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.
Insulin Resistance — What It Is and How to Fight It

Story at-a-glance
- Insulin resistance occurs when cells don’t respond properly to insulin, causing elevated blood sugar and increased insulin production that leads to diabetes, heart disease, and cancer
- Diet significantly impacts insulin sensitivity, with processed foods containing linoleic acid (found in seed oils) promoting inflammation and worsening insulin resistance
- Mitochondrial dysfunction plays a key role in insulin resistance, as these cellular “power plants” become less efficient when overloaded with linoleic acid and refined sugars
- Doctors measure insulin resistance using HOMA-IR (a simple blood test) or, less commonly, the more expensive hyperinsulinemic-euglycemic clamp method
- Improving insulin sensitivity involves eating whole foods, consuming 200 to 350 grams of healthy carbohydrates daily, avoiding processed foods, choosing healthy fats and exercising regularly
Have you ever wondered why some people gain weight easily or struggle with high blood sugar? It could involve insulin resistance. This happens when your body’s cells don’t respond well to insulin, a hormone that controls your blood sugar. If left unchecked, it leads to serious issues like Type 2 diabetes, heart disease, and even some cancers.
In the video above, Dr. Peter Attia, who received his medical degree from Stanford and completed surgical residency at the eminent Johns Hopkins Hospital, interviews Dr. Ralph DeFronzo, a distinguished diabetes researcher and clinician.1 They discuss what insulin resistance is and how it impacts specific organs — along with how to accurately check if you have it. But here’s the good news: you can improve your insulin sensitivity with simple changes, especially to your diet.
What Is Insulin Resistance?
Insulin is like a key that unlocks your cells so they can take in sugar (glucose) from your blood. When you eat, your body turns food into sugar, which enters your bloodstream. Insulin then moves that sugar into your cells to give you energy. But when you have insulin resistance, your cells don’t respond well to insulin.
It’s like the locks on your cells are rusty — the key doesn’t work right. As a result, sugar builds up in your blood, and your body pumps out more insulin to try to fix it. Over time, this leads to high blood sugar and too much insulin, which isn’t good for you.
• Why should you care? Insulin resistance isn’t just a small problem — it’s linked to serious health risks. If your cells can’t use insulin properly, you could face:
◦ Type 2 diabetes — Too much sugar in your blood damages your body over time.
◦ Heart disease — High insulin levels harm your blood vessels.
◦ Certain cancers — Some studies suggest insulin resistance might increase cancer risks, like breast or colon cancer.
The bright side? You can fight back by understanding what’s going on and making smart choices, like tweaking your diet.
• How does diet improve your insulin sensitivity? What you eat has a significant impact on how well your body uses insulin. Let’s break it down and see how your diet either helps or hurts your insulin sensitivity.
• What’s the deal with linoleic acid (LA)? One important thing to watch is a fat called linoleic acid (LA). You find it in seed oils that are common in processed foods like chips, fried snacks, and baked goods. A little LA is OK, but too much harms your cellular energy production and causes inflammation — think of it as your body getting irritated inside.
This irritation makes insulin resistance worse. To help your body out, cut back on these processed foods and go for healthier fats instead, like ghee, tallow, and grass fed butter.
• How does redox balance fit in? Another piece of the puzzle is something called redox balance. Imagine it as a seesaw in your cells that keeps everything working smoothly. When this seesaw tips out of balance, it interferes with how your cells use insulin. Eating foods packed with antioxidants — like colorful fruits and veggies — helps keep that seesaw steady and supports your insulin sensitivity.
Insulin Resistance — A Problem with Your Cells’ Energy Factories
Now, let’s dig a little deeper. Insulin resistance isn’t just about sugar — it’s tied to how your cells make energy. Here’s what you need to know.
• What causes insulin resistance? Your cells have tiny power plants called mitochondria that turn sugar into energy. When these power plants don’t work right, it’s called mitochondrial dysfunction. Think of it like a factory with broken machines — it can’t keep up. This interferes with how your cells use insulin, leading to insulin resistance.
Seed oils play a big role here, as LA is a mitochondrial poison that compromises your cellular energy production. Once rare, seed oils are now everywhere in processed foods — like baked goods, frozen meals, and salad dressings. Refined sugar also plays a role.
Unlike natural sugars in fruits that come with fiber and nutrients, refined sugars offer no nutritional benefits and significantly increase health risks. Eating too much refined sugar overworks your mitochondria, making them less efficient. Over time, this tips your body toward insulin resistance.
• How does redox imbalance make it worse? There’s also something called redox imbalance. Inside your cells, there’s a balance between helpful and harmful particles. Too much refined sugar or unhealthy fats (like LA) throw this off, creating stress that damages your mitochondria. It’s like overloading a circuit — things start to break down. This stress makes it harder for insulin to do its job, pushing you closer to insulin resistance.
• Why does this matter for your health? When your mitochondria struggle, insulin resistance leads to bigger problems:
◦ Type 2 diabetes — Your blood sugar stays high because cells can’t use it.
◦ Heart issues — Damaged energy production affects your heart and vessels.
◦ Brain health — Some experts even call Alzheimer’s “Type 3 diabetes” because of insulin resistance in the brain.
The fix? Diet and lifestyle changes help your mitochondria work better and improve your insulin sensitivity.

Using HOMA-IR to Spot Insulin Resistance Early
One of the simplest and most reliable ways to gauge how well your body handles insulin is through a test called HOMA-IR, short for Homeostatic Model Assessment of Insulin Resistance.
Unlike other cumbersome procedures, HOMA-IR only requires two basic blood tests done first thing in the morning before you eat: one for fasting glucose and one for fasting insulin levels. These tests are relatively affordable and widely available at most labs. Armed with those numbers, you then plug them into a straightforward formula to get your HOMA-IR score:
HOMA-IR = (Fasting Glucose in mg/dL × Fasting Insulin in μU/mL) / 405
The goal is to see just how hard your body is working to keep your blood sugar in check. If your HOMA-IR is higher than 1.0, it’s generally a warning sign that you might be edging into insulin resistance territory. The lower your score, the better your insulin sensitivity, so even values that hover around 1.0 deserve some attention if you’re looking to optimize your health.
The beauty of HOMA-IR lies in its simplicity. You don’t have to schedule multiple visits or endure complicated test procedures. You wake up, don’t eat or drink anything other than water, head to the lab for a quick blood draw, and get your results shortly after. Alternatively, Mercola Labs has a dried blood spot card that allows you to prick your finger after you get up and put drops of blood on a card and mail it in, which is far more convenient and less expensive.
It’s a far cry from the gold-standard research method known as the euglycemic hyperinsulinemic clamp, introduced by DeFronzo in 1979, where participants are hooked up to an IV for hours. In the clamp procedure, researchers administer insulin and glucose simultaneously, measuring exactly how much glucose is needed to keep blood sugar at a steady level when insulin is being pumped in.
Although extremely accurate, this process is time-consuming and inconvenient, making it unfeasible for routine monitoring in a clinical or everyday setting. It’s also pricey, costing an average of $1,000 for a single test. Consequently, it’s primarily confined to research settings.
That’s why HOMA-IR remains such a powerful tool in both scientific research and personal health management: it balances accuracy with practicality. It’s not a perfect snapshot — no single test can capture the full complexity of your metabolic health — but it’s solid enough to highlight when your body starts resisting insulin’s signals.
I found it shocking that both DeFronzo — who invented the euglycemic hyperinsulinemic clamp test — and Attia, one of the smartest biohackers out there, failed to acknowledge that the HOMA-IR test is the pragmatic, simple, inexpensive way to measure insulin resistance, as opposed to the test that DeFronzo invented.
By using the HOMA-IR test and catching those early warnings, you can make diet and lifestyle tweaks long before you slip into more serious issues. For most people, if your HOMA-IR creeps above 1.0, it’s time to pay closer attention to factors like sugar intake, seed oils, plastic exposure, and gut health.
Over time, as you dial in these elements of your routine, you can retest HOMA-IR and see if your score drops. That direct feedback can be a potent motivator to keep you on track toward a healthier, more energetic life.
Practical Tips to Boost Your Insulin Sensitivity
Ready to make some changes? Here’s how to improve your insulin sensitivity through diet:
1. Eat more whole foods, including healthy carbs — Carbohydrates play a key role in supporting your mitochondrial function. Glucose, derived from carbohydrates, serves as your cells’ preferred fuel source for energy production. Instead of restricting carbs, focus on eating 200 to 350 grams of the right types, such as whole fruits, root vegetables and well-tolerated whole grains. If you have dysbiosis, avoid fiber until your gut is healed.
2. Cut back on processed foods — Avoid processed foods — they’re full of LA-rich seed oils and refined sugars that drive inflammation and worsen insulin resistance.
3. Pick healthy fats — Swap out canola, corn, and soybean oil for healthy fats like grass fed butter, tallow, and ghee.
4. Move your body — Exercise isn’t food, but it helps your cells use insulin better. A daily walk does wonders.
Small steps like these help your body respond to insulin again and lower your health risks. Start small: swap store-bought baked goods for fresh fruit or take a daily walk outside. You can make a big difference in your health with these positive changes.
FAQs — Your Top Insulin Resistance Questions Answered
Q: What foods help insulin sensitivity?
A: Prioritize healthy carbohydrates like fruit and root vegetables, and avoid seed oils high in linoleic acid. Skip processed foods high in refined sugar and unhealthy fats.
Q: How do doctors check for insulin resistance?
A: They often use HOMA-IR, a simple test that involves fasting blood sugar and insulin levels. While the hyperinsulinemic-euglycemic clamp is considered the gold standard, HOMA-IR is less expensive and more practical for routine use.
Q: Can exercise fix insulin resistance?
A: Yes, moving your body helps your cells use insulin better. Even daily walks help improve insulin sensitivity.
Q: What are the long-term health risks associated with insulin resistance?
A: Insulin resistance is linked to serious conditions like Type 2 diabetes, heart disease, and even some cancers. Addressing insulin resistance through diet and lifestyle changes is important for preventing these chronic illnesses.
How Molecular Hydrogen Fights Inflammation and Reverses Fatty Liver Disease

