences.6
When you get proper sleep, your body undergoes crucial repair processes. In particular, sleep allows your immune system to rest, allowing optimal surveillance in the long run against wayward cells that contribute to fatigue.
If you’re having a hard time sleeping, there are many strategies to help you. Read “Sleep — Why You Need It and 50 Ways to Improve It.” There, I also go over the science on what happens to your body while you rest, as well as the consequences of insufficient sleep.
Frequently Asked Questions (FAQs) About Chronic Fatigue Syndrome and Mitochondrial Function
Q: What is ME/CFS, and how common is it?
A: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) affects approximately 2 million Americans. It’s characterized by crushing fatigue that doesn’t improve with rest, post-exertional malaise, unrefreshing sleep, pain, and cognitive problems like brain fog.
Q: What does new research reveal about the underlying cause of ME/CFS?
A: Research found that ME/CFS patients have elevated adenosine monophosphate (AMP) and adenosine diphosphate (ADP) — energy molecules that accumulate when cells exhaust their primary energy source, adenosine triphosphate (ATP) — suggesting the body struggles to produce adequate cellular energy.
Q: How does ME/CFS affect the immune system?
A: Patients have reduced populations of natural killer (NK) cells and dendritic cells, both critical for immune defense. Because immune cells depend on ATP to function, energy deficits cause immune exhaustion and reduced ability to fight infections.
Q: Why do ME/CFS patients often experience circulatory symptoms like dizziness and cold extremities?
A: Studies found elevated proteins associated with blood clot formation and altered vascular function. When cellular energy drops, blood vessel function suffers, impairing oxygen and nutrient delivery throughout the body.
Q: What lifestyle strategies may help improve cellular energy production?
A: Recommendations include reducing linoleic acid intake (found in seed oils) to below 5 grams daily, optimizing gut health with fiber-rich whole foods, exercising according to ability to stimulate new mitochondria production, prioritizing restorative sleep, and supporting your immune cells at the mitochondrial level with natural compounds such as beta-glucans, PQQ, urolithin A, and polyphenols.
Newly Discovered Coffee Compounds Outperform Diabetes Drug

Analysis by Dr. Joseph Mercola March 06, 2026
Story at-a-glance
- Scientists identified six previously unknown compounds in roasted Arabica coffee beans, and three of them slowed carbohydrate digestion more effectively in lab tests than the diabetes drug acarbose
- These coffee compounds work by blocking the same digestive enzyme that turns starch into glucose, helping sugar enter your bloodstream more gradually instead of spiking sharply after meals
- The discovery shows your daily cup of coffee contains measurable bioactive molecules that directly interact with blood sugar metabolism
- Lab testing confirmed consistent enzyme-blocking effects, strengthening the evidence that these compounds are biologically active rather than random plant chemicals
- Long-term blood sugar control still depends on correcting insulin resistance and restoring cellular energy production, not relying on coffee alone
Scientists recently discovered new compounds in roasted coffee beans — and in lab tests, some of them outperformed a common diabetes medication at slowing down carbohydrate digestion. The drug they compared it to, acarbose, works by blocking an enzyme in your gut that breaks starch down into sugar. The enzyme is called alpha-glucosidase — it sits in the lining of your small intestine and snips complex starches into simple glucose molecules.
When that enzyme is slowed, sugar enters your bloodstream more gradually after a meal instead of all at once. That’s a big deal for anyone dealing with blood sugar issues. What makes this finding stand out is that these aren’t compounds scientists already knew about.
The research team identified six previously unknown molecules in coffee, isolated three of them, and put them to the test. The results were striking enough to warrant a closer look at what’s actually going on inside your morning cup — and what it means for blood sugar management.
Scientists Found New Coffee Compounds That Slow Sugar Spikes
In the study published in Beverage Plant Research, scientists didn’t just separate coffee into random chemicals and hope something worked.1 They first tested roasted Arabica coffee extracts to see which parts actually slowed the enzyme that breaks down carbohydrates. Then they focused only on the parts that showed real effects. That matters because it means these compounds were selected based on performance, not chance.
• They split coffee into pieces and tested each one — The researchers divided a concentrated coffee extract into 19 different parts and tested each part to see if it could slow the sugar-releasing enzyme. Only a small group showed strong activity. Instead of wasting time on inactive parts, they zoomed in on the ones that clearly made a difference. Think of it like testing 19 keys and quickly figuring out which few actually open the lock.
• They discovered three completely new coffee compounds — From the most active group, the team isolated three brand-new natural compounds that hadn’t been described before. They named them caffaldehydes A, B and C. Each one was carefully tested to see how strongly it slowed the enzyme that breaks starch into sugar.
All three new compounds shared the same main structure, but they had slightly different fatty acid “tails” attached. The version with the longer fatty acid tail showed the strongest enzyme blocking — think of it like a longer key that fits more snugly into the enzyme’s active site, making it harder for starch molecules to get in. That shows how even small chemical differences change how powerfully a natural compound works in your body.
• All three compounds outperformed a common diabetes drug — The scientists compared the three newly identified coffee compounds to acarbose, a medication used to slow carbohydrate digestion. In lab testing, each of the three compounds blocked the enzyme more effectively than acarbose under the same conditions. In simple terms, it took less of each coffee compound to achieve the same level of enzyme slowdown as the drug, with one compound showing the strongest effect of all.
• They found three more hidden compounds without fully isolating them — After identifying the main three, the researchers used advanced scanning technology to search for similar compounds in the rest of the coffee extract. They identified three additional new compounds that looked structurally related to the first group. These were found even though they were present in much smaller amounts. This tells you coffee contains more active molecules than previously recognized.
• They confirmed how these compounds work in the body — The targeted enzyme sits in your digestive tract and helps turn complex carbohydrates into glucose. When this enzyme slows down, sugar enters your bloodstream more gradually instead of flooding it all at once. The study clearly states that the three main compounds were responsible for this enzyme-blocking effect in the tested extract.
The researchers ran the enzyme tests multiple times and reported consistent results. The numbers stayed close across repeated experiments, which means the effect was reliable in the laboratory setting.
How to Fight Diabetes at the Source
You just learned that specific compounds in roasted Arabica coffee block the same enzyme targeted by a common diabetes drug. That matters. But isolated lab findings are only part of the picture. Enzyme-blocking is one layer of blood sugar control. The deeper question is why your cells aren’t handling glucose properly in the first place. If you want steady blood sugar, you have to correct the root problem: impaired glucose handling driven by mitochondrial dysfunction and insulin resistance.
Your mitochondria are the energy generators inside every cell — when they work well, they efficiently convert glucose into adenosine triphosphate (ATP), the molecule your cells actually run on. Focus first on restoring cellular energy production, because when your cells burn fuel efficiently, glucose doesn’t linger in your bloodstream and cause damage. Here are six direct steps you can take.
1. Get more from your coffee by drinking it clean — The compounds in this study came from roasted Arabica beans, which means regular brewed coffee is a natural source. But how you prepare and drink it matters. Choose organic, single-origin Arabica beans to minimize pesticide exposure. Grind them fresh and brew with filtered water.
Skip artificial creamers, flavored syrups, and sugar — these add inflammatory ingredients that work against the very blood sugar benefits you’re trying to gain. If you use a creamer, opt for grass fed dairy, including whole milk or cream. Black coffee or coffee with clean fats keeps those bioactive compounds front and center without sabotaging your metabolism.
2. Increase carbohydrates strategically — Most adults need 250 grams of carbohydrates daily for optimal cellular energy, and more if you’re physically active. If you restrict carbohydrates long term, you drive reductive stress — an excess of electrons that jams up your mitochondria’s energy-producing machinery — and impair mitochondrial ATP production.
Start with easily digested carbs like fruit and white rice, especially if your gut health is compromised. Then, gradually add in root vegetables, non-starchy vegetables, starchy vegetables like squash or sweet potatoes, beans and legumes, and finally minimally processed whole grains — only if your gut can handle them. Gradual increases restore metabolic flexibility.
3. Remove seed oils completely and replace them with stable fats — Excess linoleic acid (LA) from seed oils disrupts mitochondrial energy production and promotes insulin resistance. That’s a root driver of unstable blood sugar.
Eliminate seed oils, including corn, soybean, canola, sunflower, and safflower oils, along with commercial salad dressings, packaged snacks like crackers, and most restaurant foods. Replace them with grass fed butter, ghee or tallow. Lowering tissue LA over time improves cellular energy efficiency and reduces oxidative stress.
4. Build muscle with adequate protein and collagen — Muscle tissue absorbs glucose directly from your bloodstream — the more lean mass you carry, the more capacity your body has to clear excess blood sugar without relying heavily on insulin. Aim for 0.8 grams per pound of ideal body weight, or 1.76 grams per kilogram.
One-third of that intake should come from collagen sources, like bone broth. This supports structural integrity and metabolic resilience. If you’re over 40, this step becomes even more important because muscle loss accelerates insulin resistance.
5. Use sunlight and targeted movement to improve glucose handling — Daily sun exposure enhances mitochondrial function and nitric oxide production. Morning light sets your circadian rhythm and improves metabolic signaling. Combine that with one hour of walking daily — start gradually with 15 minutes and work your way up — and progressive strength training. Movement improves insulin sensitivity immediately.
Sunlight amplifies cellular energy production. If you’ve been regularly consuming seed oils, avoid midday sun exposure (10 a.m. to 4 p.m.) for at least the first six months after eliminating them, as LA stored in skin tissue increases your risk of sunburn.
6. Know Your HOMA-IR score — a simple test for insulin resistance — Recognizing insulin resistance early is essential, as it’s a warning sign for your metabolic health — one that often precedes Type 2 diabetes. The HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) test is a valuable diagnostic tool that helps assess insulin resistance through a simple blood test, so you can spot issues early and make necessary lifestyle changes.
Created in 1985, it calculates the relationship between your fasting glucose and insulin levels to evaluate how effectively your body uses insulin. Unlike other more complex tests, HOMA-IR requires just one fasting blood sample, making it both practical and accessible. The HOMA-IR formula is as follows:
HOMA-IR = (Fasting Glucose x Fasting Insulin) / 405, where
• Fasting glucose is measured in mg/dL
• Fasting insulin is measured in μIU/mL (microinternational units per milliliter)
• 405 is a constant that normalizes the values
If you’re using mmol/L for glucose instead of mg/dL, the formula changes slightly:
HOMA-IR = (Fasting Glucose x Fasting Insulin) / 22.5, where
• Fasting glucose is measured in mmol/L
• Fasting insulin is measured in μIU/mL
• 22.5 is the normalizing factor for this unit of measurement
Anything below 1.0 is considered a healthy HOMA-IR score. If you’re above that, you’re considered insulin resistant. The higher your values, the greater your insulin resistance. Conversely the lower your HOMA-IR score, the less insulin resistance you have, assuming you are not a Type 1 diabetic who makes no insulin.
Interestingly, my personal HOMA-IR score stands at a low 0.2. This low score is a testament to my body’s enhanced efficiency in burning fuel, a result of increased glucose availability. By incorporating additional carbohydrates into my diet, I provided my cells with the necessary energy to operate more effectively.
This improved cellular function has significantly boosted my metabolic health, demonstrating how strategic dietary adjustments lead to better insulin sensitivity and overall metabolic performance.
If you drink coffee daily, recognize that it contains bioactive compounds that interact with glucose metabolism. But don’t rely on coffee alone. Real metabolic recovery requires correcting insulin resistance, restoring mitochondrial energy production, and removing the environmental stressors that sabotage your cells. When you address the root, the numbers follow.
FAQs About Newly Discovered Coffee Compounds
Q: What did scientists discover in coffee beans?
A: Researchers identified six previously unknown natural compounds in roasted Arabica coffee beans. Three of these were isolated and tested in the lab, where they slowed the same digestive enzyme targeted by the diabetes drug acarbose. The coffee compounds worked more strongly than the drug under identical lab conditions.
Q: How do these coffee compounds affect blood sugar?
A: They slow down an enzyme in your digestive tract that breaks starch into glucose. When that enzyme is slowed, sugar enters your bloodstream more gradually after a meal instead of spiking quickly. Slower absorption helps reduce sharp blood sugar swings.
Q: Does this mean coffee cures diabetes?
A: No. The study was done in a laboratory setting, not in human clinical trials. It shows that roasted Arabica coffee contains bioactive compounds that influence carbohydrate digestion. It doesn’t prove that drinking coffee alone reverses diabetes. Blood sugar control depends on overall metabolic health.
Q: Why is insulin resistance the real issue to address?
A: Insulin resistance means your cells don’t respond properly to insulin, forcing your body to produce more of it to manage blood sugar. Over time, this leads to chronically elevated insulin and glucose levels. Measuring your HOMA-IR score gives a clearer picture of how well your body handles glucose and whether you’re improving.
Q: What practical steps support healthy blood sugar regulation?
A: Choose clean, organic Arabica coffee without added sugars or artificial creamers. Eliminate seed oils to reduce metabolic stress. Eat adequate carbohydrates to support cellular energy, especially from whole fruits and digestible starches. Build muscle with sufficient protein, including collagen. Get daily sunlight and consistent movement to improve mitochondrial function and insulin sensitivity.
Europe Establishes Its First Clinical Guide for Photobiomodulation in Cancer Care

Analysis by Dr. Joseph Mercola February 14, 2026
Story at-a-glance
- Photobiomodulation (PBM) is a light-based therapy that uses specific wavelengths to interact with body tissues, influencing cellular activity without heat and supporting recovery across both medical and general wellness settings
- Europe recently released its first formal clinical guide for PBM in oncology, marking a shift toward standardized use of light-based supportive care across cancer treatment centers
- Clinical research shows PBM is most strongly supported for managing oral mucositis and radiation-related skin damage, two common cancer complications that can interfere with eating, speaking, and treatment continuity
- Beyond cancer care, PBM has been studied for wound healing, nerve pain, musculoskeletal recovery, skin health, and hair loss, with consensus reviews supporting its safety when properly applied
- Effective PBM depends on correct wavelength selection, dosing, and device quality, with red and near-infrared light delivering biologically active energy when used within established therapeutic ranges
Chemotherapy and radiation remain central to modern cancer treatment, yet they often place a heavy burden on the body, affecting everything from your ability to eat and speak to the health of your skin and nerves. For patients and clinicians alike, addressing these treatment-related complications continues to be a persistent challenge. In response, oncologists have begun exploring light-based approaches as a way to reduce these secondary burdens.
Light has shaped life on Earth since the first single-celled organisms used it to generate energy billions of years ago — and your cells still respond to specific wavelengths in ways that influence not just sleep-wake cycles but also healing. Photobiomodulation (PBM) is a treatment approach that harnesses this relationship between light and biology, with research backing its benefits in various medical fields.
Europe has recently taken a significant step in bringing this therapy into mainstream cancer care. A newly released guide represents the first comprehensive European standard for using PBM in oncology, establishing standards for a therapy that many clinicians have yet to fully explore.1 This development reflects a broader shift in how supportive cancer care is being approached.
Europe Sets a Formal Framework for PBM in Oncology
In October 2025, the French-speaking Association for Supportive Care in Cancer (AFSOS) introduced the first European reference guide for the use of PBM in oncology. The announcement was made during the 16th National Congress of Oncology Supportive Care, held in Lille, France. This marks the first formal clinical standard for PBM in European oncology.2
• The guide sets clear clinical standards for PBM use — Led by Dr. Antoine Lemaire of Valenciennes General Hospital, the guide outlines when and how PBM should be integrated into supportive cancer care. It emphasizes that many clinicians remain unfamiliar with PBM despite its growing evidence base, and it positions the new reference document as a tool to close this knowledge gap. The aim is to standardize usage, so patients receive consistent care across treatment centers.
• Well-established uses of PBM across supportive cancer care — Cancer treatments place significant stress on tissues that divide rapidly or rely on delicate structural integrity, such as the lining of the mouth, skin, nerves, and connective tissue. Among PBM’s applications in oncology, the strongest clinical support exists for treating mucositis and radiodermatitis, both of which are common and painful complications of cancer treatment.
