For decades, olive oil has been marketed as the gold standard of healthy fats — central to the Mediterranean diet and praised for its heart-protective benefits. It’s become a staple in health-conscious kitchens, drizzled over salads, blended into dressings, and splashed into sauté pans without a second thought.

But sometimes what’s widely accepted isn’t the whole story. Behind olive oil’s reputation is a single dominant fat: oleic acid. It’s a monounsaturated fat you’ll find not only in olive oil, but also in avocado oil and high-oleic seed oils. And it doesn’t just pass through your system unnoticed. Your body listens to it — and responds.

The story you’re about to read breaks open a new chapter in our understanding of dietary fat. What you pour on your plate goes beyond adding flavor. It sends a signal. And depending on the oil, that signal could be telling your body to store more fat, whether you’re overeating or not.

Oleic Acid Triggers New Fat Cell Growth

In a 2025 study published in Cell Reports, researchers tested different types of fats to see which ones led to more body fat — not just from eating too much, but from the fat itself acting like a trigger.1 They found that one fat in particular — oleic acid — stood out. The goal was to figure out if certain fats tell your body to create more fat cells, not just fill up the ones you already have.

• This study wasn’t about fat cells getting bigger — it was about your body making new ones — Most people think gaining fat means your current fat cells just get puffier. But this research looked at something more permanent: your body actually making more fat cells. Once that happens, those new cells don’t disappear when you lose weight. They stick around and make it easier to gain weight again later.

• Only oleic acid had this fat-boosting effect in both animals and humans — Mice fed oleic-acid-rich diets showed a sharp increase in precursor fat cells, the ones that turn into mature fat-storing cells. Human fat cells exposed to oleic acid in lab settings did the same thing. Other fats like coconut oil and stearic acid didn’t cause this change — only oleic acid did. Still, we need more replicated science to confirm that oleic acid does, in fact, cause obesity to a greater extent than other fats.

• Even with the same calories, olive oil caused more fat buildup — In one part of the study, mice were fed the same number of calories but from different types of fat. Those that got oleic-acid-heavy fats like olive oil gained significantly more fat — not because they ate more, but because their fat cells multiplied faster. That means fat variety, not just quantity, matters a lot.

• More oleic acid in your blood means more fat cells created — Blood tests showed a direct connection between oleic acid levels in the blood and how many new fat cells were created. The more oleic acid that showed up, the more new fat cells the body made. In other words, this fat acts like a signal telling your body to grow more storage space for fat.

Oleic Acid Flips Metabolic Switches That Tell Your Body to Store More Fat

Inside your cells, there’s a control system that decides whether to build new fat tissue. Oleic acid throws that switch to “on,” sending a signal that tells your body it’s time to grow more fat cells. When that switch isn’t working, this process doesn’t happen, showing that oleic acid relies on this internal command to get the fat-storing process moving.2

• Oleic acid shuts off your natural fat-limiting controls — Your body also has a built-in safety system that’s supposed to slow down or stop unnecessary fat cell growth. Think of it like a brake pedal that prevents you from creating more fat than you need. Oleic acid disables that brake, allowing fat cell development to go unchecked. The result is a steady stream of new fat cells being created, even when they’re not needed.

• Without that brake, fat cells multiply fast — In one part of the study, researchers looked at mice that had this fat-limiting brake permanently turned off. When those mice consumed oleic acid, they experienced an explosion of new fat cell growth, much more than normal mice. This shows that oleic acid doesn’t just promote fat storage, it also removes your body’s ability to say “enough.”

• Human studies confirmed what the animal studies showed — Using data from the UK Biobank, one of the largest health databases in the world, researchers found that high levels of monounsaturated fats in the blood, mostly oleic acid, were strongly linked to higher obesity risk. Out of 249 different blood markers tested, oleic acid had the strongest link to being overweight.

Why Healthy-Sounding Oils Aren’t Always Helping You

The study shows that oleic acid plays a bigger role in fat gain than most people realize. But there’s another layer to this problem — one that’s hidden in plain sight. The oils you trust as “healthy,” like olive and avocado oils, are sabotaging your metabolism in more ways than one.

• Let’s start with what’s actually in the bottle — Most people assume that if they’re buying olive oil, they’re getting the real deal. But research has repeatedly shown that many olive oils on the market are diluted or adulterated, often with cheap, highly refined vegetable oils like soybean or canola. So, unless you know your source, you’re likely getting a cocktail of inflammatory industrial fats with every pour.

• Concerns over olive oil aren’t new — I previously interviewed Brad Marshall, who’s done excellent work on reductive stress and has warned about the metabolic problems associated with oleic acid in olive oil, including increased risk of obesity and energy imbalance. That’s a huge red flag for anyone struggling with metabolic issues, energy dips, or weight that won’t budge.

• Too much oleic acid disrupts your mitochondria in similar ways as linoleic acid (LA) — While it isn’t a polyunsaturated fat like LA, oleic acid still embeds itself into your mitochondrial membrane and crowds out cardiolipin, a key fat that your mitochondria need to make energy efficiently.