Analysis by Dr. Joseph Mercola December 28, 2025
Story at-a-glance
- Molecular hydrogen acts as a selective antioxidant that targets only harmful free radicals, helping to calm inflammation without disrupting essential cellular signaling
- Research discussed by Tyler LeBaron shows that hydrogen therapy reverses non-alcoholic fatty liver disease (NAFLD) by restoring mitochondrial function and reducing fat accumulation in the liver
- Hydrogen’s small molecular size allows it to penetrate deep into cells, including mitochondria and your brain, where it supports energy production and reduces oxidative stress
- Short, pulsed use of hydrogen — through hydrogen-rich water or inhalation — produces stronger benefits than continuous exposure, improving your body’s ability to adapt and heal naturally
- Using hydrogen alongside simple lifestyle changes such as limiting seed oils, eating nutrient-dense foods, and getting daily sunlight enhances liver health, boosts energy, and supports long-term metabolic balance
Non-alcoholic fatty liver disease, or NAFLD, has become one of the fastest-growing metabolic disorders worldwide, quietly affecting millions of adults who often feel perfectly healthy. Unlike alcohol-related liver damage, this condition stems from excess fat stored in your liver due to modern lifestyle factors — poor diet, inactivity, and chronic stress — that overwhelm your body’s ability to manage oxidative stress.
What makes it so insidious is that most people have no idea it’s happening until significant damage has already occurred. You might notice subtle signs first — low energy, brain fog, or mild abdominal discomfort — but these are easy to dismiss. Beneath the surface, your liver is struggling to keep up with the flood of inflammation and metabolic waste that builds when your cells are out of balance.
Left unchecked, this dysfunction doesn’t stop at your liver. It sets the stage for diabetes, heart disease, and even neurodegenerative disorders, all rooted in the same cellular breakdown. Addressing that root cause requires more than symptom relief — it demands restoring cellular balance where the problem begins. That’s what makes molecular hydrogen so remarkable.
As Tyler LeBaron, MSc., Ph.D., founder of the Molecular Hydrogen Institute, explains on Chemaine’s Model Health podcast, this simple molecule helps your body repair itself by regulating oxidative stress and supporting mitochondrial energy production.1
I’ve interviewed LeBaron myself, and as he explains, molecular hydrogen acts as a precision tool for inflammation control, protecting healthy cells while allowing your immune system to function as designed. By understanding how molecular hydrogen rebalances these core cellular processes, you gain a powerful strategy for protecting your liver — and your overall health — from the ground up.
Hydrogen Restores Cellular Balance and Protects Against Inflammation
In the discussion, LeBaron explains that molecular hydrogen (H2) is far more than a simple antioxidant. Unlike conventional antioxidants that indiscriminately neutralize free radicals, hydrogen works selectively. It targets the most harmful species — especially hydroxyl radicals — without disturbing the free radicals your body actually needs for signaling and immune defense. This precision allows it to calm inflammation without suppressing necessary repair processes.
• Hydrogen therapy has profound protective effects during stroke and cardiac injury — In the 2007 Nature Medicine study that inspired LeBaron’s research path, rats exposed to a stroke model were given low concentrations of hydrogen gas (about 2%).2
This small dose reduced brain injury dramatically by limiting oxidative damage. LeBaron notes that this finding ignited the entire field of hydrogen research, as it showed hydrogen could be administered safely and still exert measurable, therapeutic effects on living tissue.
• Molecular hydrogen has been studied as a treatment for NAFLD — LeBaron describes research showing that hydrogen-rich water reduced fat accumulation in animal models of fatty liver. Low-dose hydrogen water offered minimal benefit, but higher concentrations significantly improved liver function and reduced inflammation. Follow-up clinical trials mirrored these results in humans, showing measurable drops in liver fat and improved body composition within weeks.
• Participants with metabolic syndrome saw major after consuming hydrogen water three times daily — This group — characterized by abdominal obesity, high triglycerides, and insulin resistance — experienced reduced oxidative stress and enhanced mitochondrial efficiency, along with improvements in body fat, lipid profiles, and inflammation markers.
• Hydrogen’s effects involve fine-tuned control of oxidative and inflammatory pathways — Hydrogen activates the body’s master antioxidant switch. When turned on, this switch increases the production of protective enzymes like glutathione and superoxide dismutase — your cells’ natural shields against oxidative stress.
At the same time, hydrogen inhibits a signaling molecule that triggers chronic inflammation. The result is not immune suppression but recalibration: inflammation quiets where it’s excessive yet stays strong when needed for healing.
• Hydrogen’s selective action helps prevent cell death caused by oxidative overload — This process is known as apoptosis. In studies where cells were stressed with toxins or lack of oxygen, hydrogen exposure reduced apoptosis rates dramatically.
This protective effect stems from its ability to neutralize unstable molecules that attack DNA, proteins, and cell membranes. By eliminating only these harmful radicals, hydrogen spares beneficial molecules like nitric oxide, which are vital for blood flow and immune communication.
Hydrogen Therapy Is Easy to Use and Safe, Even at High Doses
Tablets that produce hydrogen when dropped into water create a cloudy, effervescent drink. LeBaron explains that the cloudiness shows active hydrogen gas in solution and that drinking it while still cloudy ensures the highest dose.
Room temperature water dissolves hydrogen best, and consuming it immediately after the tablet finishes dissolving maximizes benefits. Unlike other therapies that require IV drips or expensive devices, hydrogen offers an accessible, nontoxic option you can use daily at home.
• The molecule’s small size gives it a unique advantage — It diffuses through cell membranes, crosses your blood-brain barrier, and reaches mitochondria directly. LeBaron points out that hydrogen’s bioavailability is unmatched — it penetrates areas where larger antioxidants, such as vitamins C or E, can’t go.
Once inside your mitochondria — the energy factories of your cells — it helps restore normal energy production. This mitochondrial support is key for chronic fatigue, liver disease, and metabolic decline, all of which share a common thread: energy dysfunction caused by oxidative stress.
• Hydrogen’s anti-inflammatory benefits extend beyond your liver — They also support neurological, cardiovascular, and immune function. LeBaron reports that animal and human studies reveal improvements in cognitive performance, reduced anxiety, and faster recovery after injury.
Hydrogen’s adaptogenic nature — its ability to help your body adapt to stress — means it raises antioxidant defenses when needed but steps back when balance is restored. This prevents the “overcorrection” that often happens with high-dose antioxidant supplements.
• For those living with chronic pain, fatigue, or inflammatory conditions, hydrogen therapy represents a way to take back control — It doesn’t replace a healthy lifestyle, but it enhances your body’s ability to repair itself.
When paired with other energy-supportive habits like adequate sunlight, nutrient-rich foods, and reduced seed oil intake, hydrogen accelerates recovery and resilience. LeBaron’s research underscores a key point: the route to healing chronic inflammation isn’t suppression — it’s restoration of balance at the cellular level.
• Hydrogen works because it aligns with how your body naturally regulates stress and energy production — Unlike drugs that target one pathway or symptom, hydrogen communicates with your body’s own systems, teaching them to recalibrate. This precision makes it effective for a wide range of issues, from NAFLD and cardiovascular damage to neuroinflammation and fatigue.

Less Is More When It Comes to Benefits
It’s tempting to think that more hydrogen equals faster healing, but in this case, less is often more. Hydrogen therapy works best when it’s pulsed — periods of exposure followed by periods without. This intermittent approach enhances your body’s adaptive response and prevents tolerance, where your cells stop reacting as strongly.
• Pulse your intake — Drink hydrogen-rich water at specific times instead of sipping it throughout the day.
• Time your inhalation — Keep hydrogen gas sessions short (one to three hours) rather than continuous exposure.
• Take breaks — Give your body several hours each day without hydrogen supplementation so it recalibrates its signaling pathways.
• Not all hydrogen products deliver therapeutic doses — Measuring hydrogen concentration accurately requires gas chromatography, something most companies don’t do.
So, for those using molecular hydrogen at home, you’ll need to be cautious about product claims. The most reliable way to verify claims is to cross-reference methods verified in clinical trials. These include certain hydrogen-generating tablets that have been shown to produce therapeutic levels of hydrogen.
When used with intention, molecular hydrogen is one of the simplest, safest, and most effective ways to calm inflammation, repair your liver, and restore energy from the inside out. Your body already knows how to heal — hydrogen just gives it the spark to remember how.
How to Use Molecular Hydrogen to Heal Inflammation and Fatty Liver
If you’re dealing with chronic inflammation, fatigue, or a sluggish liver, it’s not just about easing discomfort — it’s about restoring energy at the cellular level. When oxidative stress overwhelms your system, your cells lose the ability to generate clean energy, setting the stage for insulin resistance and liver fat buildup.
Molecular hydrogen helps reset that system by teaching your body how to regulate inflammation, repair mitochondria, and restore balance from the inside out. Here’s how to make it work for you — safely, effectively, and sustainably.
1. Start with hydrogen-rich water daily to restore cellular balance — Drop one hydrogen tablet into a glass of room temperature water and drink it immediately after the tablet fully dissolves and the water turns cloudy. That cloudy look signals the presence of active hydrogen gas — the component that triggers healing.
If you’re dealing with liver inflammation, brain fog, or chronic fatigue, take hydrogen-rich water two to three times per day, at least an hour apart. This rhythmic “pulsing” gives your cells time to adapt and strengthens their internal defense systems rather than overwhelming them.
2. Use the right delivery method and timing — Hydrogen-rich water made from properly formulated tablets offers the most consistent and convenient way to supplement. Drink it immediately after preparation — don’t let it sit, or the hydrogen gas will dissipate.
If you prefer inhalation, keep sessions short — around one to three hours — rather than continuous exposure. Research and experience from experts like LeBaron show that pulsed use leads to better long-term results, as your cells respond more effectively when hydrogen is introduced intermittently rather than constantly.
3. Combine hydrogen therapy with habits that lower oxidative stress — Even the most powerful molecule can’t offset daily damage from poor diet, alcohol, and inactivity. Limit linoleic acid (LA) from seed oils to less than 3 grams per day and avoid alcohol — it’s a mitochondrial toxin that directly impairs liver recovery. Get natural sunlight exposure daily to recharge your cellular energy production. Pair hydrogen with these habits, and you’ll multiply its benefits, improving liver function, focus, and energy throughout the day.
4. Support your liver’s energy metabolism instead of depriving it — Starving your body with restrictive diets or extended fasting weakens mitochondrial function — the very system hydrogen helps heal. Focus on feeding your liver with healthy carbohydrates to maintain steady energy and promote fat metabolism — about 250 grams daily.
If your digestion is weak, start with easy-to-digest options like fruit and white rice before adding more fiber-rich whole foods. Once your liver has the energy and nutrients it needs, hydrogen will amplify its repair and detox capacity more efficiently.
5. Use hydrogen before mental or physical stress — Timing hydrogen intake around stressful events — such as before exercise, travel, or emotionally intense days — helps significantly reduce oxidative stress buildup. Drink hydrogen-rich water about 30 minutes before those stressors to buffer free radical surges. This approach gives your body extra resilience when it needs it most, improving energy, focus, and recovery afterward.
FAQs About Molecular Hydrogen
Q: What makes molecular hydrogen different from other antioxidants?
A: Unlike conventional antioxidants that indiscriminately neutralize all free radicals, molecular hydrogen targets only the most harmful species — particularly hydroxyl radicals — while preserving the beneficial ones your body needs for normal signaling and immune function. This selective action reduces inflammation without disrupting vital repair processes, making it safer and more effective for long-term use.
Q: How does molecular hydrogen help reverse fatty liver disease?
A: Hydrogen works by restoring balance at the cellular level. It reduces oxidative stress, calms inflammation, and improves mitochondrial energy production — the root causes of fat buildup in the liver. Studies show that hydrogen-rich water decreases liver fat and inflammation, while improving metabolism and body composition within weeks.
Q: What’s the best way to take molecular hydrogen?
A: Hydrogen-rich water made from properly formulated tablets is the most reliable and convenient delivery method. Drink it as soon as the tablet fully dissolves and the water turns cloudy — this ensures you’re getting active hydrogen gas.
Q: Is more hydrogen always better?
A: No. Hydrogen therapy works best when used intermittently or “pulsed.” Your body responds more effectively when hydrogen exposure alternates with rest periods. Drink it at specific times rather than continuously throughout the day, and limit inhalation sessions to one to three hours. This pattern enhances your body’s adaptive response and prevents tolerance.
Q: What lifestyle habits make hydrogen therapy more effective?
A: Hydrogen works best when paired with supportive lifestyle choices. Limit LA from seed oils to under 3 grams per day, avoid alcohol, and get daily sunlight exposure to boost mitochondrial energy production. Eat nourishing carbohydrates to keep your liver fueled, and use hydrogen before stressful events or exercise to reduce oxidative stress. These habits amplify hydrogen’s ability to restore energy, calm inflammation, and protect your liver and brain.