Mucositis refers to the painful inflammation and ulceration of the mucous membranes lining the digestive tract, which can make eating and swallowing extremely difficult for patients undergoing chemotherapy or radiation. Radiodermatitis refers to skin damage caused by radiation exposure and can range from redness and dryness to blistering and open wounds. It is common in breast, head and neck, and pelvic cancers.3
• The guide also covers other applications where evidence is moderate but promising — These conditions span multiple types of tissue and treatment-related complications, including:4,5
◦Lymphoedema — Persistent swelling caused by impaired lymphatic drainage after surgery or radiation.
◦Xerostomia — Dry mouth resulting from salivary gland damage during head and neck radiation treatment.
◦Trismus — Restricted jaw movement linked to muscle or joint stiffness after radiation.
◦Osteoradionecrosis — Bone injury and breakdown caused by impaired blood flow after radiation.
◦Dysphagia — Difficulty swallowing due to tissue inflammation or neuromuscular impairment.
◦Dysphonia — Voice changes or hoarseness from irritation or injury to vocal structures.
◦Dysgeusia — Altered or reduced taste perception related to chemotherapy.
◦Chemotherapy-induced neuropathy and alopecia — Nerve pain, numbness, and hair loss triggered by cytotoxic drugs.
◦Palmoplantar erythroderma — Redness, swelling, and tenderness of the palms and soles linked to certain chemotherapies.
• PBM delivers low-intensity light to stimulate mitochondrial activity without heat — The guide describes PBM therapy as “a mechanism in which red, near infrared, or blue light is delivered to damaged target tissues.” The approach relies on controlled light exposure rather than thermal effects and is applied using devices selected according to tissue depth and treatment location.
However, while the guide includes blue light within its technical definition of PBM, I do not recommend artificial blue light exposure for therapeutic use, as it disrupts circadian signaling and has well-documented effects on sleep regulation, hormonal balance, and systemic health. For this reason, red and near-infrared wavelengths remain the focus of safer and more biologically aligned applications.
• Around 100 cancer centers in France are currently equipped with PBM devices — These clinics use either laser or light-emitting diode (LEDs) equipment. While lasers tend to deliver more focused penetration, LEDs provide broader diffusion, and both can be effective depending on the clinical need. The choice of tool, treatment duration, and dosing parameters all depend on the area being treated and the depth of tissue involvement.
Therapeutic dosing generally falls within the range of 10 to 12 joules per square centimeter, but each device has its own set of instructions to ensure the light reaches the target tissue at the correct strength. Sessions typically last about 20 minutes, often administered once or twice per week in protocols that span eight to 16 sessions. Adjustments are made based on symptom severity and location.
• The therapy is also expanding beyond oncology — Private clinicians increasingly use these devices in sports medicine and gynecologic care, while patient associations advocate for broader access. Some patients now request PBM directly, which raises the need for oncology clinicians to understand PBM and recognize appropriate indications within cancer care pathways.
• Despite growing adoption in clinical settings, PBM faces several barriers to wider use — The most pressing is the lack of dedicated reimbursement. At present, the cost of PBM is typically bundled into consultation fees, which limits its scalability.
The guide raises concerns about the rise of home-use PBM devices, noting that many sold online lack proper safety certification, deliver inadequate or poorly calibrated doses, or emit wavelengths that can pose health risks. While this caution is valid, it’s also important to recognize that not all consumer devices fall into this category.
When properly designed, dosed, and used with informed guidance, some at-home units can be a useful part of a broader therapeutic approach. The key is understanding how to choose equipment that’s both safe and effective. I’ll go into more detail later on how to evaluate devices and what to look for if you’re considering one for personal use.
By laying out clear protocols, validated use cases, and technical considerations, the new European guide brings much-needed structure to a therapy that has, until now, been applied unevenly across clinics. To understand why European oncologists are standardizing PBM protocols, it helps to grasp how light actually interacts with your cells.
Understanding the Science Behind Light
Not all light affects your body the same way. What matters is the wavelength — essentially, how long or short each wave of light is, measured in nanometers. Each part of the light spectrum interacts with your cells differently, and only a specific range carries the ability to penetrate deeply enough to influence healing, energy production, and inflammation without causing harm.
• Solar rays can be divided into three categories — Ultraviolet (UVA, UVB, and UVC) account for 7% of the solar spectrum. Visible light (violet, indigo, blue, green, yellow, orange, red), ranging from 400 to 700 nanometers, accounts for 39% of the spectrum. Invisible infrared (near-, mid-, and far-infrared) light, ranging from 700 to 10,000 nanometers, accounts for 54% of the spectrum.
• This range is called the optical window — The ideal optical window is about halfway through the near-infrared range, between 600 and 900 nanometers. Within this optical window, the wavelengths are long enough to penetrate the body and reach deep into the tissues, but they’re not readily absorbed by hemoglobin, melanin, and water. The optical window sweet spot is around 800 to 810 nanometers.
• Penetration depth varies by wavelength — Red light starts around 600 nanometers. In the range of about 630 to 660 nanometers, red light typically reaches a few millimeters into tissue, making it relevant for skin and superficial structures. Meanwhile, near-infrared light begins above 700 nanometers. At around 800 to 850 nanometers, it penetrates much deeper, reaching muscles, joints, and other underlying tissues.
Longer wavelengths, closer to 1,050 nanometers, can penetrate even further, with research exploring their interaction with deeper tissue and neural structures, although these applications remain an active area of investigation.
• The key target within your cells is an enzyme called cytochrome c oxidase — This is a protein embedded in your mitochondria that acts as the final gatekeeper in cellular energy production. When this enzyme absorbs red or near-infrared light, it accelerates the production of adenosine triphosphate (ATP), the molecule your body uses for cellular energy. This increase in ATP supports everything from tissue repair to immune signaling and metabolic resilience.
• PBM influences melatonin production, but not the kind produced by your brain at night — Instead, near-infrared light stimulates melatonin synthesis inside the mitochondria, which account for roughly 95% of the melatonin produced in your body. By comparison, the melatonin secreted by the pineal gland during nighttime represents only 5% of your body’s total melatonin output.
Within mitochondria, melatonin serves as a powerful antioxidant. It neutralizes free radicals generated during normal energy production and helps protect mitochondrial structures from oxidative damage. Because mitochondria are present in nearly every cell, this mechanism helps explain why red and near-infrared light can exert effects across such a wide range of tissues.
• Nitric oxide is another key player — When light triggers its release from cellular storage sites, it leads to improved circulation by widening blood vessels and reducing inflammation. The result is better blood flow to damaged tissues, improved oxygen delivery, and support for immune and repair processes in areas under stress.
This broad impact on core biological functions has made PBM an area of growing interest in fields beyond oncology.

Other Health Benefits of PBM Beyond Cancer Care
A clinical consensus published in the Journal of the American Academy of Dermatology reviewed the available evidence on PBM and found that it shows therapeutic benefit for the following conditions:6
• Wound healing — Chronic wounds can persist for weeks or months due to poor blood flow, infection risk, or high levels of inflammation. This includes diabetic foot ulcers, venous leg ulcers, pressure ulcers (bedsores), and burns. PBM supports healing in these cases by improving circulation, reducing inflammation, and promoting tissue repair, especially when used alongside standard wound care.
• Peripheral nerve conditions — Damage to the peripheral nervous system can cause burning, tingling, numbness, or shooting pain in the limbs. PBM has been shown to help reduce nerve-related pain and restore some sensory function, particularly in cases of diabetic neuropathy or chemotherapy-induced nerve injury.
Additional studies have looked at its potential to relieve post-herpetic neuralgia (shingles-related nerve pain), improve bladder control, and stabilize blood pressure reflexes, though more data is needed in those areas.
• Musculoskeletal performance and recovery — PBM may influence muscle performance and fatigue depending on dose and wavelength. While further high-quality research is needed, these findings suggest promising uses in sports medicine and physical rehabilitation.
• Cognitive function and neurodegeneration — Though consensus was not reached for all neurological conditions, PBM has been studied for its effects on cognitive performance, memory, and attention. Applications explored in early or experimental studies include brain injury, dementia, chronic migraines, Alzheimer’s disease, and Parkinson’s disease.
I also recently finished a hypothesis paper, which has yet to be published, in which I propose that near-infrared light absorbed by mitochondria triggers local melatonin synthesis, which may activate powerful antioxidant defenses within brain cells. This mitochondrial melatonin system appears distinct from pineal melatonin and operates without circadian rhythms.
According to the model, near-infrared exposure initiates a cascade involving glutathione amplification and SIRT3 activation that offers targeted protection against oxidative stress. I believe this light-triggered mechanism could help defend neurons from age-related degeneration, particularly when combined with adequate intake of glutathione precursors like glycine and N-acetylcysteine (NAC).
• Dermatological and aesthetic uses — PBM has found a place in clinical dermatology, particularly for improving scar appearance and skin rejuvenation. In patients with androgenic alopecia, PBM has also been shown to promote hair regrowth when used at appropriate wavelengths and dosages.
• Oral applications — PBM has been described as generally well tolerated when used for maxillofacial conditions. While the consensus review did not detail specific clinical outcomes, separate research published in The Journal of the American Dental Association reports that PBM may be used as an adjunctive therapy in dental settings to support wound healing, reduce inflammation, and help manage pain.7
As with any biologically active therapy, outcomes depend not just on what condition is being treated, but on how the therapy is delivered. Understanding how to choose the right device — and how to dose it correctly — is essential for translating the science of PBM into safe, practical results.
Practical Guidance for Choosing a PBM Device and Using It Effectively
Using PBM to effectively improve your general wellness depends on both how much light is delivered and how it is delivered. Dose, wavelength, and device quality work together to determine whether PBM produces a meaningful biological response. The aim is to apply enough energy to activate cellular processes without exceeding the range where the effect begins to diminish. Here are some tips to keep in mind:
• Aim for the therapeutic middle range rather than going too low or too high — Research commonly uses doses between 5 and 50 joules per session, with a joule representing the amount of energy delivered in watts per second. This reflects a well-established principle in PBM: insufficient energy produces weak or no biological response, while excessive energy can reduce or inhibit the intended effect.
• Use about 25 joules per session for general whole-body wellness — This level can be reached using a large PBM panel and corresponds to roughly 10 minutes of exposure to the front of the body and 10 minutes to the back. This session length provides enough energy to support cellular signaling and tissue recovery without overwhelming the system.
• Match the device to your health goal, required depth, and daily routine — Consider what you intend to treat, how deep the light needs to reach, and how easily the device fits into your daily routine. Adjustable settings that control wavelength and dosage improve flexibility and help tailor sessions to your needs.
Always choose a clinically validated device from a reputable manufacturer to ensure safety, reliability, and accurate energy delivery. A practitioner trained in PBM can help tailor your dosing schedule based on individual health goals and response patterns.
• Choose a mixed red and near-infrared unit when you want both surface and deep-tissue effects — This device allows you to address both surface-level and deeper tissue issues simultaneously. However, achieving these combined benefits requires spending about 50% more time using the device compared to using a device that emits only near-infrared light.
• Select low-EMF, low-flicker devices to reduce unnecessary stress exposure — Mito Red is one example of a PBM manufacturer that has addressed several common concerns found in many light therapy devices. One of the key features is its extremely low electromagnetic field (EMF) output, measuring under 1 milligauss at a 6-inch distance and dropping to background levels beyond that.
In contrast, some infrared panels emit 5 to 10 gauss or more when used at close range, which may be a consideration for those sensitive to EMFs. They also eliminated light flicker, a subtle but measurable pulsing that tends to occur in infrared light devices and can affect neurological comfort over time. Visit their website to explore the full product line, including portable units, full-body panels for home use, commercial-grade panels, and red-light room systems.
• Consider using sauna therapy — Far infrared saunas, in particular, provide a practical way to deliver therapeutic wavelengths while also supporting detoxification through sweat. Learn more in “Infrared Sauna After Training Speeds Recovery and Supports Athletic Performance.”
• PBM complements natural light exposure — Regular time in natural sunlight remains the best way to receive a full spectrum of beneficial light wavelengths. But for many people, daily exposure is inconsistent or limited by season, lifestyle, or environment. PBM can be a great health investment to fill the gaps when natural light isn’t available, but it’s meant to supplement — not replace — sunlight exposure.
Frequently Asked Questions (FAQs) About Photobiomodulation
Q: What are the benefits of PBM in patients undergoing cancer treatment?
A: PBM is used in cancer care to help manage treatment-related side effects. Clinical research shows it may reduce the severity and duration of oral mucositis, ease pain in the mouth and throat, improve tolerance to radiation-related skin reactions, and support recovery of tissues affected by chemotherapy or radiation.
By helping preserve your ability to eat, speak, and maintain skin and nerve comfort, PBM may also reduce treatment interruptions and improve overall quality of life while you are undergoing cancer therapy.
Q: Why do red and near-infrared light matter more than other wavelengths?
A: Red and near-infrared wavelengths fall within a range that allows light to penetrate tissue without being excessively absorbed by skin pigment, blood, or water. This makes them better suited for interacting with deeper tissues compared to shorter wavelengths.
Q: Should I use blue light as part of PBM therapy?
A: Blue light is included in some technical definitions of photobiomodulation, but artificial blue light exposure can disrupt circadian signaling and sleep regulation. For this reason, focusing on red and near-infrared light aligns better with overall biological health outside tightly controlled medical settings.
Q: Can I use a PBM device at home?
A: Some at-home devices are designed to deliver appropriate wavelengths and doses, but quality varies widely. Look for clinically validated equipment with clear specifications and avoid devices that lack safety certification or accurate output information. Guidance from a knowledgeable practitioner helps reduce misuse.
Q: Does PBM replace spending time outdoors?
A: PBM does not replace natural sunlight. Time outdoors provides a broader spectrum of light and supports circadian health in ways devices cannot fully replicate. PBM works best as a supplement when regular outdoor light exposure is limited by the environment or schedule.
How Urolithin A Drives Mitochondrial Renewal and Slows Immune Aging
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2026/01/15/urolithin-a-immune-system-benefits.aspx
Analysis by Dr. Joseph Mercola January 15, 2026
Story at-a-glance
- As you age, your thymus produces fewer newly formed cells responsible for responding to unfamiliar pathogens, reducing your immune system’s adaptability. This shift, combined with persistent inflammation, defines the core features of immune aging
- Urolithin A, a postbiotic compound, stimulates mitochondrial renewal in aging immune cells. A recent study shows it can increase naïve-like T cells and strengthen immune surveillance in just four weeks of supplementation
- Clinical findings show that urolithin A boosts mitochondrial renewal pathways, increases markers linked to mitochondrial biogenesis, and improves immune cell metabolism
- Beyond immune health, studies reveal that urolithin A influences cancer pathways, enhances muscle strength and endurance, improves fatty liver markers, and reshapes metabolic signaling involved in obesity and insulin resistance
- Beyond using urolithin A, you can also support your mitochondria by lowering linoleic acid intake, eating the right carbohydrates, limiting environmental toxins, and supporting NAD⁺ production with niacinamide
Most people tend to think of immune health mainly as a defense against seasonal colds or infections. In reality, its influence runs deeper. A well-balanced immune system helps regulate inflammation, maintain internal stability, and support energy and vitality. As the years pass, however, the immune system undergoes natural changes that are part of the aging process itself.1
Mitochondrial breakdown drives much of this decline, yet effective strategies to address immune aging are still lacking. To address this gap, a recent study published in Nature Aging investigated whether urolithin A, a postbiotic compound, could stimulate mitochondrial clean-up and rebuilding, ultimately helping to renew aging immune cells from within.2
What Happens to Your Immune System as You Age?
As you grow older, your immune system undergoes what the Nature Aging study describes as “global remodeling of the immune system,” which involves several well-documented shifts that change how effectively your immune system responds to everyday challenges.3
• Thymic output declines, reducing newly formed T cells — One of the core shifts involves the thymus, the organ that produces naïve T cells. With age, thymic activity declines, leading to fewer newly formed T cells entering circulation. Because naïve T cells are your front-line responders to unfamiliar pathogens, this reduction makes it harder for your immune system to mount strong first-time responses.
• Memory T cells accumulate, limiting adaptability — As naïve T cells drop, memory T cells become a larger share of your immune system. Memory cells help with threats you have already encountered but bring little support when something new appears. This shift explains why older adults respond less robustly to vaccines and face more risk from novel infections.
• Inflammaging becomes a defining feature of later life — As immune cell patterns shift with age, the body enters a state of persistent, low-grade inflammation. This phenomenon, known as inflammaging, reflects higher levels of inflammatory mediators circulating at rest and is considered one of the central characteristics of an aging immune system. Learn more about this in “‘Inflammaging’ Is a Lifestyle Phenomenon, Not a Universal Aging Trait.”
Together, these changes outline the core features of immune aging. They show why an older immune system tends to be less flexible, slower to respond to new threats, and more prone to persistent inflammation.
New Insights Into Urolithin A’s Immune and Mitochondrial Actions
The featured study involved 50 healthy adults between 45 and 70 who received either 1,000 mg of urolithin A per day or a placebo for four weeks. Researchers collected blood at the beginning and end of the study to observe how immune cells shift over that short window. This made it possible to see whether mitochondrial support translates into measurable changes in immune cell composition and behavior.4
• Urolithin A increased naïve CD8 T cells — Participants who received urolithin A showed a significant increase in naïve CD8 T cells, which behave more like younger, freshly formed immune cells. These cells respond more reliably to threats and carry fewer markers of exhaustion. Alongside this shift, CD8 T cells also showed about a 15% increase in their ability to use fatty acids for energy, suggesting better metabolic flexibility.
• Innate immune cells showed stronger surveillance profiles — Urolithin A supplementation increased a subtype of natural killer (NK) cells known for being the most active in identifying and eliminating infected or abnormal cells. These NK cells deliver the strongest cytotoxic activity, so having more of them strengthens rapid-response immunity.
• Signs of increased mitochondrial biogenesis appeared within CD8 T cells — Participants who took urolithin A showed higher expression of markers associated with PGC-1α, the protein that guides mitochondrial growth and renewal.
This points to a process where immune cells were not only clearing out older, less efficient mitochondria but also strengthening their overall energy system, giving them a more reliable foundation when they activate or stay engaged for longer periods.
• Functional tests showed stronger immune responses — When researchers activated T cells in the lab, those from the urolithin A group produced more tumor necrosis factor (TNF), a cytokine that signals rapid immune engagement. Monocytes also demonstrated better uptake of E. coli particles, indicating improved ability to recognize and engulf microbial targets.
• Molecular programming shifts within immune cells — Single-cell analysis showed that urolithin A reshaped inflammatory and metabolic pathways across multiple immune cell types, pointing toward coordinated changes that support stronger, more balanced immunity as you age. As the researchers explained:
“Exploratory single-cell RNA sequencing demonstrated urolithin A (UA)-driven transcriptional shifts across immune populations, modulating pathways linked to inflammation and metabolism.
These findings indicate that short-term UA supplementation modulates human immune cell composition and function, supporting its potential to counteract age-related immune decline and inflammaging.”5
Taken together, the trial shows that urolithin A influences the immune system on several levels within a relatively short period of time. While the study was designed as an early investigation, its findings offer a clear indication that supporting mitochondrial health may play a meaningful role in maintaining immune resilience as you age.

Urolithin A’s Effects Across Different Conditions
Beyond immune aging, urolithin A has been studied for a variety of other health effects as well. Research shows that it interacts with several biological pathways relevant to long-term health, which has led scientists to examine its role in several conditions, including:6
• Cancer — Urolithin A shows anticancer activity mainly in preclinical work. Laboratory and animal studies report that it slows the growth of several tumor types, promotes cancer cell death (apoptosis), and interferes with pathways that support proliferation and invasion.
Reviews describe these effects in models of breast, pancreatic, oral, and other cancers, and highlight actions such as inhibiting NF-κB signaling, activating FOXO1 (a transcription factor that supports cellular stress responses and regulates genes involved in survival and repair), and triggering autophagy-related cell death in tumor cells.7
• Muscle strength — In a randomized clinical trial published in JAMA Network Open, older adults aged 65 to 90 were given 1,000 mg of urolithin A per day for four months. Results showed significantly improved muscle endurance, measured as the number of contractions until fatigue in both hand and leg muscles, compared with placebo.8
A separate trial in middle-aged adults, published in Cell Reports Medicine, found that daily urolithin A supplementation led to improvements in quadriceps strength, enhanced exercise performance, and favorable shifts in several biomarkers associated with mitochondrial health within a similar timeframe.9
• Fatty liver — In a mouse model of fructose-induced fatty liver disease, urolithin A supplementation reduced hepatic steatosis and improved the balance between fat creation and fat breakdown in the liver by impairing lipogenesis and enhancing β-oxidation.10 In parallel, a Biomedicines review notes that urolithin A attenuates inflammation in liver tissue in metabolic models, helping to stabilize the hepatic environment under stress.11
• Metabolic disorders — Urolithin A has been studied extensively in models of obesity, Type 2 diabetes, and metabolic syndrome. In laboratory and animal models, urolithin A reduced triglyceride accumulation in fat cells and liver cells by lowering genes that drive fat creation and activating AMPK, an energy-sensing pathway that shifts cells toward burning stored fat instead of stockpiling it.12
More detailed experiments in preadipocytes (the precursor cells that eventually mature into fat cells) found that urolithin A lowered triglyceride content and suppressed the expression of several key genes that help regulate fat storage, glucose transport, and fatty acid binding, so reducing their activity helps keep fat accumulation under control while still allowing fat cells to form normally.13
Several studies also showed that urolithin A protected mice and rats from high-fat diet-induced obesity and insulin resistance by supporting thermogenesis, increasing browning responses (a shift toward a more metabolically active type of fat cell), reducing oxidative stress, and lowering inflammatory activity within adipose tissue.14
Better Urolithin A Delivery Is Still Under Way
Before you try to increase your urolithin A levels, it’s important to understand how your body forms it, why many people produce very little, and what determines whether supplementation works as intended. Understanding these details helps you decide the most effective and practical way to support your mitochondrial renewal pathways.
• Urolithin A is naturally produced in your body — When you eat foods rich in ellagitannins, a class of polyphenols found in pomegranates and some berries, these plant compounds are first converted into ellagic acid and then transformed into different urolithins depending on which microbial species live in your gut.15
• Not everyone forms urolithin A efficiently — The ability to generate urolithin A depends entirely on your gut microbiota composition. Factors such as age, diet, medication use, and overall microbial diversity influence whether the conversion occurs.
Only about 40% of adults produce detectable levels after consuming ellagitannin-rich foods like pomegranate juice. Even among individuals who do produce it, output varies widely, which is why supplementation has become the most reliable way to achieve consistent levels.16
• How it’s delivered matters — Because urolithin A exerts its mitophagy action inside the mitochondria, it’s important to deliver it directly into the mitochondria. This is essential because mitochondria are constantly being damaged.
They contain the furnace of energy production, and because most people consume excess linoleic acid (LA) from seed oils, their mitochondria get destroyed prematurely. These damaged mitochondria need to be recycled; if they just accumulate, your cellular energy production collapses.
• Newer systems are being developed to improve this targeted delivery — Without mitochondrial targeting, much higher doses of urolithin A are required to reach the same intracellular effect (about 1,000-fold higher). Most formulations currently available do not include this targeting technology, but next-generation approaches are being designed to deliver urolithin A directly to the mitochondria so effective levels can be achieved with lower amounts.
• Urolithin A is also part of a paired approach — Urolithin A must be used in conjunction with PQQ (pyrroloquinoline quinone), which activates PGC-1α to stimulate mitochondrial biogenesis. This combination is important, as urolithin A clears out the damaged mitochondria while PQQ generates fresh replacements.
While better delivery systems are on the way, you already have practical ways to strengthen mitochondrial function, many of which support the same pathways urolithin A influences.
Practical Strategies to Improve Your Mitochondrial Health
Recognizing how strongly your mitochondria influence immune aging gives you a clearer sense of where to focus your efforts. The choices you make each day shape how well your mitochondria function, which in turn affects your metabolic stability and long-term immune resilience. Several practical steps can help you support these organelles and create a healthier foundation for cellular energy and overall health:
1. Remove processed foods and vegetable oils from your diet — Processed products are typically made with seed oils that contain large amounts of LA, which interferes with mitochondrial function and reduces your ability to generate energy efficiently. Nuts, seeds, and most restaurant meals contribute additional LA, since commercial kitchens rely heavily on these oils.
Chicken and pork often contain higher levels of LA as well, due to the way they are commonly raised and fed. Center your diet around whole foods and choose low-LA fats such as grass fed butter, tallow, and ghee. Aim to keep your daily LA intake under 5 grams, ideally aiming for less than 2 grams. Use an online nutrition tracker like the upcoming Mercola Health Coach App to monitor your intake.
2. Optimize your carbohydrate intake for cellular fuel — A balanced diet rich in the right carbs and free of ultraprocessed foods feeds your mitochondria with the glucose they’re designed to burn. Focus on whole fruits and white rice first, then gradually bring in root vegetables, legumes, and well-tolerated grains as your gut improves. Aim for 250 grams of healthy carbs daily to keep your thyroid working at full capacity.
3. Reduce exposure to environmental toxins — Your cells are exposed to synthetic chemicals every day. Substances such as endocrine-disrupting chemicals (EDCs) from plastics, estrogen-mimicking compounds like xenoestrogens, and widespread electromagnetic fields (EMFs) interfere with how efficiently your mitochondria produce energy. When these exposures accumulate, mitochondrial function declines.
Taking steps to limit this burden can make a meaningful difference. Choose household items made from natural materials whenever possible, and store food in glass instead of plastic. Creating a low-EMF sleeping environment is also helpful, as it allows your cells to recover overnight with less external stress. Collectively, these changes reduce the strain placed on your body.
4. Get proper sun exposure — Regular sun exposure supports cellular energy by stimulating the production of mitochondrial melatonin, which provides strong antioxidant protection inside your cells. However, it’s best to avoid direct sun during peak hours (typically 10 a.m. to 4 p.m. in most parts of the U.S.) until you have minimized seed oils in your diet for at least six months, as the buildup of LA in your tissues makes your skin more prone to sunburn.
5. Boost NAD+ Levels — Taking niacinamide at a dose of 50 mg three times a day helps raise your NAD+ levels, which supports mitochondrial energy production. Adequate NAD+ is essential for proper cell-death signaling and strengthens your immune system’s ability to recognize and clear damaged cells.
Frequently Asked Questions (FAQs) About Urolithin A
Q: What is urolithin A, and how does it work?
A: Urolithin A is a postbiotic compound that your body produces when gut bacteria break down ellagitannins from foods like pomegranates and berries.
It works by stimulating mitophagy, the process that clears out damaged mitochondria from your cells and promotes the growth of new, healthy ones. This mitochondrial renewal is particularly important for your immune cells, which need strong energy production to function effectively as you age.
Q: How does my immune system change as I get older?
A: As you age, your thymus produces fewer naïve T cells, which are your front-line responders to new threats. At the same time, memory T cells accumulate, making your immune system less adaptable to novel infections. You also experience persistent low-grade inflammation that becomes a defining feature of immune aging. Together, these changes make your immune system slower to respond and less flexible.
Q: Can my body produce urolithin A on its own?
A: Your body can produce urolithin A only if you eat foods that contain ellagitannins and you have the specific gut bacteria needed to convert them. Many adults lack the microbes required, which is why only about 40% produce detectable levels even after consuming ellagitannin-rich foods.
Q: What are the benefits of urolithin A beyond immune health?
A: Studies show effects in several areas, including muscle endurance, metabolic function, fat storage, and cellular stress responses. Preclinical research also reports anticancer activity, with urolithin A influencing pathways tied to tumor growth and autophagy. Human trials have confirmed gains in muscle performance and mitochondrial biomarkers.
Q: What other steps can I take to improve my mitochondrial function?
A: You can support your mitochondrial health through several practical daily choices. Lowering your LA intake by cutting back on seed oils and processed foods helps protect your mitochondria from ongoing oxidative damage. Eating the right kinds of carbohydrates also gives your cells the steady glucose they rely on for energy.
Reducing your exposure to environmental toxins and creating a low-EMF sleeping environment further lightens the stress placed on your cells each day. Regular sun exposure adds another layer of support by stimulating mitochondrial melatonin, and taking niacinamide helps raise your NAD⁺ levels, which your mitochondria rely on to function efficiently.

Reclaim Your Cellular Health with the Mitochondria Protocol
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2026/01/11/mitochondria-protocol-cellular-health.aspx
Analysis by Dr. Joseph Mercola January 11, 2026
Story at-a-glance
- Linoleic acid embeds in mitochondrial membranes where free radicals are generated, producing toxic aldehydes like 4-HNE that damage the electron transport chain and accelerate metabolic degradation throughout the body
- Mitochondria form adaptive energy networks responding to sleep, exercise, and stress, producing your body weight in ATP daily while performing essential maintenance like clearing debris and supporting new brain cell growth
- Brain diseases like Alzheimer’s and Parkinson’s stem from failing mitochondria that struggle to produce energy, remove harmful proteins, and maintain cellular communication, leading to cognitive decline and movement problems
- Strengthen mitochondria through varied exercise routines (higher-intensity movement builds new mitochondria, cardio improves efficiency, strength training increases numbers), consistent sleep schedules, daytime-aligned eating, and cautious sauna use at moderate temperatures
- Minimize linoleic acid intake to less than 2 to 3 grams daily by avoiding vegetable oils and ultraprocessed foods. You can accelerate clearance using C15:0 fat from raw, grass fed dairy
How your mitochondria are currently working is deeply tied to the current state of your cellular health. If these energy producers are not working optimally, then your health ultimately suffers. According to a study published in 2024, damaged mitochondria become the foundation of chronic diseases like cardiovascular disease, metabolic syndrome, neurodegenerative disease and cancer.1
So, how do you fix your mitochondria? In her podcast, The Longevity Show, longevity expert Dr. Hillary Lin2 goes over a wealth of useful recommendations with the goal to helping you produce better, healthier cellular energy.3
While Lin makes great points, I would like to preface this article by highlighting one important component that she missed when it comes to improving mitochondrial health — minimizing your linoleic acid (LA) intake, as it embeds into your mitochondria.
I believe that excess LA intake is one of the biggest roadblocks to achieving optimal cellular health. In fact, I will go as far as saying that minimizing it takes precedence over the recommendations made by Lin. Once you have your LA consumption under control, her recommendations will fall into place — all of which are also helpful.
The Impact of Linoleic Acid on Your Mitochondrial Health
LA is one of the most damaging toxins affecting your cellular health. It’s in everyone’s best interest to make sure consumption is minimized, as it sets off a cascade of chronic disease:
• Excess LA intake is the primary driver of metabolic degradation — Your mitochondria generate approximately 90% of cellular reactive oxygen species (ROS), with the vast majority produced specifically at the electron transport chain in the inner mitochondrial membrane. This makes the inner mitochondrial membrane the single most critical site of ROS generation in the body.
Since approximately 0.2% to 2% of oxygen consumed by mitochondria is converted to superoxide (the precursor to other ROS), and given that almost all free radicals originate from electron leakage at Complexes I and III of the electron transport chain, having oxidation-prone LA molecules embedded directly in this membrane represents a catastrophic design flaw when LA is consumed in excess.
• Mechanism of damage — When you ingest LA, it eventually embeds itself in the inner mitochondrial membrane. From there, it precipitates metabolic degradation products, particularly reactive aldehydes such as 4-hydroxynonenal (4-HNE). These aldehydes damage the electron transport chain, which is the most precious biological machinery in your entire body responsible for ATP production.
• Why this process is uniquely dangerous — Almost all free radicals are generated within the electron transport chain itself. Now, LA is a highly fragile, perishable molecule extremely susceptible to oxidation. Having it embedded in the place where free radicals are generated is like storing gasoline beside a spark generator. In other words, it’s the worst possible place for such an oxidation-prone molecule.
• The cascade of damage in your health — When 4-HNE and other reactive aldehydes are generated, important systems such as the electron transport chain, mitochondrial DNA, nuclear DNA, and important intracellular proteins and hormones are affected.