Analysis by Dr. Joseph Mercola November 08, 2025
Story at-a-glance
- Compounds in the essential oil of the Vicks plant act on the same enzyme targeted by Type 2 diabetes drugs, helping your body maintain steadier blood sugar and improve insulin sensitivity naturally
- The plant’s essential oil contains more than 30 bioactive compounds that work together to support metabolic balance, immune defense, and cellular protection against oxidative stress
- Studies show that essential oil from Vicks plant effectively inhibits drug-resistant fungi responsible for stubborn skin, nail, and lung infections, offering a safe, natural alternative to synthetic antifungal medications
- Beyond personal health, Vicks plant supports ecological wellness by improving soil quality, repelling pests, and helping clean polluted environments through a process called phytoremediation
- Simple ways to use Vicks plant include diffusing its essential oil, applying diluted blends for skin support, and growing it at home for ongoing access to a natural remedy that promotes whole-body balance
Few plants bridge the worlds of folk wisdom and modern science as elegantly as Plectranthus neochilus — better known as Vicks plant, lobster flower, or in Brazil, boldo-rasteiro. This aromatic member of the mint family, instantly recognizable by its pungent, menthol-like scent and fleshy leaves, has long been part of traditional healing practices across Brazil and southern Africa.
Healers once relied on it to calm the stomach, ease headaches, and clear the liver — but scientists are now uncovering a much broader spectrum of benefits hidden in its essential oil. Research is revealing that this resilient herb is far more than a household digestive aid. Its complex blend of bioactive compounds interacts with key biological pathways that influence metabolic balance, immunity, and microbial defense.
Studies show that what was once used to soothe the gut could also support blood sugar regulation and protect against fungal infections. What makes this discovery remarkable is that a simple, time-honored garden plant — the same one many grow for its mosquito-repelling aroma — holds measurable therapeutic power.
The new evidence doesn’t replace its traditional uses; it expands them, showing how deeply nature’s chemistry aligns with human biology. This growing body of research has opened a new chapter for Plectranthus neochilus, one that invites a closer look at how its essential oils work within your body to restore strength and balance.
Essential Oils Act Like Natural Blood Sugar Balancers
A study in Current Pharmaceutical Analysis found that compounds from the essential oil of Vicks plant help regulate blood sugar in a way similar to prescription medications for Type 2 diabetes.1 Using advanced computer models, researchers showed that these natural molecules interact with an enzyme that breaks down hormones responsible for insulin release. When this enzyme is blocked, your body keeps more of these hormones active, allowing for steadier blood sugar control after meals.
• One compound stood out as especially powerful — Citronellyl butyrate, one of the main components in the plant’s oil, was the strongest at blocking the enzyme — performing almost as well as several diabetes drugs currently on the market. Other natural compounds, like citronellol and linalool, also showed strong effects and were found to be easily absorbed, well-tolerated, and safe for further development.
• The compounds act like a key fitting perfectly into a lock — Researchers described how these plant molecules attach tightly to the enzyme, forming stable bonds that block its activity. By doing so, they stop the breakdown of beneficial hormones that control both insulin release and appetite — two major factors in healthy metabolism.
• The plant’s oils are easily absorbed by your body — Because these compounds dissolve in fats, they pass through cell membranes quickly and reach the tissues involved in blood sugar regulation. This helps explain why essential oils produce effects relatively fast when used properly — either inhaled or taken in small, safe doses.
• Natural compounds could offer a safer way to support healthy metabolism — In the study’s simulations, citronellyl butyrate showed activity nearly identical to a class of diabetes drugs known as gliptins.
That means this simple herb could become a natural option for maintaining blood sugar without the common side effects linked to synthetic drugs. By helping your body use insulin more efficiently and keeping blood sugar stable, Vicks plant shows that ancient herbal remedies still have much to teach modern medicine.
Plant-Based Essential Oil Shows Strong Action Against Drug-Resistant Fungi
The same essential oil that shows promise for balancing blood sugar also demonstrates impressive power in another area of health — fighting fungal infections that resist conventional treatment. Research published in the International Journal of Complementary & Alternative Medicine tested the antifungal strength of essential oils from Vicks plant and Tagetes erecta (marigold).2
The study targeted fungi responsible for common but stubborn skin, nail, and lung infections that are increasingly resistant to conventional antifungal drugs. These infections are especially dangerous for people with weakened immune systems, such as those undergoing cancer treatment, living with HIV, or recovering from organ transplants.
• The essential oil of Plectranthus neochilus showed strong antifungal power, while marigold oil did not — The researchers measured the smallest amount of oil needed to stop fungal growth. Vicks plant oil stopped the fungi Rhizopus stolonifera at just 125 micrograms per milliliter, a level considered “promising” for antifungal activity.
In contrast, marigold oil showed no significant activity, even at much higher concentrations above 1,000 micrograms per milliliter. This makes Vicks plant a clear standout for natural antifungal applications.
• The plant’s antifungal strength comes from its unique blend of compounds — The essential oil contained more than 30 natural compounds known for their antimicrobial and cell-protective properties. Caryophyllene oxide, in particular, has been widely studied for use in antifungal creams, foods, and cosmetics because it damages fungal membranes and prevents their growth.
• The oil’s compounds appear to work together to boost their effectiveness — Instead of acting alone, these molecules interact synergistically — meaning they reinforce one another’s effects. This teamwork allows the oil to punch holes in the fungal cell wall, causing the cells to lose their structure and die. Unlike synthetic drugs that target only one pathway, this multi-targeted attack makes resistance far less likely, providing a major advantage for long-term use.
• Researchers believe this oil could replace or enhance current antifungal drugs — Modern antifungals are losing effectiveness and often cause serious side effects, including liver toxicity and nausea. By contrast, Vicks plant essential oil was described as both safe and effective at low concentrations. Its ability to fight fungus that causes skin and respiratory infections, as well as food spoilage, positions it as a sustainable, natural alternative for both medical and agricultural use.
• This study was the first to document antifungal activity in Vicks plant oil — The authors emphasized its potential as a dual-purpose tool — for protecting human health and preventing fungal damage in crops and stored foods. This familiar aromatic plant — often grown for its mosquito-repelling scent — could also be one of the most promising natural defenses against fungal infections in a world facing rising drug resistance.

Vicks Plant Shown to Support Both Human and Environmental Health
Researchers in Brazil reviewed decades of research to understand how the same plant that fights infection and balances metabolism also strengthens ecosystems and supports sustainable agriculture.3
Published in Ciência e Natura, this review examined prior studies on the plant’s chemical composition, pharmacological benefits, and ecological importance. The authors aimed to consolidate what is known about its active compounds, its medicinal uses in traditional practices, and its applications in agriculture and environmental restoration.
• The plant contains powerful antioxidant, antiparasitic, and antimicrobial compounds — Vicks plant is rich in natural chemicals that protect cells from oxidative stress. Oxidative stress refers to damage caused by free radicals, unstable molecules that harm tissues and accelerate aging.
These compounds neutralize free radicals and also inhibit the growth of harmful bacteria and fungi, explaining why the plant has been used traditionally to treat infections and promote liver and digestive health. The review noted its activity against a parasite responsible for schistosomiasis, a parasitic disease caused by blood flukes that live in freshwater snails and infect humans through the skin.
• Beyond medicine, the review revealed ecological and agricultural applications — Vicks plant proved valuable for pest management, natural soil improvement, and even urban landscaping. The plant also adapts easily to poor soil and drought conditions, suggesting it could be used for reforestation or pollution control through phytoremediation — a process where plants absorb and detoxify environmental pollutants.
• Vicks plant is a sustainable economic resource — Its combination of resilience, medicinal potency, and environmental benefits makes it suitable for small-scale farmers, herbal product manufacturers, and natural health practitioners. The researchers noted that industrial-scale extraction of its essential oil could support both health and ecological industries without harming the environment.
By validating folk remedies through chemical and pharmacological evidence, the review demonstrates that this plant offers more than symptom relief — it represents a holistic approach to health that integrates body, environment, and sustainability.
How to Use Vicks Plant for Whole-Body Balance
If you’ve been struggling with blood sugar swings, stubborn fungal issues, or sluggish energy, the first thing to focus on is balance — inside and out. The studies above show that Vicks plant works by targeting the same biological roots that cause metabolic stress and immune weakness. You can use this information in real life to strengthen your system naturally and safely. Here are five practical ways to start:
1. Support your metabolic balance through a healthy lifestyle — Essential oils from Vicks plant are just one supportive tool in a much larger strategy to support long-term metabolic health. To truly lower your diabetes risk, you need to focus on restoring mitochondrial function — your cells’ ability to make energy efficiently. That means eliminating processed foods, especially those made with vegetable oils high in linoleic acid (LA), which damage mitochondria and reduce cellular energy.
You also need to eat enough healthy carbohydrates — aim for about 250 grams per day from sources like root vegetables, fruit, and white rice — to fuel your mitochondria properly. Environmental factors like endocrine-disrupting chemicals in plastics and electromagnetic fields (EMFs) interfere with mitochondrial repair, so reducing your exposure to these hidden stressors is just as important as what you eat.
Essential oils help, but only when your broader lifestyle supports energy production at the cellular level.
2. Use essential oils strategically to support overall balance and resilience — Essential oils are concentrated plant extracts that work through both scent and skin absorption to influence your body’s stress response, immune activity, and energy metabolism. The key is consistency and moderation — just a few drops diffused in your home or blended with a carrier oil like coconut have measurable effects on mood, focus, and relaxation.
Essential oil compounds from Vicks plant, lavender, rosemary, and citrus each offer unique benefits, from promoting calm to supporting immune defense. When used intentionally, essential oils help create an environment that keeps your body’s natural systems — including blood sugar control, digestion, and immune health — functioning in harmony.
3. Target fungal issues at the source — not just the symptoms — Chronic yeast or fungal infections, whether on your skin, nails, or in your gut, often signal deeper imbalance. You can support healing by keeping your internal terrain less hospitable to fungal growth: limit ultraprocessed foods, include fermented foods like sauerkraut or kefir, and apply diluted essential oil blends topically to affected areas.
This approach helps your body correct the underlying imbalance rather than relying solely on synthetic antifungal creams that lose effectiveness over time.
4. Grow your own healing garden — You don’t need a tropical climate to cultivate Vicks plant — it thrives in poor soil and sunlight. Keeping the plant at home gives you easy access to its leaves for teas and tinctures while adding a natural air purifier to your environment. Growing it also builds the confidence that you can take control of your own health through simple, daily choices.
5. Adopt natural daily rhythms to restore your body’s balance — Stress throws your blood sugar, hormones, and immunity off track. Build simple rhythms into your day — wake with sunlight exposure, eat at consistent times, and unplug from screens at night. Pair this with five minutes of breathing, stretching, or gratitude journaling to calm your nervous system.
Just as Vicks plant compounds help restore internal balance at the cellular level, your routines restore harmony at the system level. When you focus on building strength at the root — your metabolism, gut, and immune system — the rest of your health follows naturally.
FAQs About Vicks Plant for Health
Q: What is Vicks plant, and why is it gaining attention in modern research?
A: Vicks plant (Plectranthus neochilus), also known as lobster flower or boldo-rasteiro in Brazil, is a fragrant herb from the mint family long used in traditional medicine for digestion, headaches, and liver support. Modern studies show that its essential oils contain compounds with measurable effects on blood sugar regulation, antifungal defense, and antioxidant protection, making it important for both medicinal and ecological uses.
Q: How does Vicks plant support healthy blood sugar levels?
A: Research published in Current Pharmaceutical Analysis found that compounds in the plant’s essential oil — especially citronellyl butyrate — work similarly to prescription diabetes drugs by blocking an enzyme that breaks down hormones involved in insulin release.4 This helps your body maintain steadier blood sugar after meals and improves insulin sensitivity naturally.
Q: What makes essential oil from Vicks plant effective against fungal infections?
A: A study in the International Journal of Complementary & Alternative Medicine showed that the oil was highly effective at stopping the growth of a fungus responsible for skin and lung infections.5 Its antifungal strength comes from a mix of natural compounds. Because these compounds work together through multiple mechanisms, the fungus is less likely to develop resistance compared with synthetic antifungal drugs.
Q: Does Vicks plant offer benefits beyond medicine?
A: Yes. A review published in Ciência e Natura found that Vicks plant contributes to environmental health as well as human wellness. It improves soil quality, repels pests naturally, tolerates drought, and helps clean polluted environments through phytoremediation — a process where plants absorb and detoxify contaminants. This makes it valuable not only for herbal medicine but also for sustainable agriculture and ecological restoration.
Q: How can I safely use Vicks plant and its essential oil at home?
A: You can grow Vicks plant easily in sunny areas or containers, then use its leaves to make teas, tinctures, or infused oils. The essential oil can be diffused for stress relief or diluted with a carrier oil for topical use to support skin and immune health. Like all concentrated plant extracts, essential oils should be used in moderation and not ingested directly unless under expert guidance.
Regular, consistent use as part of a balanced lifestyle — alongside a nutrient-rich diet and stress management — helps reinforce the plant’s benefits for metabolism, immunity, and overall resilience.
The Importance of Getting Regular Health Tests