Minimizing Your LA Intake Is the Most Vital Factor in Maintaining Optimal Mitochondrial Health
Again, the solution is to lower your LA consumption as much as possible. To start, it’s found in vegetable oils used for cooking, such as soybean, corn, safflower, and sunflower oils. In fact, these oils provide over 80% of LA found in Western diets. LA is widely used in ultraprocessed foods and restaurants as well, so avoid these products as much as possible. Focus on making healthy meals at home.
• I recommend keeping it below 2 to 3 grams per day — To help you monitor your intake, you can download my upcoming Mercola Health Coach app, which contains the Seed Oil Sleuth. This feature will help you calculate all the LA in your meals to a tenth of a gram.
• C15:0 helps clear LA from your body faster — LA has a half-life of about two years, so the damage stored in your system will take a long time to be purged. To help speed up this process, consider taking C15:0 fat, also known as pentadecanoic acid. It primarily comes from grass fed dairy, yet most people only consume 100 to 200 milligrams of it daily. The great thing about this approach is that it cuts LA clearance timeline in half.

• Another tip is taking a beta-alanine supplement — In a previous article, I noted that it acts as a powerful antioxidant that helps neutralize oxidative damage caused by LA. It works by becoming a sacrificial target for ROS and advanced lipid peroxidation end products (ALEs) like 4-HNE. This spares DNA, mitochondria, and proteins from further harm.

The Mitochondria Form a Huge Energy Network
Moving on to Lin’s lecture, she starts by explaining that your everyday energy, thinking ability, and even how you age are shaped by your mitochondria. She says they work like a power plant, only there are billions of them inside your body that make constant decisions affecting your health. Instead of treating these structures as simple “batteries,” they’re more than that — they guide your energy, your repair processes, and even the lifespan of your cells.
• How your daily life shapes your mitochondria — Your mitochondria form “living networks” that respond to how you sleep, exercise, and manage stress. They constantly adjust their output based on what you put your body through each day. Because they react to your daily choices, your lifestyle directly shapes how well you create and use energy. And as I mentioned, excess LA intake is a major factor that cripples this energy network.
That said, Lin noted that you’re not stuck with the energy level you have now. Your habits influence how these networks behave, meaning that supporting your mitochondria through healthy lifestyle changes will help you improve how you feel, think, and even age. This is something I wholeheartedly agree with, too.
• A glimpse of the scale of energy flowing through you — Your mitochondria produce and recycle roughly your entire body weight in adenosine triphosphate (ATP) every single day.
In your brain, one cell alone uses billions of ATP molecules every second, like a tiny city lit up with millions of bulbs all switched on at once, and they do not just sit still. They move toward areas that need more energy and even fuse together to share resources, especially when you push your muscles or challenge your mind.
In your muscle cells, they form “power-generating networks” to keep your movement going, and during tough thinking tasks, your brain cells build similar networks to meet the higher demand.
• The entire power grid in your body is malleable, which has huge consequences for how you age — Your cellular energy system is like a city-wide power infrastructure, where both the quality of each plant and how well they link together matter. According to Lin, “mitochondrial function is not fixed,” and researchers now see that declining performance in these power plants shows up before many age-related diseases do.
Again, Lin stresses that this decline isn’t inevitable, and that specific lifestyle strategies will strengthen your cellular grid and even slow or reverse some aspects of cellular aging.
• Failing mitochondria impact brain health — Lin then goes into the topic of Alzheimer’s disease and offers a view that goes far beyond the typical focus on protein buildup in the brain. She explains that failing mitochondria can trigger this buildup. When your mitochondria falter, they not only struggle to make energy — they stop removing harmful proteins like amyloids and block communication lines between brain cells.
She describes your mitochondria as a “maintenance crew,” explaining that when they are healthy, it clears debris, protects the connections between neurons, and even supports the growth of new brain cells. When they weaken, the entire system becomes cluttered, slow, and unstable.
• How mitochondria function under Parkinson’s disease — Next, Lin explores the role of mitochondria in Parkinson’s disease. She highlights a gene called PTEN-induced kinase 1 (PINK1), which acts like an inspector that flags damaged mitochondria so they can be removed through mitophagy, a process she describes as “the eating of mitochondria.”
When PINK1 doesn’t work properly, damaged mitochondria pile up. This hits brain areas that steer movement, leading to the symptoms people recognize in Parkinson’s disease. Lin then connects mitochondrial stress to mood disorders, explaining that long-term psychological stress keeps your mitochondria running at maximum output.
Over time, this overload, also called mitochondrial allostatic load, wears the system down, lowering efficiency and causing problems to cascade through both your emotional and physical health.
• The brain responds positively when you care for its energy system — You’re not stuck with the mitochondrial health you have right now. Lin reveals that exercise boosts the creation of brand-new mitochondria in the brain, upgrading your internal power grid and improving your ability to think clearly under pressure.
She also noted that the bacteria in your gut send signals along the gut-brain axis that influence how your brain’s mitochondria function, showing how much your mental sharpness depends on habits outside your head as well.
•Sleep plays an important role — Your brain performs essential mitochondrial repairs during regular sleep cycles, and when those cycles break down, your energy system suffers. Disrupted sleep undermines mitochondrial repair, which is why poor sleep leaves you foggy, irritable, and less able to think clearly the next day.
Lin makes it clear that these everyday habits are more than healthy choices — they are tools for protecting your brain against fatigue, psychiatric conditions, and long-term diseases such as Alzheimer’s and Parkinson’s.
Actionable Steps Part 1 — How to Strengthen Your Inner Power Grid
After Lin lays down the science on how mitochondria work to create an energy network within your body, she introduces her own set of strategies designed to help you strengthen this very system using everyday habits. Again, focus on minimizing LA intake first, then you can try implementing her protocol.
• Get regular exercise and vary your routine — Lin describes high-intensity interval training (HIIT) as a way to activate PGC-1α, which she calls your body’s “general contractor” for building new mitochondria. For example, sprint intervals boost mitochondrial content “about 2.3 times more” than standard HIIT programs, making them the most powerful option for building new energy factories quickly.
Traditional cardio, by contrast, upgrades the efficiency of the mitochondria you already have, while strength training increases the number of mitochondria inside each muscle fiber.
• Improvements depend heavily on how well you recover — Lin warns that “more isn’t necessarily always better,” especially if you struggle with fatigue conditions. Your mitochondria need time to recycle damaged parts through a process she compares to cleanup and reconstruction, and sleep plays a major role in this.
During quality sleep, proteins such as Dynamin-related protein 1 (DRP1) act like inspectors that identify and remove damaged components, keeping your energy machinery running smoothly. She adds that you can improve this nightly repair system by sticking to consistent sleep-wake times and sleeping in a cool, dark room.
• Your eating schedule affects your energy production — Eating during the daytime (your natural active window) helps maintain strong mitochondrial rhythms. Even shorter periods of daytime-aligned eating help your cells switch between fuel types and stay resilient under stress.
Using herself as an example, Lin explains that she struggles with this problem while living in a “night-focused city,” making it clear that aligning eating habits with daylight hours is important for long-term energy stability.
Actionable Steps Part 2 — Utilizing Temperature to Train Mitochondria
Heat and cold are powerful training tools for your mitochondria. Lin explains that heat exposure, such as from a sauna, can boost your mitochondria’s respiratory capacity by nearly 25%. In fact, she says that this strategy is “almost like cheating,” because those gains match what you’d normally achieve through exercise alone.
• Heat activates special repair proteins — This helps your cells strengthen their energy production systems while also encouraging the formation of new mitochondria. Lin recommends 170 to 200 degrees Fahrenheit (F) for traditional sauna use when appropriate for your health.
While I agree with Lin regarding the benefits of using a sauna, I believe her recommended temperatures are on the extreme side. A good starting point for beginners is around 120 degrees F, three times per week. Personally, my body can handle temperatures up to 160 to 170 degrees F, and that level isn’t wise for beginners. If you’re just starting, keep it low and increase gradually.
For more information on how to safely use a sauna, read “Infrared Sauna After Training Speeds Recovery and Supports Athletic Performance.”
• Cold exposure creates a different type of adaptation — Lin noted that cold plunges, cold showers, and winter swimming can push your mitochondria to become better heat producers through a process called uncoupling.
This controlled form of stress teaches your energy system to work more efficiently under pressure and improves your ability to regulate temperature. She compares this to the natural cold exposure your ancestors experienced daily, making today’s deliberate cold practices a modern version of that challenge.
While the findings are sound, I generally don’t recommend this strategy. In a previous article, I noted that cold plunges activate stress hormones that may provide some temporary benefit, but I believe that it will lower your overall resilience. But if you’d still like to try it, listen to your body and have a buddy with you. If you start to feel weak, nauseated, or lightheaded, get out of the water and warm up immediately.
• A combined protocol that uses both heat and cold — If you think that the heat/cold strategy works for your case, you can follow Lin’s suggestion below, so you can make the most of it.
Begin with five to 20 minutes of heat, followed by one to three minutes of cold, starting small and adjusting as your body adapts. Lin gives an important warning — avoid cold exposure immediately after intense workouts if building muscle is your goal, because this temperature briefly reduces the signals your body needs for growth. However, if your goal is recovery, especially reducing inflammation, cold after exercise becomes helpful instead.
• Supplement recommendations — Lin touched on specific nutrients your mitochondria rely on for strength and repair. She noted that CoQ10 is “premium fuel,” alpha-lipoic acid as your “cleanup crew,” nicotinamide adenine dinucleotide (NAD+) precursors for ATP production, and omega-3 fatty acids as structural support for mitochondrial membranes.
Lin also highlights glycine, N-acetylcysteine (NAC), B vitamins, and newer options such as urolithin A and spermidine, which help maintain high-quality mitochondrial recycling and protein repair. Lastly, she emphasized that supplement choices are best personalized and not one-size-fits-all. If you’re considering taking any of these, consult with a health care expert first.
Actionable Steps Part 3 — Building Your Energy Upgrade Plan
Lin presents a step-by-step framework to help you apply her recommended strategies in a sustainable way, which is done in three phases:
• The first phase the foundation, lasting four to six weeks — During this stage, your focus is on basic routines that stabilize your energy system. These include consistent sleep, exercise appropriate for your current fitness, and nutritious eating with enough vegetables, some omega-3, and protein.
Lin suggests that a gentle 12-hour daytime eating window is an optional starting point if it fits your health needs. The goal here is not advanced training but building stability first.
• The second phase, lasting two to three months, emphasizes refinement — Here, you begin moving workouts earlier in your day, adding supplements that match your health profile, and creating an ideal sleep environment — cooler temperatures, dark rooms, and supportive bedding.
This is also where sauna sessions and temperature-contrast therapy become helpful additions. You can keep a 12-hour eating window or narrow it to around eight daytime hours if it feels comfortable and realistic for your lifestyle.
• The third phase is advanced optimization, intended for people who already feel stable — Increase your exercise intensity, add more targeted supplements, and fine-tune the timing of your habits — exercise, meals, heat, cold, and sleep — so they work together. Lin encourages people in this phase to monitor their progress and adjust with help from clinicians trained in mitochondrial biomarkers, since this stage involves more detailed tweaking of your energy system.
• Special guidance for long COVID and chronic fatigue — Lin acknowledges that these conditions require a gentler approach. She recommends “mitochondrial zone training,” which uses heart rate monitoring to keep exercise at a low, steady intensity below your aerobic threshold.
If you’re affected by long COVID or have fatigue issues, Lin points out you can try her three-phase protocol, but progress is, ideally, extremely slow. Sleep becomes the top priority, and supplements are introduced cautiously. Eating windows are looser, and temperature fluctuations are gentle rather than extreme.
The most important takeaway here is that pushing too hard early “can lead to greater damage long-term,” so Lin encourages planning your regimen to match your current capacity, not your ideal one.
Frequently Asked Questions (FAQs) About the Mitochondria Protocol
Q: Why are mitochondria so important for your overall health?
A: Mitochondria are your body’s energy producers, and when they stop working well, your cells fall into low power mode. A 2024 study showed that mitochondrial dysfunction is involved in major chronic diseases, including heart disease, brain disorders, metabolic issues, and cancer. This means your long-term health is closely tied to how well your mitochondria create and manage energy.
Q: What role does linoleic acid (LA) play in damaging mitochondrial health?
A: Excess LA — found heavily in vegetable oils and ultraprocessed foods — embeds into your mitochondrial membranes, where it breaks down and produces toxic chemicals like 4-HNE. These byproducts damage the electron transport chain, mitochondrial DNA, and your cell’s energy machinery. Reducing LA intake to less than 2 to 3 grams per day is one of the fastest ways to protect your mitochondria and restore healthier energy production.
Q: How do lifestyle habits influence mitochondrial performance?
A: Your mitochondria respond to how you sleep, eat, move, and manage stress. Exercise helps build new mitochondria; good sleep repairs them; and daytime-aligned eating supports steady energy rhythms. Poor habits — especially disrupted sleep — weaken your energy grid, affecting your thinking, mood, and resilience.
Q: What mitochondrial strategies does longevity expert Dr. Hillary Lin recommend?
A: Dr. Lin highlights three pillars — varied exercise (HIIT, cardio, and strength training), smart recovery (high-quality sleep and rest), and circadian-aligned eating. She also supports heat and cold exposure as energy-training tools and mentions nutrients like CoQ10, alpha-lipoic acid, NAD+ boosters, omega-3s, glycine, NAC, urolithin A, and spermidine for added support — though personalized guidance from an expert is recommended.
Q: How can someone safely improve mitochondrial health over time?
A: Lin outlines a three-phase plan — start with improving sleep quality, simple exercise, and balanced daytime nutrition; refine your routine with supplements and temperature therapy; and later optimize timing of meals, workouts, and heat/cold exposure. If you’re affected with long COVID or chronic fatigue, she emphasizes extremely gentle pacing and avoiding overexertion because pushing too hard can actually worsen mitochondrial damage.
Why Is Migraine More Common in Women Than Men?
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2025/12/18/why-migraine-more-common-women-than-men.aspx
Analysis by Dr. Joseph Mercola December 18, 2025
Story at-a-glance
- Migraines affect women three to four times more often than men, largely due to hormonal fluctuations that sensitize the brain’s pain pathways and increase vulnerability to stress, poor sleep, and inflammation
- Estrogen both primes and triggers migraine attacks — high levels heighten sensitivity, while sudden drops before menstruation or after childbirth cause the electrical instability that sparks pain
- Natural progesterone helps counteract estrogen’s pro-inflammatory effects, calming nerve excitability and reducing migraine frequency during hormonally active years
- Mitochondrial dysfunction is a major driver of migraines; reducing linoleic acid from seed oils and restoring nutrients like magnesium, CoQ10, and B vitamins strengthens your brain’s energy supply and resilience
- Supporting melatonin through morning sunlight, minimizing blue light exposure at night, and maintaining oral and circadian health naturally lowers inflammation, helping prevent migraines and improve overall brain function
Migraines aren’t just headaches — they’re a full-body storm that hijacks your senses, drains your energy, and derails your day. The pain is often piercing or throbbing, but what makes migraines especially disruptive is how they affect your thinking, mood, and ability to function. Even ordinary things like light, sound, or certain smells often feel unbearable during an attack.
For millions of women — who experience migraines three to four times more often than men1 — these episodes are recurring events that reshape daily life, work, and relationships. Rather than being confined to one system of your body, migraines start in your brain’s electrical and vascular networks and spread outward, involving nerves that control sensation, vision, and balance.
Over time, frequent attacks exhaust your body’s energy supply, strain your stress response, and interfere with sleep, setting up a cycle that’s hard to break.
Researchers are now discovering that this condition has as much to do with how your brain handles energy and hormones as it does with pain itself. Differences in brain wiring, cellular metabolism, and hormonal rhythms make women especially vulnerable, but they also reveal clear pathways for prevention and healing. Understanding these underlying drivers helps you see migraines not as random attacks but as signals from an overtaxed system ready for repair.
Hormones Drive the Gender Gap in Migraines
Before puberty, boys and girls experience migraines at roughly the same rate, but as estrogen levels rise and fluctuate through adolescence, the difference becomes dramatic. An article published in The Conversation highlights that as many as 1 in 3 women live with migraines, compared to only 1 in 15 men — a disparity rooted in biology rather than behavior.2
• Migraine attacks are linked to specific phases of a woman’s life when hormones swing the most — Women often notice that migraine episodes cluster around predictable “milestone moments,” such as puberty, menstruation, pregnancy, and perimenopause. Each of these phases is marked by changes in estrogen. These hormonal rollercoasters make the female brain more vulnerable to energy depletion, sensory overload, and inflammation — all factors that intensify pain perception.