https://articles.mercola.com/sites/articles/archive/2025/08/16/importance-of-getting-regular-health-tests.aspx
Analysis by Dr. Joseph Mercola August 16, 2025
Story at-a-glance
- Regular lab testing provides precise, actionable insights that enable early detection of possible diseases to improve long-term health outcomes
- Iron overload testing is crucial since excess iron is more common than deficiency; check serum ferritin levels and GGT enzyme levels for accuracy
- Hormone testing reveals metabolic health by measuring cortisol for stress levels, testosterone for mortality risk, and insulin resistance through HOMA-IR calculations
- Comprehensive biomarker monitoring includes vitamin D levels, complete thyroid panel beyond thyroid-stimulating hormone (TSH), and NAD+ testing for cellular function
- Biannual gut microbiome testing provides insights into bacterial balance, enabling smarter dietary decisions
When was the last time you had a thorough assessment of your health? Guessing about the current state of your health can lead to risky assumptions and dangerous oversights. Without concrete information, symptoms are likely to be misinterpreted or dismissed, allowing underlying issues to progress unnoticed. On the other hand, too much intake of a specific nutrient will also lead to health issues.
Lab testing removes uncertainty by providing precise, actionable insights into your health. By leveraging data-driven results, you gain clarity about your body’s true state, enabling you to select the optimal strategy to boost your health and proactively address concerns. The following are the tests I recommend that you take to keep you updated on what’s happening inside your body.
How to Test for Iron
One good reason why I recommend taking regular tests is to catch an unsuspecting health problem affecting many people — iron overload. In fact, it’s more widespread than iron deficiency. In addition, I’ve also written a paper about the duality of iron as a toxin and a nutrient, which will be published in the future. The recommendations I mention below stem from the findings of that specific research.
• How iron is normally tested — Checking for excess iron is straightforward and starts with a basic serum ferritin test, which shows how much iron your body has stored. This test reveals if your iron storage has reached higher-than-normal levels.
For context, transferrin refers to a protein produced in your liver that transports (hence the “transfer” in the name) iron molecules it binds to, transporting it to tissues. One example is your bone marrow, which requires iron to create new blood cells.1
• Transferrin saturation (TSAT) — While a serum ferritin test is a cornerstone test, it shows an incomplete picture. It works best alongside a TSAT test.
TSAT levels — calculated as serum iron divided by total iron-binding capacity (TIBC) then multiplied by 100 — shows the current amount of transferrin protein that’s bound to iron. Thus, it shows you the current iron levels you have available for erythropoiesis, commonly known as red blood cell production.
• Results to watch out for — When it comes to serum ferritin levels, I believe that the ideal range is between 30 and 100 ng/mL (nanograms per milliliter). This is sufficient for hemoglobin synthesis and avoids iron accumulation that can lead to oxidative stress in your body.
As for TSAT, my research indicates that the ideal range is between 25% and 35%. If regular tests show a range above 35%, you likely have iron overload. At 35% to 40%, iron that isn’t bound by transferrin protein — also known as toxic non-transferrin-bound iron (NTBI) — will damage your vital organs.2 In fact, TSAT ranges between 45% and 55% are linked to a 60% to 67% increase in all-cause mortality.
•Ideal ranges — To summarize, healthy results should show TSAT levels between 25% and 35%, alongside serum ferritin levels between 30 and 100 ng/mL.
Now, if your combined results show TSAT levels below 20% and serum ferritin levels below 15 micrograms per liter (µg/L), you likely have depleted iron reserves. Conversely, TSAT levels above 45% and ferritin levels above 100 ng/mL indicate excess iron. Taken altogether, serum ferritin not only serve as diagnostic markers — they also function as risk predictors.
• Other tests that detect iron — A comprehensive assessment usually includes an iron panel, complete blood count (CBC), gamma-glutamyl transferase (GGT), and a metabolic panel to fully understand your body’s iron status and overall health.
A healthy ferritin level is between 20 and 40 ng/mL. If results show that you’re below 20 ng/mL, you’re deficient in iron, which isn’t what you also want to happen. Conversely, you want your ferritin below 100 ng/mL, which is the maximum cut off.
• GGT test — This refers to the enzyme mainly produced by the liver, and is responsible for breaking down medications and toxins. When too much iron builds up in your body, it can harm your liver cells, causing GGT levels to rise significantly in your bloodstream.
What’s great about this test is that it also gives you insights on your excess free iron, as well as your risk for sudden death, insulin resistance, and cardiometabolic disease. Once you have your results, refer to the table below to know where you stand:
| Ideal GGT Level, units per liter (U/L) | Average level, above which your risk for chronic disease increases significantly | “Normal” GGT Level | |
|---|---|---|---|
| Men | Less than 16 U/L | 25 U/L | Up to 70 U/L |
| Women | Less than 9 U/L | 18 U/L | Up to 45 U/L |
Fine-Tuning Your Lifestyle for Longevity
Testing for possible nutrient deficiencies (or overload) is just one aspect of the big picture. You also need to test for other biomarkers, such as your hormones (testosterone, cortisol, and insulin) to detect your current stress levels. Doing so will lead to better metabolic health management.
• How cortisol is measured — Cortisol is produced by your adrenal glands, and it can be detected via your blood, urine, or saliva. Once samples are provided, be sure to follow your doctor’s instructions to generate the most accurate results possible.3
According to the Cleveland Clinic, cortisol in the blood, urine, or saliva are at their highest during the early morning and then decline afterward — midnight is the lowest point.4
• What your cortisol levels tell you about your health — In addition to measuring your stress levels, cortisol tests help rule out other conditions. For example, Addison’s disease occurs when your body isn’t producing enough cortisol. Conversely, Cushing’s syndrome is marked by high cortisol levels. Tumors are also marked by elevated cortisol.5
Finding out your current cortisol levels is important for overall health. It drastically accelerates aging and even contributes to muscle degradation over time. Lastly, it contributes to inflammation and a weakened immune system.
• The importance of testosterone — In a previous article, I cited research showing the link between sex hormones and mortality risk in men. Basically, if your testosterone levels drop by 213 ng/dL (nanograms per deciliter), you have a higher risk of all-cause mortality. In addition, testosterone levels below 153 ng/dL were associated with increased cardiovascular mortality risk.
• Ideal testosterone range — To find out your current levels, you’ll need to have your blood tested. That said, what’s a healthy range? In this article, I mentioned 300 to 1,000 ng/dL as a baseline.
• Testing for insulin resistance — In addition to cortisol, another crucial test that I recommend you take is measuring your insulin resistance. This is essential because results will serve as warning signs for your metabolic health. That said, insulin resistance is measured via the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) test. It calculates how your fasting glucose and insulin levels interact, and finds out how your body uses insulin.
• Interpreting HOMA-IR results — Below is a breakdown on how the HOMA-IR test is calculated. A score below 1 means you are currently insulin-sensitive and functioning well. Anything above that means that you currently have insulin resistance.
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 (millimoles per liter)
◦ Fasting insulin is measured in μIU/mL, and
◦ 22.5 is the normalizing factor for this unit of measurement

Testing for Other Important Biomarkers
So far, I’ve covered the importance of having your iron, cortisol, insulin resistance, and testosterone levels tested. While they may seem like a lot, there’s still a few more tests that need to be done.
• Monitor your vitamin D — This nutrient is a crucial contributor to optimal health, and I’ve espoused its importance for many years now. Considering this, a simple blood test is all you need to know your current levels.
My recommended range is between 60 ng/mL and 80 ng/mL, and the cutoff for sufficiency is around 40 ng/mL. Once you’ve confirmed your level, you’ll know how much sun exposure or supplementation (if needed) is necessary for you to reach the ideal range. Then, retest in the next three to four months to make sure you’ve hit your goals.
• Don’t forget your thyroid hormones — Your endocrine system is a complex network of glands and organs that regulate hormone production. Among the many hormones produced in your body, the ones produced in the thyroid are perhaps the most important because they help regulate metabolism and are found in nearly every physiological process within you.
• Understanding thyroid antibodies — Examples include thyroglobulin antibodies (TgAb) and thyroid peroxidase antibodies (TPOAb). Results will give you deeper insight into whether autoimmune processes are attacking your thyroid gland. Pairing these antibody results with symptoms helps you make meaningful connections and clarifies what’s really going on with your body, particularly if you’re dealing with an autoimmune condition.
• Traditional thyroid assessments aren’t effective anymore — Testing for thyroid-stimulating hormone (TSH) alone often misses underlying issues. That’s because TSH levels fluctuate significantly and you’ll even appear relatively normal even when you’re actually experiencing severe symptoms.
For instance, individuals with Hashimoto’s thyroiditis might have completely normal hormone levels yet feel persistently unwell. Similarly, basal body temperature is also an unreliable indicator of thyroid health, as it can be influenced by multiple factors unrelated to thyroid function.
• How to test thyroid function — A full thyroid assessment should show the following results:
◦Low TSH
◦T3 levels in the upper range
◦rT3 levels in the lower range
◦Moderate T4 levels
However, note that even “normal” results will not guarantee that your thyroid is functioning properly. For deeper insight, test for rT3 and cholesterol. Small amounts of rT3 are normal and act as a buffer against thyroid overactivity. On the other end, elevated rT3 is problematic because it competes with T3, reducing your metabolic rate. Elevated cholesterol levels also usually signal suboptimal thyroid function.
Importance of NAD+ Testing
Nicotinamide adenine dinucleotide (NAD+) is an important molecule in your body. It plays a role in converting food to energy, as well as maintaining DNA integrity and proper cell function.
• A new test will come out soon — I’m excited to announce the upcoming Mitochondrial Wellness Test Kit, which will provide a snapshot of your latest mitochondrial function. While helpful, certain specialized tests will be needed to understand the nuances of your health.
• Current NAD+ testing is unsatisfactory — NAD+ rapidly deteriorates once it’s outside your cells, making accurate measurement tricky. Because of this fragility, samples require immediate handling and specialized techniques to avoid losing accuracy.
Typically, precise NAD+ measurement demands blood samples to be drawn and analyzed swiftly within the same specialized research facility — something not possible at most regular clinics. Transporting samples between labs also compromises results significantly due to degradation. However, these challenges haven’t stopped our mission to deliver valuable health insights.
• NAD+ testing standards will rise — My team and I have developed an innovative approach that bypasses the complexity of direct NAD+ measurement. Instead, our method evaluates your NAD+ status indirectly by examining the redox balance among these essential markers — acetoacetate and betahydroxybutyrate, lactate and pyruvate, and the oxidized and reduced forms of glutathione.
• The test will be affordable — I’m proud to share that this cutting-edge NAD+ test is inexpensive, giving more people access to their current cellular health. More announcements will be made once this product is available.
Assessing Your Gut Health
Another crucial aspect of your health that needs to be tested regularly is your gut function. As you know, certain gut strains are beneficial, while others aren’t. Thus, figuring out which bacteria are dominating your gut will give you an insight to what’s happening.
• Gut Microbiome Wellness Test Kit — Just like the Mitochondrial Wellness Test Kit, my team and I will be releasing the Gut Microbiome Wellness Test Kit. It’s uniquely crafted to help you gain insights into your gut bacteria’s profile. It will seamlessly pair with the upcoming Mercola Health Coach app, providing you with a seamless end-to-end journey — from collecting your sample to interpreting your results.
To paint a picture of this process, you’ll need to send over a fecal sample. Afterward, you’ll be provided with a detailed breakdown of key bacterial species, allowing you to make smarter dietary and lifestyle decisions. To encourage broad access among the public, we’re also giving it an affordable price tag.
• Frequency of gut microbiome testing — One major reason why we’ve made this test affordable is to encourage repeat testing, ideally twice a year. This is needed to see whether your situation has improved or worsened, and you cannot know what your status is if a single test already requires a significant amount of cash.
Tips on Addressing Nutritional and Hormonal Deficiencies
The reason why I recommend you get yourself screened is to help save you time and money. For example, if one vitamin is already at an optimal range, you can focus your effort on others that need more attention. That said, I recommend going through the following articles. They contain helpful strategies to help you maintain optimal health after you’ve completed your tests:
- Everything You Need to Know About Vitamin D for Your Health
- High Iron Levels Threaten Bone Health and Increase Fracture Risk
- How Low Testosterone Affects Men’s Health
- Blocking Cortisol Extends Lifespan by Improving Mitochondrial Function
- Key Nutrients to Support Optimal Thyroid Health
- The Crucial Role of NAD+ in Optimal Health
- Unlocking the Secrets of Gut Health
Frequently Asked Questions (FAQs) About Regular Health Screenings
Q: Why is guessing about your health risky?
A: Guessing or relying on symptoms alone can result in serious health issues going undetected, delaying necessary treatments and reducing your chances of successful recovery. Accurate lab testing removes uncertainty, providing clear insights into your health status.
Q: What tests are essential for assessing iron overload?
A: Begin with a serum ferritin test, which reveals how much iron your body stores. For a comprehensive view, consider an iron panel, Complete Blood Count (CBC), gamma-glutamyl transferase (GGT), and a metabolic panel to fully evaluate your iron levels and overall health risks.
Q: Why is it important to monitor cortisol and testosterone levels?
A: Cortisol levels reflect stress and inflammation, significantly influencing aging, muscle health, and immune function. Testosterone is linked directly to mortality risk, cardiovascular health, and overall vitality. Regularly testing these hormones helps detect and manage imbalances early, protecting your long-term health.
Q: How can you accurately assess your thyroid health?
A: Traditional testing methods, like TSH levels or basal body temperature alone, often fail to identify underlying thyroid conditions such as Hashimoto’s thyroiditis. Testing thyroid antibodies (TgAb and TPOAb), along with a comprehensive panel (TSH, T3, T4, reverse T3, cholesterol), provides a clearer picture and helps target autoimmune-related thyroid issues.
Q: How do NAD+ and gut microbiome tests contribute to overall wellness?
A: Measuring NAD+ indirectly through redox balance markers provides critical insights into mitochondrial and cellular health, influencing energy and metabolic functions. Gut microbiome testing identifies beneficial and harmful bacterial strains, guiding informed dietary and lifestyle adjustments. Both tests are designed to be affordable, accessible, and offer actionable results for improving overall wellness.
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.
Bay Leaves Help Lower Blood Sugar and Improve Cholesterol Levels