The late Dr. Ray Peat, a pioneer in bioenergetic medicine, long proposed that excess estrogen plays a central role in triggering migraines — and modern research has begun to validate that idea.
Research published in Frontiers in Molecular Biosciences found that estrogen heightens the sensitivity of cells surrounding the trigeminal nerve — the major nerve that controls facial sensation and pain — and nearby blood vessels, amplifying pain signals that lead to migraine attacks.3
Because estrogen peaks during a woman’s reproductive years, this also explains why migraines are not only far more common in women but most prevalent during this stage of life. The same research noted that progesterone appears to have a protective effect. This makes sense if estrogen is causative, as natural progesterone is an estrogen blocker.
• Fluctuating estrogen directly alters brain activity and pain signaling — Sudden hormone drops also trigger a wave of abnormal electrical activity known as cortical spreading depression — a slow electrical ripple that temporarily disables normal brain function.4 This wave helps explain why migraine symptoms go beyond head pain and often involve dizziness, nausea, or sensitivity to light.
At the same time, when estrogen dips, the trigeminal nerve becomes overstimulated, heightening sensitivity and causing the throbbing pain that defines a migraine. This connection might seem like a contradiction: how can both a high level and a sudden drop in estrogen cause trouble? Think of it this way: High estrogen is like pressing the “sensitivity” button on your brain’s pain control panel, turning the volume up to maximum.
It doesn’t cause the attack yet, but it primes your system for pain. The sudden drop in estrogen — the withdrawal — is the actual trigger; it’s the moment someone yanks the plug from the wall. That shock to the already hyper-sensitive system causes the electrical chaos (cortical spreading depression) and the resulting migraine.
• Pregnancy and menopause each reshape migraine patterns in distinct ways — During early pregnancy, when hormones shift rapidly to sustain fetal growth, migraines often become more intense or unpredictable. However, as pregnancy progresses and hormone levels stabilize, many women notice dramatic improvement or even complete remission of attacks. After birth, the sudden hormonal drop often reignites migraine episodes.
Perimenopause, the transitional period before menopause, brings another unpredictable phase — random surges of estrogen from the ovaries often trigger new or worsened attacks. Yet once menopause is reached and hormone levels flatten, many women experience partial or total relief, illustrating how stability of estrogen matters most.
• Mitochondrial inheritance explains why migraine tends to run in maternal family lines — The Conversation also discussed how genetics — and specifically mitochondrial DNA — help explain why migraines frequently appear in mothers, daughters, and granddaughters. Mitochondria are the tiny energy generators inside cells that produce adenosine triphosphate (ATP), your body’s main energy currency. They’re inherited only from your mother.
People with migraines have fewer functional enzymes within their mitochondria, meaning their brains operate in a constant state of energy deficit. When additional stress — like lack of sleep, poor diet, or hormonal swings — further drains this energy supply, a migraine is triggered. This insight links hormonal instability with cellular energy dysfunction, showing why migraine management needs to address both.
Brain Structure and Stress Patterns Explain Women’s Migraine Burden
A narrative review published in Neurological Sciences explored how biological and social differences between men and women influence migraine risk, symptoms, and treatment outcomes.5
The review found that global migraine prevalence is 20.7% in women and 9.7% in men, with even larger gaps in countries like Italy, where 32.9% of women and only 13% of men experience the condition. These numbers show why women often face greater daily disruption, lost workdays, and emotional strain from chronic migraine than men.
• Women experience more intense, longer, and more disabling attacks than men — According to the review, female migraine sufferers report longer episodes, higher recurrence rates, and slower recovery compared with males. Women are also 1.34 times more likely to fall into the highest category of migraine-related disability.
The researchers attribute these differences to the combined effects of hormonal fluctuations, stress response patterns, and brain structure — specifically, how women’s nervous systems respond to sensory and emotional stimuli. Female brains exhibit more pain-responsive regions, meaning stress, light, and noise produce a stronger reaction.
• Workplace stress and sleep disruption compound migraine risk — The review also highlighted night shifts, irregular sleep patterns, and emotionally demanding roles influence migraine risk. Shift work disrupts your circadian rhythm — your body’s natural sleep-wake cycle — which affects hormonal regulation and brain energy metabolism. People working fixed evening shifts had up to 56% higher odds of seeking migraine treatment compared to daytime workers.6
• Environmental triggers at work create a hidden layer of risk — People exposed to bright lights, chemical odors, or poor air quality in workplaces reported more frequent headaches. The study linked these environmental stressors to “sick building syndrome,” a condition where prolonged exposure to indoor pollutants worsens symptoms until leaving the environment brings relief.
• Hormones, genetics, and environment combine to shape women’s migraine risk — The Global Burden of Disease study ranked migraine as the fourth leading cause of years lived with disability for women, compared with eighth for men, according to a report from the University of Colorado Anschutz Medical Campus.7
Dr. Danielle Wilhour, assistant professor in the department of neurology, noted that about 50% to 60% of women with migraine experience menstrual-related attacks. Women with migraine also more often struggle with anxiety and depression, while men tend to experience physical comorbidities such as obesity.
Wilhour added that women are more likely to adopt preventive approaches, while men often treat migraines only after they begin. She also highlighted neuromodulation devices that deliver mild electrical impulses to nerves in the head or neck, interrupting pain transmission without drugs. These tools offer alternatives for those who want to avoid migraine medications or reduce side effects.

Most Migraines Trace Back to Excess Linoleic Acid
While hormones and genetics play a role, most migraines stem from a deep-rooted problem in your mitochondria — and one of the biggest saboteurs of mitochondrial health is excess linoleic acid (LA). This polyunsaturated fat, abundant in seed oils and other ultraprocessed foods, acts as a mitochondrial toxin that disrupts your cells’ ability to produce energy efficiently.
• Excess LA damages your mitochondria, fueling inflammation and pain — When LA oxidizes, it forms toxic byproducts. These compounds attack mitochondrial membranes and proteins, blocking normal energy production. With less ATP, your brain becomes far more vulnerable to migraine attacks.
• Damaged cardiolipin disrupts energy flow inside your cells — Cardiolipin, a specialized fat in the inner membrane of your mitochondria, is essential for forming “supercomplexes” that generate energy.
When too much LA replaces the healthier omega-3 fats that should be there, cardiolipin loses its structure and no longer supports efficient ATP production. The result: sluggish energy metabolism and increased oxidative stress, both of which prime your brain for migraine pain.
• Impaired cell renewal lets damaged cells persist — Healthy cardiolipin also triggers apoptosis — the process of clearing out malfunctioning cells. When oxidized LA damages cardiolipin, this self-cleaning mechanism fails, allowing defective cells to survive and perpetuate inflammation and dysfunction.
• Processed seed oils are the main culprits — The most common sources of LA are vegetable, or seed, oils (soybean, corn, safflower, sunflower, canola), fried and processed foods, restaurant meals, and grain-fed meats like conventional pork and chicken.
Even many olive and avocado oils are adulterated with cheaper seed oils. Although reducing your total LA burden takes time, early benefits appear within weeks as healthier fats replace damaged ones in your mitochondria. Ideally, limit your LA intake to below 3 grams per day. You can figure out how much you’re consuming with my Mercola Health Coach app, which comes out later this year.
Practical Steps to Restore Mitochondrial Health and Prevent Hormone-Driven Migraines
If you’re living with migraines, you already know how unpredictable and exhausting they are. What’s less obvious is that the pain often starts deep inside your cells. When your mitochondria struggle to make enough energy, your brain becomes more reactive to stress, hormones, and environmental triggers. Restoring mitochondrial health, balancing hormones, and protecting your nervous system are the keys to lasting relief.
1. Reduce LA to protect your mitochondria — Excess LA damages your mitochondria and mimics estrogen, triggering migraines. To protect your brain’s energy system and stabilize hormones, limit LA to under 3 grams per day by avoiding seed oils like soybean, corn, safflower, sunflower, canola, and cottonseed, along with fried, processed, and restaurant foods made with them. Choose stable fats such as grass fed butter, ghee, or tallow instead.
To track your intake, I recommend you download my Mercola Health Coach app when it’s available this year. It has a feature called the Seed Oil Sleuth, which monitors your LA intake to a tenth of a gram. Lowering LA helps your mitochondria recover, reduces inflammation, and helps lessen migraine frequency.
2. Support melatonin — your brain’s built-in antioxidant — Melatonin does much more than regulate sleep. It shields your brain at the cellular level by neutralizing free radicals and calming inflammation that drives migraine pain. To optimize it naturally:
• Get bright morning sunlight to anchor your circadian rhythm — this raises alertness during the day and boosts melatonin release at night.
• Limit blue light exposure after sunset by dimming lights, using incandescent or salt lamps, and wearing blue-blocking glasses if you use screens.
• Sleep in total darkness to allow full melatonin release overnight. Studies show melatonin can reduce headache frequency by 51%, intensity by 53%, and duration by 46%, making it a strong natural alternative to pharmaceutical drugs.8
3. Rebuild your nutrient reserves to fortify brain energy — Migraines are often linked to deficiencies in magnesium, B vitamins (especially B2, B6, folate, and B12), vitamin D, and coenzyme Q10 (CoQ10). These nutrients are essential for healthy mitochondrial energy production and nerve function. If you struggle with frequent migraines, increase your intake of magnesium-rich foods — like leafy greens — and consider magnesium threonate for better absorption into your brain.
For severe cases, intravenous (IV) magnesium often helps stop an attack midstream. CoQ10 supports the same energy pathways and works best when paired with magnesium over several months. Always aim to meet most of your nutrient needs through whole foods first — the exception being magnesium, because many are deficient and benefit from supplementation.
4. Care for your mouth to reduce inflammation throughout your body — Chronic oral inflammation is a hidden migraine trigger. Studies show women with migraines are far more likely to have gum disease or poor oral health.9 Use a gentle, fluoride-free toothpaste, skip alcohol-based mouth rinses, and brush your tongue daily or use a tongue scraper.
Oil pulling with coconut oil daily helps draw out bacteria and support oral detoxification. Visit a biological dentist twice yearly for deep cleanings and comprehensive exams — small improvements in oral health make a big difference in your overall inflammation load.
5. Find your personal triggers — and balance your hormones naturally — No two migraines are exactly alike, but tracking your patterns gives you the power to predict and prevent them. Keep a detailed migraine diary that records your sleep, stress, meals, weather changes, and menstrual cycle.
Over time, you’ll start to see clear connections between hormonal shifts and migraine attacks. Once you know when your triggers occur, you can act early — hydrating more, stabilizing your meals, or using stress-reduction techniques before symptoms begin.
For women whose migraines are clearly linked to hormonal fluctuations, supporting natural progesterone balance can make a meaningful difference. Natural progesterone helps calm brain excitability and offsets the pro-inflammatory effects of excess estrogen that often trigger migraine pain.
In addition to lowering your estrogen burden and LA intake, aspirin is an inexpensive and readily available option. As reported in a 2019 paper in The American Journal of Medicine, properly dosed aspirin can safely and effectively abort a migraine attack when taken early enough, and may also be used preventatively in lower doses.10
FAQs About Migraines in Women
Q: Why are migraines more common in women than in men?
A: Migraines affect women three to four times more often than men because of hormonal differences, particularly fluctuations in estrogen and progesterone. Estrogen increases brain sensitivity to pain, while drops in estrogen also trigger migraine attacks. Women’s reproductive years — when hormone levels shift the most — are also when migraines are most frequent and intense.
Q: How do hormones trigger migraine attacks?
A: High estrogen levels “prime” your brain for pain by increasing the sensitivity of the trigeminal nerve, which regulates facial sensation and headache pain. The sudden drop in estrogen that follows — such as before menstruation or after childbirth — acts as the final trigger, setting off electrical instability and inflammation that lead to migraine symptoms. Natural progesterone helps counter these effects by calming nerve excitability and balancing estrogen activity.
Q: What role does mitochondrial health play in migraines?
A: Mitochondria are the energy producers in your cells, and when they’re underperforming, your brain struggles to maintain stable energy. This energy deficit makes you more prone to migraine attacks. Reducing LA from processed seed oils and supporting mitochondrial nutrients like magnesium, CoQ10, and B vitamins help stabilize cellular energy and reduce migraine frequency.
Q: Are there natural ways to prevent or lessen migraine attacks?
A: Yes. Focus on stabilizing hormones and supporting cellular health:
• Lower your intake of LA to under 3 grams per day.
• Get morning sunlight and avoid blue light at night to support melatonin production.
• Eat nutrient-dense foods rich in magnesium and B vitamins, and consider supplementation if necessary.
• Track your hormonal cycle and migraine triggers.
• Practice stress management, regular sleep, and relaxation therapies like acupuncture or chiropractic care.
Q: What treatments or supplements are most effective for migraine relief?
A: Natural options that have shown measurable results include magnesium threonate, CoQ10, vitamin D, melatonin, and natural progesterone support. Melatonin alone has been shown to reduce headache frequency by more than 50%. For acute relief, properly dosed aspirin — taken early in an attack — has been shown to be both safe and effective, and it can also be used in lower doses for prevention.

Depression Strongly Influences Surgical Recovery and Healing Outcomes
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2025/12/01/depression-surgery-recovery.aspx
Analysis by Dr. Joseph Mercola December 01, 2025
Story at-a-glance
- Depression affects how your body heals after surgery by increasing inflammation and weakening your immune defenses, which lead to longer recovery times and higher complication rates
- Older adults with cancer who also have depression experience significantly higher post-surgical costs — nearly $25,000 compared to about $17,500 for patients without depression — showing that untreated mental health directly impacts both recovery and finances
- In patients undergoing spine surgery, depression nearly doubled the risk of delirium and tripled the likelihood of blood clots or infections, underscoring how mood disorders influence physical outcomes
- Depression triggers systemic inflammation and disrupts hormonal balance, particularly through chronically high cortisol levels, which slow wound healing and increase blood pressure — key drivers of poor recovery
- Addressing depression before surgery — through dietary changes, gut support, regular movement, sunlight exposure, and consistent rest — helps restore your body’s energy systems, reduces inflammation, and supports faster, more complete healing
Depression affects far more than your mood — it reaches into every system of your body, influencing how well you recover from illness, injury, or surgery. When your mind is under strain, your immune system weakens, inflammation rises, and your body’s repair processes slow down. That’s why people struggling with depression often take longer to heal, face more complications, and endure higher medical costs after surgery.
What’s striking is that depression often hides in plain sight. Its symptoms — fatigue, disrupted sleep, lack of motivation, and mental fog — are often dismissed as stress or aging. Yet these same signs reveal a deeper issue: your cells aren’t producing enough energy to keep your body functioning at full capacity. This shortage of cellular energy makes recovery harder and increases the risk of infections and chronic inflammation, both of which interfere with surgical healing.
Addressing depression — especially before an operation — isn’t just about emotional well-being. It’s about restoring your body’s energy systems so that you’re better equipped to handle the physical stress of surgery and recovery. Your mental state determines how effectively your body fights inflammation, repairs tissue, and manages pain — all key factors in whether you recover quickly or face setbacks.
In recent years, researchers have begun linking mental health directly to surgical outcomes, revealing that your brain-body connection is stronger than anyone once believed. The studies that follow explore how depression impacts postoperative recovery — and why addressing it early could make all the difference in your survival, resilience, and long-term health.
Depressed Cancer Patients Face Higher Post-Surgical Risk and Costs
A study examining outcomes in older adults with colorectal, hepatobiliary, and pancreatic cancers found that a diagnosis of depression, whether made up to a year before or after cancer detection, significantly worsens post-surgical recovery and drives up health care costs.1
Out of 32,726 participants, 1,731 had depression, and about three-quarters of them were prescribed antidepressants. The goal was to determine how depression — treated or untreated — affected recovery, hospital stays, readmissions, complications, and costs after surgery.
• Depressed patients faced tougher recoveries — Patients with depression faced higher risks of surgical complications, longer recovery times, and increased mortality. Those without depression fared best overall.
• Untreated depression drove costs up by thousands — The financial gap told a clear story. Non-depressed patients averaged $17,551 in total care costs. Those treated for depression spent about $22,086, while untreated depressed patients reached $24,897 — a 10.2% increase compared to patients without depression. These figures reveal that untreated mental health issues directly raise health care costs and slow recovery.
• Depression impairs your body’s ability to heal — Depression isn’t just a matter of mood. It interferes with self-care, disrupts immune responses, and increases inflammation — all of which slow wound healing. When depression goes untreated, patients are more likely to experience complications such as infections or delayed recovery.
• Experts call for integrating mental health into surgical care — Lead author Erryk S. Katayama explained that understanding mental health risk factors “can help create holistic and individualized treatment plans, anticipate and prevent complications, and ultimately optimize patient outcomes.” Senior author Dr. Timothy M. Pawlik added that treating depression may improve treatment compliance and overall self-care success.
• Your mindset matters before surgery — If you’re facing surgery, your emotional state isn’t secondary — it’s central. Addressing depression before an operation improves your physical resilience, shortens recovery time, and lowers costs. Simply put, healing starts long before you enter the operating room.
Depression Greatly Increases the Risk of Complications After Spine Surgery
As revealing as these findings are, they highlight a larger truth: depression doesn’t stay confined to your mind — it affects every system that determines how your body responds to injury, stress, and healing. The consistency of these results across very different types of surgery underscores a simple reality — no operation happens in isolation from your emotional health.
A study published in the Journal of Clinical Medicine reviewed 26 studies investigating how depression influences surgical recovery and complication rates in people undergoing spine surgeries.2 This meta-analysis evaluated outcomes like infection rates, reoperation frequency, and postoperative complications across tens of thousands of patients to determine whether depression altered the body’s ability to recover after major spinal procedures.
• Depressed patients experienced far more complications — The data revealed that depression was linked to a dramatic rise in surgical and medical complications. Depressed patients were almost twice as likely to experience delirium (sudden confusion or disorientation) and more than three times as likely to suffer from blood clots, including deep vein thrombosis and pulmonary embolism — conditions that often become life-threatening if untreated.
• Infections and neurological problems were far more common — Those with depression had higher odds of developing surgical site infections, urinary retention, or urinary tract infections, each of which can slow healing and prolong recovery. The odds of developing neurological injury — damage to nerves that control sensation and movement — were six times higher among depressed patients. These complications directly affect recovery time and quality of life after surgery.
• Hospital readmissions and reoperations increased significantly — Compared to non-depressed patients, those with depression were 35% more likely to be readmitted to the hospital and twice as likely to require a second operation. Even though their length of hospital stay was similar, their overall outcomes were worse, suggesting that the physical recovery process continued to be more complicated after discharge.
• Depression triggers systemic inflammation and disrupts immune balance — This means your body becomes less efficient at fighting infection or repairing tissue after injury. Depression also influences hormones like cortisol, which, when chronically elevated, slows wound healing and increases blood pressure. Together, these effects set the stage for poorer outcomes after surgery.

How to Strengthen Your Mind and Body to Overcome Depression
Depression weakens your body’s natural energy systems, making you feel tired, unmotivated, and disconnected from the world around you. It also affects your immune function, digestion, and ability to handle stress — the very systems you need to thrive, especially if you’re facing surgery. Before agreeing to any procedure, be sure it’s absolutely necessary. Ask questions, explore second opinions, and understand all your options so you can make the most informed decision possible.
Taking this pause to evaluate your choices also helps you begin shifting out of the helplessness that often surrounds depression. Regaining that sense of control and confidence is a powerful first step toward healing. You have far more control over this process than you may realize. By targeting the root causes that disrupt your body’s energy and mood balance, you can restore resilience from the inside out.
1. Remove seed oils and processed foods from your diet — Consuming ultraprocessed foods increases the risk of depression in older adults.3 These foods are loaded with linoleic acid (LA), a polyunsaturated fat that builds up in your tissues and damages mitochondria. This fat stresses your cells and impairs your brain’s ability to regulate mood. Start replacing vegetable oils — such as soybean, corn, and sunflower — with saturated fats like grass fed butter, ghee, or tallow.
Your target is less than 5 grams of LA daily, ideally under 2 grams. To track your intake, I recommend you download my Mercola Health Coach app when it’s available this year. It has a feature called the Seed Oil Sleuth, which monitors your LA intake to a tenth of a gram so you can stay in charge of your metabolism.
2. Rebuild your gut to repair your mood and immunity — Your gut and brain are in constant communication. When your microbiome — the community of bacteria living in your intestines — is imbalanced, it triggers inflammation that worsens depression. Your body needs about 250 grams of carbohydrates daily to maintain optimal cellular energy production, but too much fiber too soon ramps up endotoxin release and triggers digestive issues.
To fix this, focus on easily digestible carbohydrates like fruit and white rice first, then move to root vegetables and well-cooked legumes as your gut strengthens. When your digestion stabilizes, introduce whole grains that your body tolerates well. This step-by-step approach helps you restore balance, energy, and mood without unpleasant side effects.
3. Exercise regularly but gently — Movement helps regulate neurotransmitters that influence mood and energy production. One comprehensive review concluded that physical activity is 1.5 times more effective than the most prescribed antidepressants in reducing symptoms of depression and anxiety.4,5
Focus on daily walks and light strength training to improve circulation, oxygen delivery, and lymphatic flow. Even a 20-minute walk outdoors helps clear inflammation and supports better metabolic function — but gradually work your way up to one hour daily for best results.
4. Protect your mitochondria with daily sunlight — Expose your skin and eyes to morning sunlight to trigger natural energy production in your cells. This light signals your mitochondria to generate adenosine triphosphate (ATP) — your body’s energy currency — and stabilizes circadian rhythms. Avoid harsh midday sun until you’ve been off seed oils for at least six months; this helps prevent oxidative damage and rebuilds your skin’s tolerance to UV light.
5. Feed your body and mind with rest and rhythm — Healing starts with consistency. Keep regular sleep and meal times to support your circadian biology. To support high-quality sleep, dim your lights after sunset, and avoid screens late at night. When your body runs on rhythm, your stress hormones stabilize, inflammation drops, and your immune system can do its job — helping you recover faster and stronger after surgery.
FAQs About Depression and Surgical Recovery
Q: How does depression affect surgical outcomes?
A: Depression interferes with your body’s ability to heal by increasing inflammation and weakening your immune system. These effects slow wound repair, heighten infection risk, and make recovery longer and more difficult. Studies show that patients with depression experience more complications, higher readmission rates, and increased mortality after surgery compared to those without depression.
Q: Why does managing depression before surgery make such a difference?
A: Addressing depression before surgery gives your body a major advantage over going into an operation while depressed. Patients whose depression was managed had shorter hospital stays, fewer complications, and lower overall costs, while those who went into surgery untreated faced slower healing, higher inflammation, and a greater risk of readmission — clear proof that mental health directly determines physical recovery.
Q: What steps can I take to overcome depression naturally?
A: You can strengthen both mind and body by addressing the root causes of low mood and energy. Key steps include removing seed oils and processed foods, rebuilding gut health, getting daily sunlight, exercising regularly, and maintaining a consistent sleep routine. Each of these supports mitochondrial function, hormonal balance, and emotional stability.
Q: Is it true that diet affects mood and depression risk?
A: Yes. Research shows that consuming ultraprocessed foods increases the risk of depression. These foods contain fats like LA that damage mitochondria and promote inflammation. Replacing them with stable fats like grass fed butter, ghee, or tallow helps restore metabolic and mental health.
Q: What should I consider before having surgery if I’m struggling with depression?
A: First, make sure the procedure is truly necessary. Ask questions, explore second opinions, and understand your full range of options. Taking time to evaluate your choices helps you regain a sense of control — a key factor in overcoming depression. Strengthening your mental health before surgery not only supports faster healing but also improves your overall long-term outcome.
Adenomyosis Is a Hidden, Estrogen-Driven Cause of Severe Period Pain
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2025/08/23/adenomyosis-symptoms-causes-natural-treatment.aspx
Analysis by Dr. Joseph Mercola August 23, 2025
Story at-a-glance
- Adenomyosis is often mistaken for bad period pain or endometriosis, but it involves tissue growing into the uterine muscle, causing swelling, heavy bleeding, and knife-like cramps
- Many women suffer for years without a diagnosis because doctors misinterpret symptoms or rely on outdated assumptions that the condition only affects older women
- Research shows adenomyosis leads to serious complications like infertility, miscarriage, preeclampsia, and dangerously low hemoglobin levels requiring emergency transfusions
- Estrogen overload is the main driver of adenomyosis, and it’s made worse by birth control, plastics, vegetable oils, and hormone-disrupting chemicals found in everyday products
- You can start reversing estrogen dominance naturally by cutting synthetic hormones, avoiding xenoestrogens, restoring metabolism with the right carbs, and using natural progesterone
If your period pain feels unbearable — like a deep, throbbing ache or stabbing cramps that knock the wind out of you — it’s not something to brush off. Pain that severe isn’t normal. For millions of women, it’s the body’s warning signal for something deeper that’s often misunderstood or completely missed.
You’ve likely been told that heavy bleeding, pelvic pressure, and fatigue are just part of being a woman. But what if those symptoms point to a disease that’s quietly hijacking your uterus and flooding your body with inflammation? That’s the reality for countless women who are dismissed, misdiagnosed, or left in the dark for years, sometimes decades. This condition, known as adenomyosis, doesn’t always show up clearly on a scan.
It’s not taught well in medical school. And it’s rarely mentioned in mainstream conversations about women’s health. But it’s there, silently reshaping lives, month after month. I want to walk you through what the research now shows — why it happens, who’s at risk, and what your options actually are. The science is evolving fast, and the data is clear: you don’t have to live like this. Let’s take a look at the overlooked patterns and newest discoveries about this underdiagnosed disease.
Most Women Are Told Their Pain Is Normal — It Isn’t
From the women suffering through debilitating cramps to the doctors mislabeling it as “just a bad period,” an article in The Hearty Soul pulls back the curtain on how widespread yet invisible adenomyosis is.1 It presents differently from endometriosis and takes a devastating toll on a woman’s social life, mental well-being, and ability to function day to day.
• Symptoms often mimic other conditions, which causes many women to go undiagnosed — Unlike endometriosis, adenomyosis causes the uterine wall itself to thicken and expand, sometimes doubling or tripling in size. Women describe the pain as knife-like cramping that strikes during menstruation, along with painful sex, bloating, pelvic pressure, and severe bleeding that disrupts quality of life.
There’s a cultural normalization of these symptoms, but just because menstrual pain is common doesn’t mean it’s normal.
• Doctors often dismiss or misinterpret these symptoms, further delaying diagnosis — Gynecologist Dr. Shamitha Kathurusinghe, who points out that many doctors are themselves misinformed: “There’s a lot of misinformation because there’s a lot of misunderstanding that comes from messaging that doctors are getting.” That means women aren’t just being ignored — they’re being actively misled into thinking their symptoms don’t warrant investigation.
• The lack of awareness creates a cycle of isolation and suffering — Many women miss work, cancel plans, and lose relationships because of the unpredictability and severity of their symptoms. Yet they often remain silent out of embarrassment or fear of being labeled “dramatic.”
• Adenomyosis doesn’t always come with symptoms, making it harder to catch early — The condition is often silent for years, only showing up after other reproductive complications arise. But when it does cause symptoms, it mimics endometriosis or fibroids, which complicates diagnosis and treatment decisions.
Younger Women Are Now at Risk — and Doctors Aren’t Catching It
A review published in the Journal of Clinical Medicine revealed just how often adenomyosis is missed or misunderstood in clinical settings.2 The paper compiled data from dozens of high-quality studies to explore how adenomyosis affects everything from fertility to miscarriage risk. The review focused on women of reproductive age and made clear that current diagnostic and treatment approaches are still not consistent, even among specialists.
• Adenomyosis is now being found in much younger women than previously thought — The conventional view has been that this condition primarily affects women in their 40s or 50s, especially those who’ve already had children.
But the paper highlighted that focal forms of adenomyosis — where lesions are isolated rather than spread throughout the uterine muscle — are now increasingly being diagnosed in women in their 30s and even younger. These women often present with fertility problems or abnormal bleeding, but their symptoms are dismissed or misattributed to something else.
• There’s a strong link between adenomyosis and pregnancy complications — Women with adenomyosis have a much higher risk of miscarriage, preterm birth, preeclampsia (dangerously high blood pressure during pregnancy), and delivering babies that are smaller than normal for their gestational age.
These risks are especially pronounced when the adenomyosis is diffuse, meaning it spreads across a wider area of the uterus rather than being confined to one spot. This type of tissue growth interferes with the placenta’s ability to attach and develop normally.
• Even though diagnostic tools exist, global guidelines are still not aligned — so your doctor’s advice may depend on where you live — While some countries are adopting advanced classification systems based on imaging criteria, others still lack a formal system to define or grade adenomyosis severity. That means two women with the exact same symptoms often get completely different diagnoses and treatments depending on which clinic or country they visit.
• The biological explanation lies in how the tissue invades the uterine muscle and disrupts its structure — Researchers believe that tissue from the uterine lining becomes embedded in the muscle wall either through mechanical injury — such as from surgery — or through a faulty junction between the endometrium and the myometrium — the inner and outer layers of the uterus.
Once this tissue is inside the muscle, it thickens and swells with each menstrual cycle, causing inflammation, scarring, and impaired uterine function.
• Several theories explain how adenomyosis starts, but most point to a breakdown in your uterine architecture — One theory, called tissue injury and repair, suggests that repeated damage to the uterine lining causes abnormal healing responses, leading to invasion of the muscle by uterine lining cells.
Another theory proposes that stem cells in the uterus misfire and turn into the wrong kind of tissue, embedding themselves where they don’t belong. In either case, the result is the same: a uterus that’s constantly inflamed, structurally compromised, and metabolically inefficient.

Adenomyosis Isn’t Just Painful — It Leads to Emergency Room Visits
An overview from Johns Hopkins Medicine highlights how adenomyosis becomes medically dangerous, not just inconvenient or uncomfortable.3 While the condition is often brushed off as a heavy period, the article makes clear that some women bleed so much they end up severely anemic, requiring blood transfusions just to restore basic function.
Gynecologic oncologist Dr. Mildred Chernofsky explains that adenomyosis involves tissue that grows into the muscular wall of the uterus and bleeds every month like normal uterine lining. But because it’s trapped in the muscle, it causes inflammation, swelling, and massive blood loss.
• The most severe cases involve hemoglobin levels dropping to life-threatening lows — According to Chernofsky, “I may see patients that bleed until they have a hemoglobin level of 7 grams per deciliter and are extremely anemic.” Normal hemoglobin levels for women range from 12 to 16 g/dL. When blood levels drop this low, women often experience fatigue, dizziness, fainting, shortness of breath, and lightheadedness.
• Most women don’t even realize their uterus has enlarged until the symptoms are advanced — The uterus becomes spongy, heavy, and balloon-like. This bloating feels like constant pressure in your lower abdomen or a sense of fullness that doesn’t go away. Yet during physical exams, doctors often don’t recognize the warning signs unless they specifically palpate the uterus and check for size, shape, and density irregularities.
• Diagnosing adenomyosis still depends heavily on imaging, and MRI remains the most accurate tool — While an ultrasound is usually the first step, it’s not always sensitive enough to pick up on deeper tissue invasion. “MRI provides incredibly high-resolution images and shows us the thickness of the endometrial-myometrial junction,” says Chernofsky. That junction — the boundary where the uterine lining meets the muscle — is usually where the disease starts.
• Adenomyosis often gets confused with two other conditions: endometriosis and fibroids, but the treatments are different — While all three cause pelvic pain and heavy bleeding, they originate in different tissues and require different approaches. Endometriosis involves tissue outside the uterus. Fibroids are benign tumors. Adenomyosis, on the other hand, is diffuse tissue growth inside the uterine wall, and can’t simply be “cut out” the way fibroids sometimes are.