Analysis by Dr. Joseph Mercola May 19, 2025
Story at-a-glance
- According to research, consuming as little as 1 gram of bay leaves daily can lower fasting glucose by up to 26% and reduces LDL cholesterol by 40%, offering natural support for metabolic health
- Insulin sensitivity improves with regular bay leaf intake, as studies show it protects pancreatic beta cells and enhances the body’s ability to regulate blood sugar
- Liver and kidney function benefit from bay leaf extract, which reduces inflammation, improves enzyme balance, and prevents diabetes-related organ damage
- Powerful antioxidants in bay leaves fight oxidative stress and inflammation, lowering the risk of metabolic dysfunction, heart disease, and complications linked to diabetes
- Try adding bay leaves to your meals, brewing them into tea, or using them in powdered form to provide an easy, natural way to regulate blood sugar and improve overall health
Bay leaves (Laurus nobilis L.) have been a staple in traditional medicine and cooking for centuries, but modern research now reveals something far more important about this common herb. Studies show that bay leaves significantly lower blood sugar levels and improve cholesterol, making them a powerful tool for managing your metabolic health.
Bay leaves also contain beneficial compounds that help protect cells from oxidative stress, which is one of the key drivers of inflammation and chronic disease. This ability to support both glucose metabolism and lipid balance makes them an overlooked but valuable addition to a health-conscious diet.
Bay Leaves Protect Your Organs While Lowering Blood Sugar
A 2021 animal study published in the Annals of Medicine and Surgery journal1 examined how bay leaf helps mitigate the damage caused by diabetes, particularly in the pancreas, liver and kidneys — organs that are often severely affected by the disease. Over four weeks, diabetic rats were given bay leaf extract, and their blood sugar levels, insulin response and organ function were closely monitored.
- Bay leaf extract led to a significant drop in blood sugar — The rats that received the bay leaf extract experienced a significant drop in blood sugar, bringing their glucose levels much closer to normal compared to diabetic rats that received no treatment.
- Pancreatic beta cells were better preserved — These cells are responsible for producing insulin. In untreated diabetic rats, these insulin-producing cells were severely damaged, leading to insulin dysfunction and uncontrolled blood sugar. In contrast, rats that received bay leaf extract showed stronger insulin production and healthier pancreatic tissue.
- Untreated diabetic rats had severe liver damage — The liver, which helps regulate glucose and lipid metabolism, often becomes inflamed and overloaded with fat in diabetics. The researchers found that rats that didn’t receive bay leaf extract had liver necrosis (cell death), fatty deposits and structural degeneration.
- Bay leaf extract-treated rats had improved liver function — Their liver enzyme (AST, ALT, and GGT) levels, key markers of liver function, improved significantly, suggesting reduced liver stress and better overall metabolic control. Liver enzymes are critical for detoxification and metabolic health, and when elevated, it means the liver is under strain. Bay leaf-treated rats had levels that were closer to those of healthy rats.
- Remarkable improvements were also seen in kidney function — Diabetes causes kidney damage due to high blood sugar and inflammation, often resulting in diabetic nephropathy. In this study, untreated diabetic rats had kidney damage, inflammation, and abnormal structural changes. Bay leaf extract prevented much of the damage, helping reduce cellular stress and maintain normal kidney architecture in the treated rats.2
What Makes Bay Leaves So Powerful?
Bay leaves have a positive effect on insulin signaling, which is one of the key mechanisms behind its antidiabetic effects. Insulin is the hormone responsible for moving sugar from the bloodstream into cells, but when you have diabetes, your cells become resistant to insulin’s effects.
- Bay leaves improve insulin signaling — In the animal study above, bay leaf extract was found to enhance insulin sensitivity. This leads to lower blood sugar levels and improves glucose metabolism, key factors in preventing long-term complications of diabetes.
- Potent antioxidants in bay leaves — 1,8-cineole, α-terpinyl acetate and linalool in bay leaves help reduce oxidative stress, which is a major driver of diabetic complications. High blood sugar generates free radicals, unstable molecules that damage cells and accelerate disease progression. Bay leaf’s potent antioxidants help neutralize free radicals.
- Bioactive compounds in bay leaves help regulate lipid metabolism — In diabetes, cholesterol and triglyceride levels often become dangerously unbalanced, increasing the risk of heart disease. The study showed that rats treated with bay leaf extract had better lipid profiles (reduced LDL cholesterol and triglycerides and increased HDL cholesterol), which helped support heart health and overall metabolic stability.
This research provides compelling evidence that bay leaves are more than just a spice — they’re a powerful tool for metabolic health. “We believe that further preclinical research into the utility of L. nobilis treatment may indicate its suitability as a potential treatment in diabetic patients,” the study authors wrote.3

Human Research Confirms Results
Previous research has demonstrated these effects in humans as well. A study published in the Journal of Clinical Biochemistry and Nutrition4 examined the effects of bay leaf consumption on blood sugar and cholesterol levels in Type 2 diabetics. Their primary goal was to determine whether bay leaves could naturally help control glucose levels and improve lipid profiles in people who are at risk of diabetes and heart disease.
- Different bay leaf doses were tested over a 30-day period — The study involved 40 participants, all diagnosed with Type 2 diabetes. They were divided into four groups, each receiving a different amount of bay leaves (1, 2 or 3 grams of ground bay leaves in capsule form) or a placebo. After just 10 days, significant changes were already evident in the groups taking bay leaves, and more significant improvements were seen after 30 days.
- Bay leaves help regulate glucose more effectively over time — Participants consuming bay leaves saw fasting blood sugar levels drop by 21% to 26%, with the most significant reductions occurring in those taking 1 or 3 grams daily. Even more interesting, these lower blood sugar levels persisted for 10 days after stopping bay leaf consumption, indicating a lasting effect.
- Cholesterol levels also saw major improvements — Across all bay leaf groups, total cholesterol levels dropped between 20% and 24%, with the biggest reductions seen in LDL cholesterol (“bad” cholesterol). LDL levels plummeted by as much as 40%, a decrease that rivals the effects of some cholesterol-lowering medications.
- Triglycerides decreased significantly — In the 1-gram group, triglycerides dropped by 34%, while the 2-gram group saw a 25% reduction. Even after stopping bay leaf consumption, their levels remained lower than before the study, reinforcing the long-term benefits.
- HDL cholesterol levels soared — The researchers found that HDL “good” cholesterol rose by 19% to 29%, improving participants’ overall heart health. This shift in cholesterol ratios is crucial, as high LDL and low HDL levels are key drivers of heart disease, stroke and other cardiovascular problems.
The researchers noted that none of the participants were taking insulin, and they all continued their usual diabetes medications and diets during the study. This setup allowed them to identify how bay leaves affected the diabetics’ health beyond the effects of their existing treatments.
Another interesting aspect is that the most notable benefits were observed in the 1-gram group. They had the most consistent improvements across blood sugar, cholesterol, and triglycerides. This suggests that even a small daily amount of bay leaves provides meaningful health benefits, making it easy to incorporate into a regular diet.5
What Else Is Bay Leaf Good For?
Bay leaves are an excellent source of vitamins A and C, iron, manganese, copper and calcium — all of these are antioxidants with free radical-scavenging abilities, and positively impact your eyesight, bones, blood and more.6 Below are other health benefits associated with bay leaves.
- Pain relief — In traditional medicine, bay leaves are used for alleviating digestive issues, like ulcer pain, heartburn, gas and colic. It’s also helpful in easing arthritis and headaches.7
- Protects against pathogenic bacteria — A study published in the Journal of Pathogen Research tested the antimicrobial and antioxidant properties of bay leaves against multiple bacterial strains, including Staphylococcus aureus, Escherichia coli (E.coli) and Pseudomonas aeruginosa. The results revealed strong antibacterial effects, particularly against S. aureus and E. coli.8
- Bioactive compounds provide immune support — Researchers attribute these effects to the flavonoids (kaempferol, myricetin and quercetin), polyphenols, and essential oils found in bay leaves, which all have well-documented anti-inflammatory and immune-supporting properties.
- Inhibits bacterial growth — The monoterpenes and sesquiterpenes in bay leaves also disrupt bacterial membranes and inhibit their ability to grow and multiply.9

How to Add Bay Leaves to Your Diet
If you’re looking for a natural way to improve your blood sugar levels and cholesterol, adding bay leaves to your diet is one of the easiest steps you can take. The best part? You don’t need much. As the studies above demonstrate, even a small amount daily makes a big difference. Here are tips to get the most out of bay leaves and improve your overall health:
1. Use whole bay leaves in cooking — The simplest way to start using bay leaves is to cook with them regularly. Add a couple of whole bay leaves to soups, stews, rice or slow-cooked meats. The leaves will infuse your food with their beneficial compounds while enhancing flavor. Just remember to remove them before serving, as they are not meant to be eaten whole.
2. Brew bay leaf tea — If you prefer a more direct way to consume bay leaves, make a tea by simmering two or three dried bay leaves in hot water for 10 minutes. This allows the active compounds to extract fully. Drink this tea daily to help regulate blood sugar and reduce oxidative stress. You can also add a squeeze of lemon or a teaspoon of raw honey if you want to enhance the taste.
There are other types of tea that are beneficial for diabetics. Learn more about them in my article, “Study Shows Tea Can Reduce Risk and Progression of Diabetes.”
3. Use ground bay leaves for maximum benefits — If you want a more concentrated effect, use ground bay leaves instead of whole ones. Sprinkle a small amount into sauces, curries or even mix it into a smoothie. This method ensures you consume the beneficial compounds directly without having to remove the leaves later.
4. Combine bay leaves with other antioxidant-rich foods — Bay leaves work even better when paired with other antioxidant-rich foods. Since oxidative stress contributes to insulin resistance and cholesterol imbalances, eating more fresh fruits, vegetables, and healthy fats alongside bay leaves further reduces inflammation and protects your cells.
Adding other herbs and spices to your meals gives you even more metabolic support. One example is cinnamon — read more about it in this article, “Cinnamon — An Ancient Spice That May Be Beneficial for Prediabetics.”
5. Be consistent and give it time — The studies on bay leaves showed significant improvements within 30 days, but these benefits are best sustained through long-term use. Make bay leaves a regular part of your meals and be patient as your body gradually improves insulin sensitivity, lowers LDL cholesterol and balances blood sugar levels. Like any natural approach, consistency is key.
Bay leaves offer a simple, natural way to support metabolic health, and incorporating them into your diet requires minimal effort. Whether you add them to your meals, brew them into tea, or use them as a seasoning, they are a powerful tool for improving glucose regulation and protecting your heart.
If you’re struggling with diabetes, there are other herbs and spices that will help manage your blood sugar levels. Read “These Herbs and Spices Can Help Deter Diabetes” for more information.