• Surgery is often used as a last resort — Unlike fibroids, adenomyosis tissue spreads throughout the uterus and often has fingerlike projections that invade the muscle. That makes it difficult to remove piece by piece. This means that for women with severe, unrelenting symptoms, removing the uterus becomes conventional medicine’s go-to permanent solution.
How to Stop Feeding the Root Cause of Adenomyosis
If you’ve been dealing with symptoms like heavy bleeding, intense cramping, or a constantly bloated abdomen — and you suspect or know you have adenomyosis — then it’s time to focus on the root of the issue: excess estrogen. Estrogen dominance fuels this disease.4 That includes both the estrogen your body produces and the synthetic or food-based estrogens you’re exposed to without realizing it.
You’re not powerless here. You can start taking control today. The goal is to block what’s driving this disease while rebuilding your energy and restoring balance. If you’re looking to avoid hormonal treatments like birth control pills or you’re looking for alternatives to surgery, these five steps will help you move forward.
1. Cut off the estrogen at the source — If you’re on birth control or hormone replacement therapy, and you’re dealing with adenomyosis symptoms, those drugs are likely making things worse. Synthetic estrogens increase tissue growth inside your uterus.5
You’ll also want to stay far away from plastics, conventional cleaning products, and chemical-laden beauty products — these all contain xenoestrogens, which mimic estrogen in your body. Switch to glass containers, and use natural or homemade personal care and cleaning options.
2. Use natural progesterone to block the damage — Natural progesterone is your anti-estrogen. It doesn’t just relieve symptoms — it actually blocks the effects of both estrogen and cortisol. That’s a powerful combination. But don’t rush into it. If your diet is still holding you back from making energy at the cellular level, progesterone won’t have its full effect. First, rebuild your metabolic foundation.
Once your diet supports mitochondrial energy production, introducing a natural progesterone, as described below, makes a noticeable difference.
3. Fix your metabolism with the right carbs — not fewer — If you’ve been doing keto or low-carb, stop. Shift toward 250 grams of carbs per day, and more if you’re very active. This is what your cells need to make adenosine triphosphate (ATP), the fuel that powers everything from brain function to hormone balance.
Start with white rice and whole fruit. Add well-cooked root vegetables next. Hold off on raw greens, whole grains and beans until your gut is healthy, meaning your bowel habits, bloating, and overall comfort are under control.
4. Filter your toxins, especially vegetable oils — Linoleic acid (LA), the dominant fat in vegetable oils, mimics estrogen, contributing to estrogen dominance. As a result, LA disrupts hormonal balance along with mitochondrial function. Cut out all forms of vegetable oils, including from processed foods, restaurant meals, and even nuts and seeds. Replace them with tallow, grass fed butter, or ghee.
5. Know your prolactin level — Many people believe they’re low in estrogen due to bloodwork, when they actually have high levels in their organs. This is because serum estrogen levels are not representative of estrogen that’s stored in tissues. Estrogen is often low in plasma but high in tissues. Prolactin levels serve as a reliable indicator of estrogen activity, as estrogen directly stimulates your pituitary gland to produce prolactin.
When prolactin levels are elevated, it signals increased estrogen receptor activation, whether from your body’s own estrogen production or environmental exposures to endocrine-disrupting chemicals in microplastics and other pollutants. This relationship is particularly significant when combined with low thyroid function, making prolactin an important marker for identifying hormonal imbalance.
FAQs About Adenomyosis
Q: What is adenomyosis and how is it different from other conditions like endometriosis or fibroids?
A: Adenomyosis is a condition where the tissue that normally lines your uterus grows into the muscular wall of the uterus itself. This causes the uterus to swell and leads to intense cramps, heavy bleeding, and chronic pelvic pain. Unlike endometriosis (where tissue grows outside the uterus) or fibroids (benign tumors), adenomyosis spreads through the uterine muscle and can’t be removed surgically in the same way.
Q: Why do so many women go undiagnosed with adenomyosis?
A: Doctors often misinterpret adenomyosis symptoms or attribute them to other conditions. Symptoms like painful periods, bloating, and fatigue are frequently dismissed as “normal,” especially in younger women. Additionally, imaging tools like ultrasound don’t always catch the disease. MRI is more accurate but less commonly used, so many women are left undiagnosed or misdiagnosed for years.
Q: What are the long-term risks of untreated adenomyosis?
A: Left untreated, adenomyosis often leads to severe anemia from chronic blood loss, requiring emergency care or blood transfusions. It also increases the risk of pregnancy complications, including miscarriage, preeclampsia, and preterm birth. Over time, the ongoing inflammation and uterine damage leads to reduced fertility and significant declines in quality of life.
Q: What is the root cause of adenomyosis and how do I address it?
A: The underlying driver of adenomyosis is excess estrogen, including both natural estrogen and environmental estrogens from plastics, chemicals, and synthetic hormones. To lower your estrogen load, cut out vegetable oils and processed foods, reduce chemical exposures and birth control pills, use natural progesterone and support your metabolism through strategic dietary shifts and mitochondrial repair.
Q: What steps can I take today to start feeling better?
A: Start by eliminating hormone disruptors like synthetic birth control and chemical-laden products. Shift to a higher-carb, whole-food diet to rebuild your mitochondrial function. Add natural progesterone and monitor prolactin levels to get a more accurate picture of your true estrogen burden and hormonal balance.
Linoleic Acid, Mitochondria, Gut Microbiome, and Metabolic Health — A Mechanistic Review
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2025/07/21/linoleic-acid-mitochondrial-damage-metabolic-health.aspx
Analysis by Dr. Joseph Mercola July 21, 2025
Story at-a-glance
- Linoleic acid (LA), a fat found in vegetable oils, accumulates in your tissues and disrupts mitochondrial function, which drains your energy and slows your metabolism
- This fat becomes toxic when oxidized, producing harmful byproducts that damage DNA, enzymes, and the machinery your cells need to generate energy
- Excess LA damages your gut by interfering with colon cell metabolism, harming beneficial microbes, and promoting inflammation linked to insulin resistance and obesity
- LA’s half-life in body fat is about two years, meaning the damage builds up slowly and requires long-term dietary changes to reverse
- Cutting out vegetable oils, eating gut-repairing whole foods, and switching to stable fats like grass fed butter and tallow are key steps to restoring your metabolic health
A century ago, linoleic acid (LA) wasn’t a major part of the human diet. Today, it dominates. Hidden in nearly every processed food and most restaurant meals, this polyunsaturated fat — found in vegetable oils like soybean, corn, and canola — has quietly become the most consumed fat in the modern world.
You’ve likely been told it’s healthy, even essential. But the truth is, LA behaves very differently inside your body than other fats. Unlike saturated fats, it’s chemically unstable. It breaks down easily, especially when exposed to heat, light, or oxygen — turning into toxic byproducts that your body struggles to clear. And unlike fats your body uses for energy, this one gets stored in your tissues and builds up over time, where it quietly interferes with energy production, gut health, and hormone regulation.
If you’ve been dealing with low energy, unexplained weight gain, or insulin resistance, there’s a good chance this hidden ingredient is working against you. Most people don’t realize that the foods they’ve been told are heart-healthy, like certain oils, nuts and packaged snacks, are loading their cells with something they weren’t designed to handle in such high amounts.
In my mechanistic review, published in Advances in Redox Research, I broke down exactly how LA disrupts your mitochondria — the energy engines inside every one of your cells.1 What the research revealed changed how I look at metabolic disease entirely.
Too Much LA Throws Your Metabolism Into Chaos
My paper looks closely at how high intake of LA disrupts mitochondrial function, damages gut balance, and triggers insulin resistance.2 It’s a mechanistic review, meaning it synthesizes a wide range of cellular, biochemical, and metabolic evidence to show exactly how LA breaks energy production inside your cells.
The figure above shows how your mitochondria get thrown off balance when making energy. When there’s too much fuel coming in, it overloads your system and causes a backup at key points called Complex I and II. This leads to reductive stress, where electrons leak out and create harmful byproducts like reactive oxygen species (ROS).
On the flip side, if the system is damaged or can’t keep up, “oxidative stress” occurs, also producing harmful waste. Both situations disrupt energy flow and increase the risk of cell damage. The figure highlights the importance of keeping this process in balance for healthy energy production and overall cellular function.
• LA does damage in two directions at once — I detailed how LA creates both oxidative and reductive stress. Oxidative stress is when your body produces too many free radicals. Reductive stress, by contrast, is when your cells build up too many unused electrons because the mitochondria can’t process them fast enough. This combination wrecks the redox balance that your body depends on to generate clean, efficient energy.
• The damage starts at the mitochondria — your body’s energy centers — LA embeds itself into a special fat called cardiolipin, found in the inner membrane of your mitochondria. Cardiolipin holds energy-generating protein complexes together, kind of like scaffolding. But LA is chemically unstable and easily oxidized.
Once inside cardiolipin, it sets off chain reactions that weaken mitochondrial structure, unravel protein complexes, and reduce adenosine triphosphate (ATP) output — your body’s core energy currency.
• Reductive stress quietly sabotages your energy long before symptoms appear — When your diet contains too much LA — from fried foods, processed snacks, salad dressings, and even “healthy” nuts, pork and chicken — it leads to constant overloading of the mitochondria with electrons.
The problem is that the mitochondrial transport chain can’t keep up. Electrons back up and spill over, generating ROS and worsening oxidative damage. This imbalance is a hidden engine behind fatigue, weight gain, and poor metabolic flexibility.
Why Macronutrient Balance Matters for Redox Health
The figure above illustrates how the balance of protein, carbs, and fat in your diet help protect your mitochondria from the kind of energy overload LA creates. The example in the figure uses a common ratio — about 15% protein, 55% carbs, and 30% fat — to demonstrate how a balanced mix of macronutrients keeps your metabolism running smoothly.
• Carbs and fats take different pathways to get broken down for energy, but both eventually fuel your mitochondria — As they’re processed, they generate molecules that feed electrons into your mitochondria to make ATP. If you eat too much of any one macronutrient — especially fat — it overwhelms the system. Your mitochondria can’t process the excess electrons fast enough, creating a traffic jam that leads to reductive stress and oxidative damage.
• When your diet is more balanced, energy flows through your mitochondria in a steadier way — This reduces the risk of cellular stress and improves metabolic flexibility. This helps explain why even high-fat diets marketed as “healthy” backfire if they’re rich in unstable fats like LA — they push your mitochondria past their limit.
• LA doesn’t just sit in your tissues — it poisons your energy over time — Unlike other fats that your body burns or clears quickly, LA sticks around. It builds up in your fat stores and stays there for years, literally. As noted in my review, the half-life of LA in body fat is estimated to be two years. That means every meal high in LA adds to a long-term problem that your body can’t easily reverse.
• LA pushes your system into dysfunction — While LA is essential in small amounts, excessive intake, over time, floods your mitochondria with reactive molecules. When the supply of electrons from fat breakdown exceeds the mitochondria’s capacity to use them, your energy system crashes from the inside out. The result is poor glucose handling, inflammation, and insulin resistance — what many people chalk up to aging, but is actually preventable damage.

Your Mitochondria Need These Nutrients to Run
The table above shows the essential nutrients your mitochondria need to turn food into usable energy. These include key B vitamins like niacinamide (B3), thiamine (B1), and riboflavin (B2), which act like spark plugs in your cellular engine. They help fuel the chain of reactions that powers ATP production.
• It also includes CoQ10, a compound your body makes but needs more of as you age or if you take statin drugs — CoQ10 helps shuttle electrons inside your mitochondria and reduces oxidative stress.
• Magnesium plays a starring role too — Magnesium helps stabilize ATP and supports hundreds of enzymes involved in metabolism and insulin sensitivity.
• The nutrient amounts listed in the table are general estimates — Your specific needs depend on your diet, health history, and how much stress your system is under. Making sure you get enough of these cofactors helps restore mitochondrial balance and improves how your body handles energy.
Cardiolipin — Your Energy Stabilizer — Gets Hijacked by LA
Cardiolipin isn’t just any fat. It’s unique in structure and key for keeping your mitochondria’s inner membrane stable.
The figure above shows where cardiolipin lives inside your mitochondria and why it matters for energy production. On the left, you see a simplified diagram of a mitochondrion, highlighting its key parts: the outer membrane, inner membrane, the folds called cristae, and the inner space known as the matrix. In the center, the zoomed-in view of the inner membrane points out spots rich in cardiolipin (marked in magenta), especially around the curved edges of the cristae.
These areas help keep the mitochondrial folds stable and support the formation of energy-producing protein clusters. On the right, the figure compares a typical fat molecule with cardiolipin. Unlike regular fats that have two tails, cardiolipin has four, giving it unique properties that help hold proteins in place, keep the membrane flexible, and power essential energy processes. This figure helps explain why cardiolipin is so important for keeping your mitochondria — and your cells — running smoothly.
My review shows how LA infiltrates cardiolipin and makes it highly vulnerable to oxidation. Once oxidized, cardiolipin can’t hold the mitochondrial protein complexes together anymore. This instability ruins the structure needed for ATP production and accelerates cellular aging.
• This process explains why many “healthy” high-fat diets fail over time — While keto or very low-carb diets often seem to work at first by lowering blood sugar, the LA-rich fats they rely on overload your cell “engines.” Breaking down these fats floods your mitochondria with more fuel molecules than they can handle, clogging the energy-production system, slowing ATP creation, and ramping up internal wear-and-tear.
• Once LA oxidizes, it turns into something far more dangerous — The figure above shows how eating too much LA sets off a chain reaction that damages your mitochondria and drains your energy. When you eat a lot of LA, it gets built into the inner membrane of your mitochondria, the part of your cells that makes energy. But LA is fragile. Under stress — especially when your mitochondria are overloaded and energy flow backs up — LA starts to oxidize.
When LA breaks down inside your body, it doesn’t just disappear — it turns into harmful byproducts. One of the worst is called 4-HNE, a sticky, reactive compound that latches onto important parts of your cells like enzymes, DNA, and the machinery inside your mitochondria. Think of it like grease gumming up an engine. It clogs the system that helps your cells make energy. Over time, this damage builds up, draining your energy and stressing your cells even more.
Your Gut Suffers Too, Starting with Your Colon Cells
The figure above shows what happens when your gut microbiome is in balance — and what happens when it’s not. On the left, you see a healthy gut filled with diverse, friendly bacteria that break down fiber into short-chain fatty acids (SCFAs) like butyrate. These compounds feed the cells lining your colon, strengthen your gut barrier, reduce inflammation, and support better blood sugar control. This is how fiber is supposed to work when your gut is healthy.
• LA triggers a cascade that increases inflammation from your gut outward — The right side of the figure tells a different story — one that starts with too much LA in your diet. LA interferes with the ability of colon cells to burn butyrate for fuel, which leaves more oxygen in your gut.
That extra oxygen disrupts the environment, harming helpful bacteria and allowing harmful ones to take over — a condition called dysbiosis. In this inflamed state, the same fiber that normally helps you actually makes things worse by fueling the wrong microbes.
• As dysbiosis deepens, harmful bacteria flourish — They produce toxic byproducts like lipopolysaccharide (LPS), which break through your gut lining and enter your bloodstream. This triggers your immune system, leading to chronic, low-grade inflammation.
Over time, this inflammatory cascade makes insulin resistance worse and raises your risk for problems like fatty liver, obesity, and diabetes. This is known as the fiber paradox — where fiber’s benefits depend entirely on the state of your microbiome.
Insulin Resistance Becomes Inevitable When LA Is High
The table above shows the main tools used to measure insulin resistance and check how well your cells are managing their internal energy chemistry, known as redox balance. One common method is HOMA-IR, a calculation based on fasting insulin and glucose levels that gives a rough idea of how sensitive your cells are to insulin. While it’s convenient for everyday use, it’s not as precise as the gold-standard glucose clamp test, which measures exactly how well your body clears sugar under controlled conditions.
• The table also lists blood markers that reflect how your mitochondria are handling energy — These include ratios like lactate to pyruvate and others that show the balance between NAD⁺ and NADH — a key part of your cell’s energy-making process. When this balance is off, it signals redox stress and early signs of metabolic trouble.