Probiotics Offer New Hope for Alzheimer’s and Other Neurodegenerative Diseases
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2025/03/20/probiotics-alzheimers-neurodegenerative-diseases.aspx
Analysis by Dr. Joseph Mercola March 20, 2025
STORY AT-A-GLANCE
- Probiotics may influence brain function through the gut-brain axis, offering benefits for neurodegenerative diseases like Alzheimer’s and Parkinson’s by improving gut health and reducing inflammation
- Studies suggest a link between gut health and cognitive function, indicating that an improved gut microbiome enhances mental health and may reduce inflammation associated with neurodegeneration
- Research indicates that probiotics could play a role in managing Alzheimer’s and Parkinson’s, offering a noninvasive treatment option that helps slow or reverse cognitive decline
- Biologically, the action of probiotics involves several interconnected pathways. By restoring a healthy balance of gut bacteria, probiotics reduce the production of harmful substances like lipopolysaccharides (LPS) that trigger inflammation in the brain
- Further studies are needed to confirm the long-term benefits of probiotics in neurodegenerative disease management, emphasizing the importance of continued research in this area
Neurodegenerative diseases (NDs) are disorders characterized by the progressive loss of structure or function of neurons, leading to their eventual death. This decline disrupts essential brain functions, resulting in symptoms that significantly impair daily living and overall quality of life.
Common neurodegenerative diseases include Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (ALS).1 Individuals affected by these conditions often experience memory loss, impaired movement, and difficulties with speech and coordination. As the diseases advance, patients may face severe cognitive and physical challenges, necessitating extensive care and support.
Neurodegenerative diseases now affect millions worldwide, with Alzheimer’s alone responsible for approximately 60% to 70% of dementia cases.2 On the other hand, the prevalence of Parkinson’s disease is expected to double by 2040, underscoring a growing public health concern.3 Additionally, ALS affects about 2 per 100,000 people in Europe and the U.S., with no known cure currently available.4
Risk Factors Associated with Neurodegenerative Diseases
Understanding the underlying causes of NDs is complex, as they often involve a combination of factors. For example, genetic mutations can predispose individuals to conditions like Alzheimer’s and Parkinson’s. According to a review published in the NPJ Parkinson’s Disease journal, genetic factors are linked to 56% to 79% of the risk for developing Alzheimer’s disease.5
• Environmental toxins — Exposure to heavy metals and pesticides, may contribute to neuronal damage. According to the aforementioned study:
“Several studies have suggested that lead (Pb), arsenic (As), and methyl mercury (MeHg) are also neurotoxins and can disrupt brain function, cause cognitive dysfunction, and increase the risk of AD and PD by disrupting mRNA splicing, the ubiquitin-proteasome system, the electron transport chain, and oxidative stress.”6
• Lifestyle factors — Poor diet, lack of exercise and chronic stress exacerbate NDs by affecting overall brain health and function. The progression from these underlying causes to full-blown NDs involves a cascade of biological events. Neurons, the brain’s communication cells, begin to lose their structure and function due to factors like oxidative stress and inflammation.
This deterioration disrupts the brain’s ability to process information, leading to symptoms such as memory loss and impaired motor skills. Over time, the cumulative effect of these disruptions results in the characteristic decline associated with NDs.
• Diagnosing NDs can be challenging — Often, symptoms overlap with other conditions, making it difficult to pinpoint the exact disease. For instance, memory loss could be attributed to normal aging, stress, or other medical issues, leading to potential misdiagnosis. Additionally, the lack of definitive biomarkers for many NDs means that diagnosis often relies on clinical assessments and patient history, which can be subjective and vary between practitioners.
• Limitations in diagnostic tools complicate the process — Imaging techniques like MRI and CT scans show brain changes, but these are not always specific to NDs. Blood tests and genetic screenings may offer clues but are not conclusive.
As a result, patients may undergo a lengthy diagnostic journey, experiencing uncertainty and anxiety while seeking answers. This underscores the need for more precise and reliable diagnostic methods to improve early detection and treatment outcomes.
Beyond the immediate symptoms, neurodegenerative diseases lead to profound emotional and financial burden for patients and their families. The progressive nature of these disorders often results in loss of independence, increased healthcare costs and emotional stress. Addressing these multifaceted challenges is crucial in improving patient outcomes and enhancing the quality of life for those affected.
Breakthrough Research Shows Probiotics’ Role in Alzheimer’s Disease Management
A recent study published in the journal Nutrients7 investigated the impact of probiotics on individuals diagnosed with Alzheimer’s disease. The research, conducted by Taiwanese researchers, aimed to determine whether introducing specific beneficial bacteria could influence cognitive function and reduce disease markers.
• Investigating the effects of probiotics — The study involved 60 elderly participants who were diagnosed with Alzheimer’s disease. They were assigned to either a probiotic treatment group or a placebo group over a 12-week period.
The probiotic group consumed a milk product containing strains such as Lactobacillus acidophilus, Lactobacillus casei, Bifidobacterium bifidum, and Lactobacillus fermentum. The primary goal was to assess any changes in cognitive function and Alzheimer’s disease markers as a result of the probiotic intervention.
• Probiotics improve cognitive function — Significant improvements were seen in the group that received probiotics compared to the placebo group. The probiotic group showed a notable increase in their Mini-Mental State Examination (MMSE) scores, indicating enhanced cognitive function. In contrast, those who took the placebo experienced a decline in their MMSE scores over the same period.
• Probiotics’ positive effects against inflammation — The probiotic group demonstrated a reduction in inflammation markers, which are often elevated in Alzheimer’s patients. “Considering these findings, specific probiotics demonstrate robust and effective antioxidant capabilities,” the study authors report.8

Probiotics Reduce Inflammation and Oxidative Stress
The mechanism behind these improvements is believed to involve the gut-brain axis, a communication network between the gastrointestinal tract and the brain.
• Probiotics balance your gut health — Probiotics help maintain a healthy balance of gut microbiota, which in turn influence brain function. By promoting a diverse and balanced microbiome, probiotics may reduce systemic inflammation and oxidative stress, both of which are implicated in the progression of Alzheimer’s disease. For more information on how gut health affects your mental health, read “Gut Health’s Impact on Mental Well-Being.”
• Benefits of SCFAs — Short-chain fatty acids (SCFAs) are metabolites produced by beneficial bacteria in the gut. SCFAs have been shown to support brain health by providing energy to neurons and reducing inflammation. The increased abundance of Lactobacillus species in the probiotic group likely contributed to higher SCFA levels, fostering an environment conducive to cognitive stability and improvement.
• Benefits are observed in a short amount of time — Cognitive improvements were observed after just 12 weeks of probiotic supplementation, suggesting that the benefits of probiotics can manifest relatively quickly. This rapid response underscores the potential of probiotics as a viable intervention for slowing or even reversing aspects of cognitive decline in Alzheimer’s patients.
Comparing the effects of probiotics to other variables in the study, probiotics consistently outperformed the placebo in all measured outcomes. While both groups participated in the same environment and received similar care apart from the probiotic intervention, only the probiotic group showed meaningful improvements in physiological markers related to brain health. This stark contrast emphasizes the specific role that probiotics play in enhancing brain health.
Probiotics’ Mechanisms of Action Against Neurodegenerative Disorders
Biologically, the action of probiotics involves several interconnected pathways. By restoring a healthy balance of gut bacteria, probiotics reduce the production of harmful substances like lipopolysaccharides (LPS) that trigger inflammation in the brain.9
• Enhancing the integrity of the gut barrier — They prevent the leakage of proinflammatory agents into the bloodstream, which could otherwise reach the brain and exacerbate neuroinflammation.10
• Affecting neurotransmitter production — Probiotics influence the production of neurotransmitters such as dopamine and gamma-aminobutyric acid (GABA).11 These chemicals are crucial for mood regulation and cognitive function. By increasing the levels of these neurotransmitters, probiotics contribute to improved mental health and cognitive resilience against the degenerative processes of Alzheimer’s disease.
Four Ways to Support Your Brain Through Gut Health
Your gut microbiome acts as a second brain, directly influencing your cognitive function and neurological health, and how you nourish it plays a significant role in your risk for neurodegenerative conditions. For example, a study published in Scientific Reports showed that certain bacterial strains in the gut, such as Collinsella, Lachnospira, and Veillonella, increased the risk of Alzheimer’s disease.12
However, they also identified strains that provide protective benefits against Alzheimer’s disease, such as Eubacterium nodatum and Eisenbergiella. These produce short-chain fatty acids (SCFAs), particularly butyrate, from dietary carbohydrates.
Butyrate nourishes your colonic epithelial cells, reinforcing the intestinal barrier. SCFAs also stimulate mucin production, creating a protective shield against harmful bacteria. Akkermansia muciniphila also produces SCFAs, and research has shown that Alzheimer’s patients tend to have very low levels of this important keystone species.13 Here are four proven strategies geared toward optimizing the Akkermansia in your gut to enhance your brain health:
1. Increase Akkermansia through targeted diet and supplementation — Prioritize foods and supplements that promote the growth of Akkermansia. Include well-cooked, prebiotic-rich vegetables and fiber sources that nourish this crucial bacterium.
Consider high-quality supplements specifically designed to enhance Akkermansia levels, supporting gut barrier integrity and reducing brain inflammation. Avoid processed foods and high-fat diets that can hinder Akkermansia growth.
2. Enhance beneficial short-chain fatty acids — Focus on increasing butyrate-producing bacteria alongside Akkermansia to protect against amyloid buildup in the brain. Incorporate fermented foods and resistant starches that feed these beneficial microbes.
Tailor your carbohydrate intake to support your unique microbiome, aiming for at least 250 grams of targeted carbs daily, and adjust based on your activity level to optimize Akkermansia and short-chain fatty acid production.
3. Support your gut-brain connection — Optimize your gut barrier integrity to prevent inflammatory compounds from reaching your brain. This includes removing inflammatory processed foods and supporting the growth of protective bacteria like Akkermansia, which strengthens your intestinal lining.
Maintain a balanced diet with sufficient carbohydrates tailored to your microbiome, and use pharmaceutical-grade supplements as needed to sustain Akkermansia levels.
4. Address systemic inflammation by promoting Akkermansia diversity — Lower inflammation throughout your body by enhancing microbiome diversity, with a specific emphasis on increasing Akkermansia.
Eliminate vegetable oils and other proinflammatory fats that damage gut bacteria, and incorporate foods that reduce inflammatory markers while supporting Akkermansia growth. Regularly monitor biomarkers such as C-reactive protein levels to track your progress in reducing systemic inflammation and maintaining a healthy gut microbiome.
Additional Strategies to Prevent Alzheimer’s Disease
Aside from optimizing your gut health and Akkermansia levels, there’s a plethora of helpful Alzheimer’s prevention strategies, several of which are outlined below:
• Avoid gluten and casein (primarily wheat and pasteurized dairy, but not dairy fat, such as butter) — As noted in a 2022 study,14 your blood-brain barrier is negatively affected by gluten. When bacteria enter your bloodstream, the risk of Alzheimer’s disease increases. Other cognitive disorders are linked to a weakened blood-brain barrier as well, such as Parkinson’s disease, anxiety and depression.
• Make sure you’re getting enough animal-based omega-3 fats — Omega-3 fats, namely EPA and DHA, help by preventing cell damage caused by Alzheimer’s disease, thereby slowing down its progression and lowering your risk of developing the disorder. That said, omega-3s are PUFAs, so don’t overdo it.
• Optimize your vitamin D level with safe sun exposure — Strong links between low levels of vitamin D in Alzheimer’s patients and poor outcomes on cognitive tests have been revealed. In a 2023 study,15 increasing vitamin D reduced dementia risk by 40%.
The best way to get vitamin D is through sensible sun exposure, aiming for a blood level between 60 and 80 ng/mL. However, you need to purge vegetable oils from your body before going into the sun at solar noon. The LA in your skin oxidizes when exposed to sunlight, causing inflammation and skin damage.
To protect your skin, avoid sun exposure during solar noon for four to six months as you work on removing LA from your body. Stick to sunlight during early morning and late afternoon in the meantime. For additional skin defense, you can take astaxanthin, a low-dose aspirin or molecular hydrogen. Niacinamide cream will also lower your risk of skin damage.
• Keep your fasting insulin levels below 3 — Insulin resistance is linked to accelerated brain aging, as well as neurodegeneration.16
• Eat a nutritious diet, rich in folate — Vegetables, without question, are your best form of folate. Avoid supplements like folic acid, which is the inferior synthetic version of folate. Research shows that folate is a protective factor against Alzheimer’s disease.17
• Avoid and eliminate mercury and aluminum from your body — Dental amalgam fillings, which are 50% mercury by weight, are one of the major sources of heavy metal toxicity. Make sure you use a biological dentist to have your amalgams removed. Sources of aluminum include antiperspirants, nonstick cookware and vaccine adjuvants.
• Make sure your iron isn’t elevated and donate blood if it is — A study18 published in Aging Medicine shows that excess iron increases your risk of Alzheimer’s disease by initiating the Fenton reaction, leading to increased oxidative stress.
• Exercise regularly — Exercise triggers beneficial changes that support cognitive function. Particularly, it’s been shown to improve blood flow to the brain, leading to an increase in biomarkers related to improved neuronal plasticity and better cell survival.19
• Eat blueberries and other antioxidant-rich foods — Wild blueberries, which have high anthocyanin and antioxidant content, are known to guard against neurological diseases.
• Challenge your mind daily — Mental stimulation, such as learning to play a musical instrument, is associated with a decreased risk of Alzheimer’s.20
• Avoid anticholinergics and statin drugs — Drugs that block acetylcholine, a nervous system neurotransmitter, have been shown to increase your risk of dementia. These drugs include certain nighttime pain relievers, antihistamines, sleep aids, certain antidepressants, medications to control incontinence, and certain narcotic pain relievers.
Statin drugs are particularly problematic because they suppress the synthesis of cholesterol, deplete your brain of CoQ10 and neurotransmitter precursors, and prevent adequate delivery of essential fatty acids and fat-soluble antioxidants to your brain by inhibiting the production of the indispensable carrier biomolecule known as low-density lipoprotein.
Frequently Asked Questions (FAQs) About Probiotics and Neurodegenerative Diseases
Q: How do probiotics impact neurodegenerative diseases like Alzheimer’s?

Analysis by Dr. Joseph Mercola February 22, 2025
STORY AT-A-GLANCE
- GLP-1 receptor agonists like Ozempic and Wegovy, originally intended as diabetes medications, have gained popularity for weight loss, leading to global shortages despite having modest benefits
- Research shows these drugs reduce seizures and substance addiction risks, but they increase the likelihood of 19 other health conditions, including fainting, kidney problems and pancreatic issues
- Common side effects include nausea, diarrhea, vomiting and abdominal pain, with potential risks of acute pancreatitis and thyroid cancer, making the trade-off dangerous for users
- Ozempic’s manufacturer Novo Nordisk reported $40.6 billion in revenue, highlighting how the “magic pill” mentality and ultraprocessed food consumption create a profitable cycle for pharmaceutical companies and food manufacturers
- Instead of relying on weight loss drugs, focus on optimizing cellular energy production through dietary changes, avoiding vegetable oils and supporting your gut and mitochondrial health
By now, most people around the world have heard of Ozempic and Wegovy, which are GLP-1 receptor agonists. These drugs, originally made for treating Type 2 diabetes, cause rapid weight loss, thus attracting individuals who have been struggling to lose weight for a long time. In fact, the effectiveness of these drugs has led to a global shortage.1 However, as with many other drugs that promise immediate results, there’s a catch.
Ozempic Hailed as a ‘Miracle Drug,’ but the Downsides Are Sinister
A report from The Epoch Times2 covered a study published in Nature Medicine,3 showing the impact of certain GLP-1 receptor agonists, sold under brand names such as Ozempic and Wegovy. As noted by The Epoch Times, “The media, patients, and even some doctors have dubbed the medications ‘miracle drugs’ because of their profound weight-loss effects.”4
In addition to weight loss, the study also noted that these drugs also lower the risk of “seizures and addiction to substances such as alcohol, cannabis, stimulants and opioids.”5 It’s believed that these drugs affect the brain’s neurological pathways related to reward and impulse control, explaining how these changes in behavior occur.6
Despite these benefits, the researchers caution potential, as there’s a dark side to these drugs that mainstream media and Big Pharma do not want you to see. According to the report, Ozempic increases your risk of developing a slew of other serious health conditions:7
“Researchers warn that these benefits come with an increased risk of 19 health conditions, such as syncope (fainting), arthritic disorders, and kidney and pancreatic problems.”
Similarly, a 2022 study found that commonly reported problems include nausea, diarrhea, vomiting and abdominal pain. An increased risk for acute pancreatitis and thyroid cancer was also noted.8 Meanwhile, Nature Medicine claims the benefits are “modest” at best:9
“While GLP-1RA drugs display effectiveness against a wide array of health problems, the magnitude of associated benefits is modest — about a 10% to 20% reduction for most outcomes.”
A Closer Look at the Research
The Nature Medicine study analyzed 215,970 diabetics using GLP-1 receptor agonists and compared them to multiple control groups: 159,465 taking sulfonylureas, 117,989 using DPP-4 inhibitors, and 258,614 on SGLT2 inhibitors. An additional control group of 536,068 used all three medications, while a separate baseline group of 1,203,097 received only standard care.10
They then produced a master list of health outcomes related to GLP-1 agonist receptor usage. As noted by The Epoch Times, while these drugs produced benefits, there were also significant adverse health outcomes:11
“Compared to usual care, GLP-1RA use was associated with a reduced risk of substance use and psychotic disorders, seizures, neurocognitive disorders (including Alzheimer’s disease and dementia), coagulation disorders, cardiometabolic disorders, infectious illnesses and several respiratory conditions.
There was an increased risk of gastrointestinal disorders, hypotension, syncope, arthritic disorders, nephrolithiasis, interstitial nephritis and drug-induced pancreatitis associated with GLP-1RA use compared to usual care. The results provide insights into the benefits and risks of GLP-1RAs and may be useful for informing clinical care and guiding research agendas.”
In a report by GoodRx, Stacia Woodcock, PharmD., outlines the mechanisms that lead to weight loss and other supposed benefits related to taking these drugs:12
• They signal your pancreas to release more insulin — After a meal, your blood glucose levels go up. Usually, the pancreas releases insulin when this happens to lower blood glucose levels. But in Type 2 diabetics, the body doesn’t always release enough. Incretin mimetics work on the pancreas to help raise insulin levels after you eat, which then lowers your blood glucose level.
• They increase your body’s sensitivity to insulin — Your body may also not respond as well to insulin if you’re diabetic. Incretin mimetics help increase insulin sensitivity, so your body can respond better to insulin when it’s released.
• They tell your liver to stop making glucose — This helps stop the production of new glucose to keep blood levels down.

The Cycle of Ultraprocessed Food and Ozempic Wrecks Public Health
As the weight-loss effects of GLP-1 receptor agonists gained widespread attention, Big Pharma’s profits in this market skyrocketed. According to The New York Times, Novo Nordisk, the maker of Ozempic and Wegovy, reported $40.6 billion in revenue in 2024; this figure is expected to jump by 16% to 24% in 2025.13
In the Tucker Carlson Show interview featured above, Dr. Casey Means, a Stanford-educated surgeon now focusing on functional medicine, expounds on the idea that a “magic pill” that causes weight loss and other supposed benefits appeals to millions of users:14
“I think it’s very dark. It’s a stranglehold on the U.S. population. Almost like solidifying this idea that there is a magic pill — I mean, literally, the book by Johann Ari is called ‘Magic Pill’ — and convincing us that, you know, salvation from our chronic health issues is going to be found in a shot when we are living in a toxic stew that’s destroying our cellular biology.”
Elsewhere in the interview, Means shares how ultraprocessed food contributes to obesity, thus cycling back to taking drugs that cause weight loss. In the end, only Big Pharma and Big Food are the real winners here, as millions of adults struggle with the damage they cause:15
“We are the only species in the world that has an obesity and chronic disease epidemic, the only species in the world that has a chronic disease and obesity epidemic because of ultraprocessed food.
You think about every other animal in the wild — they’re eating real, natural foods except for domesticated animals, which are also getting chronic diseases just like humans because they’re eating our food. But every other animal, they’re able to regulate their satiety. They’re not eating themselves to death like we are. We’re literally eating ourselves to death …
This could be on track to be the most profitable medication ever in human history. It will be if the powers that be let it. And what the unfortunate part is that it doesn’t take our bodies out of the toxic stew that’s crushing our biology. Yes, we may melt some fat and muscle without changing any of the other levers that we just talked about that are crushing our biology. So, this is not the public health solution.”
Practical Ways to Address Underlying Metabolic Challenges
I believe the key to maintaining a healthy weight is optimizing your cellular energy production. This requires a multifaceted approach that takes effort to implement, but it leads to safer, healthier results — something GLP-1 receptor agonists don’t offer. With that in mind, here are my recommendations:
1. Avoid Ozempic and other GLP-1 agonist receptor drugs — The most obvious strategy is avoiding GLP-1 agonist receptors in the first place. If you’re tempted to start, you owe it to yourself to read the study to understand the dangers.
Pills and injections offer short-term relief, but they often mask deeper imbalances in how your cells produce and use energy. Real improvement happens when you remove the factors that strain your metabolism rather than rely on a drug to force quick weight loss.
2. Remove vegetable oils from your diet — If you regularly consume ultraprocessed foods, I recommend stopping right now and replacing them with real, whole foods. Processed foods contain linoleic acid-rich vegetable oils that disrupt your metabolic pathways and alter how your body stores fat. Instead, cook your meals using tallow, grass fed butter or coconut oil.
To protect your health from further damage, limit your intake of linoleic acid to less than 5 grams per day from all sources. I recommend using Cronometer, an online food tracker, so you don’t go over this recommended range.
3. Shift your carbohydrate sources gradually — Avoid making sudden dietary changes that can shock your system. If your gut is compromised, start by introducing easily digestible carbohydrates like whole fruit or white rice before incorporating more complex carbs.
For severe gut issues, sip dextrose water throughout the day as a temporary aid to support healing, but limit its use to about two weeks. The goal is to provide your cells with a steady source of easy-to-digest, healthy carbohydrates for energy.
4. Consider your protein and collagen intake — I suggest aiming for 0.8 grams of protein per pound of lean body mass and balancing that amount so that about one-third comes from collagen. Doing this supports muscle maintenance, tissue repair and hormone balance.
If you exercise frequently, you would probably do well with a higher intake, but take it slow and listen to how your body responds. Stable protein intake is foundational for regulating cravings and stabilizing energy.
5. Support your gut and mitochondrial health with other healthy habits — I recommend getting daily sunlight exposure while being mindful of timing. If your diet previously included vegetable oils, avoid intense midday sun for at least six months to reduce the risk of sunburn and skin damage. Additionally, grounding in low-EMF environments can be beneficial if available — oceans, particularly in North America, tend to be the safest option.
In addition, moderate-intensity movement, such as walking, supports cellular energy production and aids in weight management. Gradual, consistent effort in these areas strengthens your metabolism and leads to lasting health improvements. I believe this approach is far superior to relying on a so-called “magic” drug like Ozempic.
Boost Your GLP-1 Naturally with Akkermansia
The idea of a quick-fix pill may be tempting, but it comes at a long-term cost to your health. A better approach is to naturally boost your GLP-1 levels by supporting Akkermansia, a beneficial gut probiotic that produces a GLP-1-inducing protein. As noted in one study:16
“A. muciniphila increases thermogenesis and glucagon-like peptide-1 (GLP-1) secretion in high-fat-diet (HFD)-induced C57BL/6J mice by induction of uncoupling protein 1 in brown adipose tissue and systemic GLP-1 secretion.”
Many people lack Akkermansia due to various reasons, such as impaired mitochondrial function or an environment that is inhospitable to beneficial gut bacteria. Ideally, Akkermansia should comprise 3% to 5% of your total gut microbiome and it plays many different roles aside from promoting GLP-1.
For example, Akkermansia has the ability to produce mucin, which is a thick, gel-like substance that protects the gut lining from harmful pathogens, irritation from stomach acid and enzymes, as well as mechanical damage. Moreover, mucin helps nourish the gut bacteria already existing in your gut.
To boost Akkermansia naturally, eat plenty of berries and inulin-rich foods such as garlic, asparagus, bananas and leeks. Note, however, that if your gut health is currently out of whack, introducing high amounts of dietary fiber in your system all at once can worsen your gastrointestinal symptoms. So, work on healing your gut first, then gradually increase fiber intake.