• This is where LA comes in — When your diet is high in LA, it disrupts how your mitochondria produce energy. As that process breaks down, your cells stop responding to insulin the way they should. Your pancreas makes more insulin to compensate, but that only makes things worse. Blood sugar rises, fat starts to build up, and your cells become more inflamed and energy-starved — a downward spiral triggered by too much LA.
Cutting Out LA Helps Restore Your Mitochondria
For more details on the risks of excessive LA intake, read the simplified version of my review. If your energy’s been crashing, your metabolism feels stuck, or your gut hasn’t been right in years, there’s a good chance vegetable oils are part of the problem. You don’t need a lab test to confirm it — just look at what’s in your pantry or what you’ve been eating out.
Getting rid of the LA that’s buried in so many processed foods is the first and most important step to undoing the metabolic damage and giving your cells a chance to function normally again. Here’s what I recommend you do to take back control:
1. Ditch vegetable oils completely — The most direct way to reverse mitochondrial dysfunction is to stop the flood of LA coming in every day. That means eliminating all vegetable oils like soybean, corn, sunflower, safflower, cottonseed, grapeseed, canola, rice bran and peanut oil.
These are hiding in nearly every processed food, packaged snack, and restaurant meal, especially fried foods and dressings. Start reading labels, cook at home more, and treat every elimination as an investment in your energy.
2. Switch to safe fats that don’t damage your mitochondria — Your body needs fat to function — you just need the right kind. Replace those unstable omega-6 fats with stable, saturated fats like grass fed butter, ghee, beef tallow and coconut oil. These fats resist oxidation, don’t overload your mitochondria with electrons, and help restore proper redox balance inside your cells. I use them regularly because they support energy, hormones, and brain health without contributing to inflammation.
3. Eat more foods that repair your gut and feed your colon cells — If your gut’s been compromised by LA, you’ll want to focus on foods that restore the oxygen balance in your colon and support butyrate production. High-quality carbs like sweet potatoes, carrots, squash, and rice are rich in fermentable fibers that fuel this process. But here’s the catch: as mentioned, if your gut is already damaged, throwing in lots of fiber too soon will make symptoms worse. That’s the fiber paradox.
If you’re struggling with bloating, cramping, constipation or loose stools, start by healing your gut first — then introduce fiber-rich foods slowly, in small amounts. Once tolerated, these fibers help reinforce your gut lining, lower inflammation, and recalibrate your immune system. You’ll feel the difference in everything from digestion to energy and mood.
4. Cut back on olive oil, nuts and seeds — even the so-called healthy ones — Nuts and seeds are often seen as health foods, but many, like walnuts, almonds, pecans, sunflower, and pumpkin seeds — are loaded with LA. Even macadamia nuts and olive oil, while lower in LA, are rich in monounsaturated fats that oxidize easily under heat or light.
That oxidation stresses your mitochondria and disrupts energy production. Olive oil is also commonly adulterated with cheaper vegetable oils. If you snack on nut butters or drizzle olive oil over everything, it’s time to rethink those habits.
5. Stay consistent, because LA takes years to clear — This isn’t something you fix in a week. Since LA has a half-life of about two years, it means the fats stored in your tissues now will still affect your mitochondria years from today. But every LA-free meal you eat moves you forward.
Every time you say no to fried foods, chips, or commercial salad dressing, you’re giving your cells a break and slowly offloading the oxidative burden. Think of this like a slow, steady cleanup — each step compounds and helps rebuild your metabolism from the inside out.
FAQs About Linoleic Acid
Q: Why is LA considered harmful if it’s labeled as “heart-healthy”?
A: While LA is essential in small amounts, modern diets overload your body with it, mainly from vegetable oils. In excess, LA embeds itself in your mitochondria, oxidizes, and creates toxic byproducts that damage energy production, promote inflammation, and drive insulin resistance.
Q: What are the signs that LA is damaging my metabolism?
A: If you experience chronic fatigue, weight gain, blood sugar issues, gut problems, or difficulty losing fat despite a healthy diet, LA could be a hidden factor. It accumulates in your fat tissue, disrupts mitochondrial function, and lingers in your body for years, slowing energy output and triggering inflammation.
Q: How does LA affect gut health?
A: LA interferes with the metabolism of colon cells, which alters the gut environment by raising oxygen levels, harming beneficial microbes and favoring the growth of harmful bacteria. This shift leads to dysbiosis and increases the production of inflammatory compounds that breach your gut lining and enter your bloodstream, contributing to systemic inflammation.
Q: What foods should I avoid to lower my LA intake?
A: Steer clear of vegetable oils like soybean, corn, safflower, sunflower, and canola oils. Also limit high-LA foods such as processed snacks, fried foods, salad dressings, and even chicken, pork, nuts, seeds, and olive oil.
Q: How long does it take to get LA out of my body?
A: LA has a half-life of about two years, so it takes time to clear. However, every LA-free meal you eat helps reduce your oxidative burden, improve mitochondrial function, and restore metabolic health day by day.

Analysis by Dr. Joseph Mercola May 10, 2025
STORY AT-A-GLANCE
- New research shows inflammation directly influences mood and behavior by sending chemical signals that activate anxiety circuits in the brain, helping to explain emotional aftereffects of illness
- Specific inflammatory cytokines stimulate neurons in brain regions responsible for processing fear, while anti-inflammatory signals calm these same neural pathways
- Scientists discovered that certain immune molecules function like neurotransmitters in the brain, influencing social behavior and emotional states independently of inflammation
- Blocking inflammation incorrectly backfires; it triggers more intense anxiety as the body produces additional inflammatory messengers that overstimulate fear circuitry
- Managing inflammation-related mood issues requires reducing linoleic acid (LA) intake from vegetable oils, supporting mitochondrial function, getting safe sun exposure, avoiding alcohol and monitoring emotional symptoms after illness
After a physical illness, emotional aftershocks are more common than most people realize. Mood swings, irritability and even social withdrawal often surface without warning — and they don’t always go away when the fever breaks or the rash fades. These shifts are frequently dismissed as psychological or stress-related, but there’s more going on under the surface.
Emerging science is redefining how we understand these post-illness changes. Rather than being side effects of recovery, they appear to be part of a complex feedback loop between your immune system and your brain. It’s not just about fighting infection. Your body is sending signals that shape how you feel, how you think and how you connect with others.
For years, the biological link between the immune response and emotional state was a mystery. Doctors observed the patterns but lacked a clear explanation for why recovering patients often reported feeling emotionally unwell. That’s beginning to change.
Recent research is uncovering exactly how immune activity interacts with brain circuits involved in mood and behavior, offering new clues — and new hope — for addressing anxiety, depression and social disconnection at the source.
A set of studies, published in Cell in April 2025, offers a detailed look at this immune-brain connection.1,2 These findings move us beyond theory and into practical understanding of how immune molecules affect your emotional wiring in real time.
Inflammation Hijacks Your Brain’s Anxiety Center
The first study investigated how inflammation affects anxiety by mapping how immune molecules called cytokines interact with brain circuits.3 The researchers focused on two inflammatory signals and how they stimulated neurons in a region of the brain responsible for processing fear and emotional memories. In animal models, the team looked at how changes in immune activity led to shifts in anxiety-related behaviors.
• Researchers identified brain cells that react to both pro- and anti-inflammatory signals — The key discovery was that certain brain cells respond to both types of immune messengers. These cells are constantly listening for cues. If the message is inflammatory, anxiety circuits rev up; if the message is anti-inflammatory, those same circuits calm down. Your mood, in other words, is closely tied to which immune signals your brain is getting at any given time.
• The findings explain why you feel more anxious during or after illness — When inflammatory cytokines rose, mice became more anxious. They avoided open spaces, explored less and showed clear signs of being on edge. Even more surprising, when researchers tried to block these inflammatory signals, it made things worse. The body responded by producing even more inflammation, which overstimulated the brain’s fear circuitry.
• Blocking inflammation the wrong way triggered rebound anxiety — In the study, interfering with inflammatory signaling didn’t reduce anxiety — it backfired. The body overcorrected by flooding the system with more inflammatory messengers, creating even more excitability in fear-processing neurons. This highlights how delicate the system is and why simply trying to “shut off” inflammation won’t work without understanding the underlying balance.
Calming Signals Work Through the Same Brain Pathway
The same brain cells that react to inflammatory signals also respond to anti-inflammatory cues. When those calming signals were increased, the anxious behavior disappeared. The mice became calmer, more balanced and less reactive to their environment. These results show that your immune system has its own internal checks and balances — you just have to support them.
• One calming molecule suppresses anxious brain activity — A specific anti-inflammatory signal works like a brake for your brain’s fear response. When this molecule interacts with the neurons in your brain’s anxiety center, it lowers their activity. That makes them fire less often, which slows the brain’s anxiety feedback loop. In other words, your brain becomes less hyperreactive and more emotionally stable.
• These immune messengers act instantly — Your immune system sends out real-time signals that shift your emotional state within minutes. That’s why anxiety often feels like it comes out of nowhere. A spike in inflammation, whether from an infection, injury or stress, changes how your brain behaves almost immediately.
• Fear-processing cells get stuck in overdrive — When inflammatory messengers dominate, the neurons in your brain’s fear center become overly excitable. They start firing too often and too intensely, feeding a loop of anxiety and worry. This makes it harder for your body’s natural calming systems to keep up. Your stress response becomes harder to shut off.
• The same neurons receive both calming and fear signals — The exact same brain cells can be told to panic or to relax, depending on which immune molecule they hear from. If your system is inflamed, those calming signals get drowned out. But if you support your immune balance, those neurons switch back to a more stable, regulated state.
• This is physical, not just psychological — Anxiety isn’t just mental. It’s physical. It’s rooted in your biology, your immune response and the real-time signals your body is sending to your brain. When inflammation is high, your emotional resilience takes a hit. When it’s balanced, your mood stabilizes.

Cytokines Boost Social Behavior by Acting Like Brain Chemicals
The second study focused on a lesser-known cytokine and how it interacts with specific brain receptors to influence social behavior.4 Researchers wanted to know which immune-related signals show up in the brain and how they affect behavior when triggered. Instead of focusing on how these signals trigger inflammation, the team explored their role as brain messengers — working more like mood-regulating chemicals to shift behavior in real time.
• Researchers identified a brain signal that increases sociability and curiosity — A specific chemical message activates a part of the brain responsible for social behavior. When this signal was triggered, mice that usually avoided others and repeated the same actions over and over began behaving more normally.
They explored their surroundings, showed interest in new mice and became more socially engaged. According to the researchers, this signal helped restore a more natural pattern of social connection.
• This chemical signal is made inside the brain, not just by the immune system — In a major discovery, researchers found that this social signal isn’t just produced by immune cells; it’s also made directly by neurons inside the brain. That’s a big deal, because it puts this molecule in the same category as familiar brain chemicals like serotonin and dopamine. It’s not just reacting to the immune system — it’s helping control mood and behavior from within.
• Your brain and immune system use the same language to control behavior — This finding challenges the old belief that immune signals only work outside the brain. In reality, the brain uses some of the exact same molecules your immune system does — just in a different context.
These shared messages help manage emotional behavior, including how connected, curious or socially withdrawn you feel. In this case, boosting the signal helped correct withdrawn behavior in mice genetically inclined toward social avoidance.
• Cytokines influence emotional state and behavior without needing to enter the brain — One of the most important takeaways from the research is that immune molecules don’t have to cross the blood-brain barrier to affect how you feel. The research showed that cytokines act on brain areas that already receive immune signals.5
These findings are part of a broader effort to understand how your brain and immune system work together — and sometimes against you — to shape your mood.
• Scientists are also questioning how inflammation impacts the blood-brain barrier itself — A lingering question could hold the key to better treatments: Does chronic inflammation weaken the blood-brain barrier, making it more permeable to damaging substances? If so, then long-term inflammation wouldn’t just influence mood temporarily; it could change how vulnerable your brain is to future damage.6
What to Do About Chronic Inflammation That Alters How Your Brain Processes Mood and Behavior
If your anxiety, mood swings or social withdrawal feel worse after getting sick — or seem to come out of nowhere — it’s time to take a closer look at the root cause: chronic inflammation. You don’t fix this by numbing symptoms. You fix it by restoring balance to your immune system and protecting your brain’s delicate communication circuits.
The goal is to stop the runaway signaling that hijacks your emotional centers and rewires your behavior from the inside out. These five steps target the biological triggers, including cytokine signaling, mitochondrial stress and brain inflammation, so you start feeling like yourself again.
1. Cut linoleic acid (LA) down to under 5 grams per day — ideally below 2 — If you only do one thing, make it this. LA in vegetable oils drives inflammation like gasoline on a fire. It hides in nearly every processed food: restaurant meals, sauces, chips, crackers, even “healthy” organic snacks. Swap all vegetable oils for healthier fats like grass-fed butter, ghee or tallow.
Stay away from olive and avocado oil, as they’re often cut with cheaper vegetable oils and still too high in monounsaturated fat, which causes similar mitochondrial dysfunction. I recommend tracking your LA intake for a few days using a free online food tracker. You’ll be shocked by what you uncover.
2. Support your mitochondria by giving them the fuel they actually need — Your mood is tied directly to how much energy your cells produce. Cytokines disrupt this energy flow, which leaves you feeling drained, foggy or emotionally reactive. To repair that, you need to restore production of adenosine triphosphate (ATP), your body’s main energy currency that your cells need to survive and repair.
Start by increasing your carbohydrate intake with easy-to-digest sources like fruit juice with pulp, white rice and whole fruit. If you have unbalanced gut bacteria, or dysbiosis, avoid fiber, including whole grains, until your gut is healed. Ultimately, most adults need about 250 grams of healthy carbs daily. Starving your mitochondria will only prolong the problem.
3. Boost your anti-inflammatory signals naturally with sun exposure — Sunlight helps your cells produce energy more efficiently and triggers your body to make key anti-inflammatory molecules. It also helps regulate mood through melatonin and vitamin D production. But don’t just sunbathe randomly.
The safest and most effective exposure happens after you’ve eliminated seed oils from your diet for at least six months. Until then, stick to morning and late-afternoon light — no harsh midday sun.
4. Avoid alcohol, as it destroys mitochondrial function and inflames your brain — Alcohol is a metabolic poison. Even small amounts disrupt mitochondrial energy production and increase oxidative stress in the brain. The idea that moderate drinking is protective was based on flawed studies. Don’t let marketing override your biology.
5. Watch for delayed emotional symptoms after illness and adjust early — If you’re someone who experiences mood swings after getting sick, or during stressful immune events like a dental procedure or vaccine, start tracking your mood in a journal. Note when symptoms begin, how long they last and what symptoms show up, like irritability, social withdrawal or fatigue.
This helps you link emotional shifts to immune activity and gives you a clear signal when it’s time to double down on your recovery strategies.
The earlier you respond, the faster you recover. When your immune system is in balance, your brain calms down. You think more clearly, connect more easily with others and feel more like yourself again.
FAQs About Inflammation and Mood
Q: How does inflammation affect your mood and behavior?
A: Inflammation sends chemical messengers called cytokines into your bloodstream, some of which directly activate anxiety circuits in your brain. These signals make you feel anxious, withdrawn or emotionally unstable, especially after illness or during immune system flare-ups.
Q: What role do immune signals play in emotional regulation?
A: Some immune signals increase anxiety by overstimulating the part of your brain that processes fear. Others send calming messages to those same brain cells, helping reduce anxious behavior. Your emotional state depends on which of these signals is stronger at any given time.
Q: Can immune signals influence social behavior too?
A: Yes. One specific immune signal was shown to increase social interest and reduce repetitive behavior in mice that typically avoided interaction. What makes it unique is that it’s also produced by brain cells, not just the immune system, so it acts more like familiar brain chemicals such as serotonin or dopamine.
Q: What’s the connection between chronic illness and mood swings?
A: New research shows that mood changes following infections or autoimmune episodes are the result of immune-brain cross talk. Inflammatory cytokines activate specific brain circuits almost immediately, reshaping how you process fear, emotion and social interaction.
Q: What helps lower cytokine-driven mood issues?
A: Start by removing vegetable oils and processed foods that drive inflammation. Support cellular energy with digestible carbs like fruit and white rice. Get safe sun exposure to activate your body’s anti-inflammatory pathways and avoid alcohol, which impairs mitochondrial function and inflames your brain.