Carrageenan’s Gut Health and Insulin Risks
Reproduced from original article:
https://articles.mercola.com/sites/articles/archive/2025/02/05/carrageenans-gut-health-and-insulin-risks.aspx
Analysis by Dr. Joseph Mercola February 05, 2025
STORY AT-A-GLANCE
- Carrageenan, a common food additive, is linked to insulin resistance and gut inflammation by increasing intestinal permeability and promoting systemic inflammation
- A study found that carrageenan intake led to reduced insulin sensitivity and increased inflammatory markers in overweight participants, suggesting a disruption in gut barrier function
- Animal studies have shown that carrageenan causes intestinal lesions and promotes cancer, with degraded carrageenan being particularly associated with carcinogenic effects
- The mechanism by which carrageenan causes harm involves macrophage infiltration and lysosomal disruption, leading to inflammation and tumor formation
- Avoid processed foods to reduce your exposure to carrageenan, as many contain this toxic additive
Carrageenan, a common food additive used to enhance texture in products like dairy and meat, is under scrutiny for its health risks. This widespread ingredient, known scientifically as E 407, has been linked to insulin resistance and chronic inflammation in the gut.
Insulin resistance is a condition where your body’s cells don’t respond effectively to insulin, leading to elevated blood sugar levels. Characterized by fatigue, increased hunger and weight gain, insulin resistance is a precursor to Type 2 diabetes — a disease affecting millions worldwide. Research published in BMC Medicine highlights that carrageenan disrupts your body’s insulin sensitivity, especially if you carry extra weight.1
As carrageenan consumption has surged over the past decades, understanding its impact on metabolic health is important for public health. The BMC Medicine study underscores the need for caution regarding consumption of carrageenan-containing foods. Future research must further investigate the long-term health effects of carrageenan to ensure public safety and well-being.
Understanding Carrageenan’s Risks to Health
Carrageenan is commonly found in processed foods, particularly those marketed as low-fat or dairy alternatives. While carrageenan is used for its gelling and emulsifying properties, concerns have arisen about its impact on gut health and metabolic processes.
One primary concern is its ability to increase intestinal permeability, often referred to as “leaky gut.” This condition allows harmful substances to pass through your gut lining into your bloodstream, triggering systemic inflammation. Additionally, carrageenan has been shown to activate immune cells, leading to the release of proinflammatory cytokines.
These immune responses exacerbate existing health conditions, particularly in those already predisposed to metabolic disorders. The interaction between carrageenan and the gut microbiome is another area of concern, as it disrupts the balance of beneficial bacteria, further contributing to health issues.
Explaining how these underlying causes lead to health problems involves understanding your body’s complex response to carrageenan. When intestinal permeability increases, it sets off a chain reaction. Harmful substances that should remain confined to your gut enter your bloodstream, prompting the immune system to respond. This immune activation can lead to chronic inflammation, a known precursor to various diseases, including Type 2 diabetes.
The disruption of the gut microbiome also impairs digestion and nutrient absorption, compounding the negative effects on overall health. These processes illustrate how a seemingly innocuous food additive has far-reaching consequences.
Diagnosing issues related to carrageenan consumption is challenging. Many symptoms, such as digestive discomfort and fatigue, are nonspecific and attributed to numerous other conditions. This overlap makes it difficult for healthcare professionals to pinpoint carrageenan as the culprit.
The diagnostic process often falls short due to the complexity of symptoms and the limited awareness of carrageenan’s health impacts. Many healthcare providers don’t consider food additives as a primary factor in their assessments, focusing instead on more common dietary or lifestyle factors.
As research continues to uncover the risks associated with carrageenan, it becomes increasingly important for both healthcare providers and consumers to be informed about its health implications.
Carrageenan Intake Significantly Impacts Insulin Sensitivity and Gut Health
The BMC Medicine study investigated the effects of carrageenan on insulin resistance, subclinical inflammation and intestinal health in humans.2 The research specifically aimed to determine how carrageenan consumption influences metabolic processes and gut integrity, shedding light on its role in chronic health issues.
The study involved 20 young, nonobese men with an average age of 27.4 years and a body mass index (BMI) of 24.5.3 These participants were exposed to carrageenan or a placebo over a two-week period, with a subsequent washout period to assess the lasting impacts of the additive.
The findings indicated that carrageenan intake did not significantly alter overall insulin sensitivity; however, in overweight participants, it was associated with reduced whole-body and hepatic insulin sensitivity.4
Carrageenan was also found to increase intestinal permeability. This disruption of the intestinal barrier was evidenced by higher lactulose absorption and elevated circulating zonulin levels, a protein associated with gut permeability.5 The study noted that participants who consumed carrageenan showed a significant rise in zonulin levels compared to those who took a placebo, underscoring the compound’s impact on gut integrity.6
Furthermore, those exposed to carrageenan had a “trend towards increased brain inflammation, and elevated C-reactive protein (CRP) and IL-6 levels,” while carrageenan exposure also activated natural killer (NK) cells and increased the release of proinflammatory cytokines such as IL-6.7
These immune responses contribute to a state of subclinical inflammation, which is a precursor to various chronic diseases, including Type 2 diabetes. The activation of NK cells in response to carrageenan suggests that the additive plays a direct role in promoting inflammatory pathways within the body.8
The study also highlighted that carrageenan-induced insulin resistance was more pronounced in individuals with higher BMIs.9 Participants with higher body mass experienced a greater decline in insulin sensitivity and increased levels of inflammatory markers like CRP and IL-6 during carrageenan intake.10 This suggests that carrageenan may exacerbate metabolic issues in overweight individuals, leading to more severe health complications over time.11
In summary, this study provides compelling evidence that carrageenan consumption can significantly disrupt metabolic and intestinal functions, particularly in individuals with higher body mass. The additive’s role in increasing gut permeability and promoting inflammation underscores the need for further investigation into its long-term health effects.12

Carrageenan’s Harmful Effects on the Gastrointestinal System
A research review further investigated the adverse effects of carrageenan on the gastrointestinal systems of various animals. The research aimed to determine how carrageenan contributes to chronic inflammatory bowel disease, ulcers and even cancer in different animal models.13
The study utilized a diverse group of animals, including guinea pigs, rats, monkeys, mice, rabbits, and ferrets. These animals were exposed to both undegraded and degraded forms of carrageenan to assess its impact. The findings revealed a strong association between carrageenan consumption and the development of intestinal tumors and ulcerations. Notably, degraded carrageenan was identified as a potential carcinogen, raising significant health concerns.14
One of the most striking outcomes was the high incidence of colonic tumors in rats. When rats were fed a diet containing 10% degraded carrageenan for less than two years, 32% developed colonic tumors.15 Further, exposing animals to 5% degraded carrageenan in their drinking water resulted in a 100% incidence of colonic metaplasia after just 15 months. Colonic metaplasia refers to the abnormal transformation of cells in the colon, which is often a precursor to cancer.16
The study also highlighted the severe gastrointestinal lesions caused by carrageenan. In various animal models, carrageenan exposure led to the formation of polypoidal lesions and significant, irreversible changes in the rectal mucosa.
These ulcerative lesions closely resembled those seen in human ulcerative colitis, a chronic inflammatory condition of the colon.17 Such similarities suggest that carrageenan could trigger similar inflammatory processes in humans, leading to serious bowel diseases.
Carrageenan Breaks Down in Your Stomach, Posing Health Risks
Biologically, carrageenan undergoes a chemical transformation during digestion. In the acidic environment of your stomach, carrageenan breaks down into smaller molecules, known as degraded carrageenan, which are more harmful.18
This degradation increases carrageenan’s ability to penetrate your intestinal barrier, allowing it to reach deeper tissues and organs. Once inside your body, carrageenan causes epithelial cell loss and erosion, weakening your gut lining and making it more susceptible to infections and inflammation.19
One mechanism by which carrageenan induces these harmful effects is through macrophage infiltration. Macrophages are immune cells that respond to foreign substances in your body. When carrageenan is present, it attracts macrophages to the intestinal walls, leading to an inflammatory response. This inflammation not only damages your gut lining but also disrupts normal cellular functions, paving the way for tumor formation and chronic diseases.20
Another important aspect of carrageenan’s harmful action is its ability to cross your intestinal barrier and accumulate in lymph nodes. This accumulation further exacerbates immune responses, leading to systemic inflammation.21 Furthermore, carrageenan’s interaction with lysosomes, which are your cell’s recycling centers, leads to their disruption. When lysosomes are damaged, they release enzymes that break down cellular components indiscriminately.22
The study also noted that the harmful effects of carrageenan are dose-dependent and related to the duration of exposure. Higher doses and longer exposure periods resulted in more severe gastrointestinal damage and a higher likelihood of tumor development.23 This dose-response relationship underscores the importance of minimizing carrageenan intake to reduce your risk of chronic health issues.
The study’s findings have significant implications for human health, especially considering the widespread use of carrageenan in processed foods. The evidence from animal models strongly suggests that carrageenan consumption could lead to similar gastrointestinal problems in humans, including chronic inflammation and an increased risk of colorectal cancer.24 These results call for a reevaluation of carrageenan’s safety in food products to protect public health.
Simple Steps to Avoid Carrageenan and Protect Against Its Harmful Effects
To safeguard your cellular health from carrageenan’s detrimental impacts on insulin sensitivity and gut integrity, adopt a comprehensive strategy that eliminates carrageenan exposure while enhancing your body’s natural healing capabilities. Follow these steps:
1. Avoid processed foods — Eliminate processed foods from your diet, as many contain carrageenan. For processed foods you’re considering, carefully scrutinize their ingredient lists.
If carrageenan is listed, avoid the product and choose cleaner alternatives that align with optimal health guidelines. The Cornucopia Institute has an online guide to avoid carrageenan in organic foods.25 Also avoid carrageenan-containing supplements to further protect your health.
2. Make your own alternatives — Replace commercial dairy products, like yogurt, and creamy soups, which often contain carrageenan, with homemade versions. This approach ensures full control over ingredients, eliminating unnecessary additives. Use milk sourced from grass fed cows and natural thickeners like grass fed cream or pureed vegetables to achieve the desired texture and flavor without compromising your health.
3. Enhance your cellular energy production — Boost your body’s natural ability to maintain a healthy gut barrier by optimizing your mitochondrial function, which is essential for cellular energy production.
Your mitochondria produce adenosine triphosphate (ATP), the essential fuel that keeps your cells running and repairing themselves. Without energy, your cells can’t repair and regenerate themselves. So, the fundamental issue underlying most chronic disease is that your cells are not producing enough energy.
By avoiding mitochondrial poisons, including linoleic acid (LA) in seed oils, synthetic endocrine-disrupting chemicals (EDCs), estrogen and pervasive electromagnetic fields (EMFs), you protect your mitochondrial health and boost cellular energy, so your body is better able to recover from exposure to toxins like carrageenan.