When cardiolipin is displaced, the electron transport chain becomes unstable, leading to reduced adenosine triphosphate (ATP) production and increased oxidative stress. This same underlying mechanism is detailed in my 2025 Advances in Redox Research review, where I explain how both oxidative and reductive stress from fats like LA push mitochondria toward dysfunction and eventual breakdown.3

• Still holding onto the idea that olive oil is heart-healthy? This is partly true. It contains antioxidant-rich polyphenols that offer some protection. But those benefits don’t cancel out the downsides when you’re using olive oil liberally. When you strip away the antioxidants, oleic acid becomes a metabolic disruptor.

If olive oil is in your kitchen, it doesn’t mean you need to throw it out immediately. But it does mean you should stop treating it like a health food to pour freely. Your cells are listening to the signals you send them — make sure those signals are helping, not hurting.

How to Adjust Your Dietary Oils to Boost Your Well-Being

If you’ve been relying on olive oil as your go-to “healthy fat,” it’s time to rethink that habit. I used to recommend it too — until the research became too clear to ignore. Oleic acid has been shown to drive the creation of new fat cells, even without overeating. That means your body could be stockpiling fat just from the type of oil you use, not how much food you eat.

Here’s how you start undoing that damage by removing the cause, rebalancing your fat intake, and restoring your mitochondrial energy. The goal is to reduce oleic acid buildup and get your metabolism functioning the way it was designed to. If you’re struggling with stubborn belly fat, feel like your energy has flatlined, or notice fat creeping on even when you’re eating healthy, here’s what I recommend:

1. Don’t replace olive oil with vegetable oils — ditch both — You might think swapping olive oil for something labeled “vegetable oil” is a step in the right direction, but it’s not. Industrial vegetable oils like soybean, corn, canola, and safflower are worse than olive oil because they’re packed with LA, a highly inflammatory polyunsaturated fat that damages your mitochondria, drives oxidative stress, and stays in your body for years.

These oils break down into toxic byproducts that interfere with hormone signaling and fat metabolism. So don’t just replace one problem oil with another — remove both oleic- and LA-rich oils from your kitchen entirely.

2. Switch to metabolically stable fats like tallow, ghee, or grass fed butter — These traditional fats are lower in both oleic acid and LA and much more stable when heated. Use grass fed butter and ghee for cooking and keep tallow on hand for sautéing and roasting. These fats support mitochondrial energy production instead of disrupting it. They’re also more satisfying, which naturally helps regulate your appetite.

3. Eat meats from animals fed natural diets, not industrial feed — If you’re eating pork or chicken raised on high-LA feeds (like soy and corn), you’re still getting large doses of unhealthy fats. I recommend switching to ruminant meats like grass fed beef and lamb. These animals convert the fats in their feed differently and don’t store excess oleic acid the same way. Instead of chicken and pork, stick with wild game and grass fed beef.

4. Prioritize carbs and collagen — One of the biggest mistakes people make when removing olive oil is replacing it with more fat. That only compounds the problem. What your cells actually need is fuel in the form of easy-to-digest carbs like fruit, root vegetables, and white rice, alongside a steady supply of collagen-rich protein like bone broth or slow-cooked meats. This combo helps rebuild your cell membranes and repair fat-driven metabolic damage.

5. Track your fat intake like you track your carbs or protein — Most people don’t think twice about the kinds of fats they use day to day, but your body does. Start paying closer attention to how much oleic acid you’re getting, not just from olive oil but from foods like salad dressings.

Treat it like any other macro: something to monitor and balance. Use a simple food journal or app to log your daily fat sources for two weeks. You’ll quickly spot patterns — like how often olive oil or avocado oil sneaks into your meals.

Once you see it, you can start swapping it out with fats that actually support your metabolism. Awareness is the first step to change, and this simple tracking habit helps reconnect you with how your body responds to what’s on your plate. Fat is not the enemy. But the wrong fat, even in a “healthy” form, creates the wrong signals. Reset those signals, and your body will finally respond the way it’s supposed to.

FAQs About Olive Oil

Q: Is olive oil really causing weight gain, even if I eat healthy?

A: Yes, according to a 2025 study in Cell Reports, oleic acid — the main fat in olive oil — triggers the creation of new fat cells even without overeating.4 This helps explain why some people gain weight despite clean eating and calorie control.

Q: What makes oleic acid different from other fats?

A: Oleic acid doesn’t just store energy. It sends signals to your cells to make more fat-storing cells. Other fats, like stearic acid or coconut oil, didn’t have the same effect in studies. The issue isn’t just how much fat you eat, but what type.

Q: Isn’t olive oil part of the healthy Mediterranean diet?

A: It is, but moderation is key. Olive oil does contain protective polyphenols, but in excess, its main fat disrupts mitochondria, promotes fat storage, and interferes with metabolic health.

Q: Should I stop using olive oil completely?

A: Not necessarily, but you should stop treating it like a free-pour health food. Many store-bought olive oils are adulterated, and even pure versions are problematic in large amounts. Track how often you’re using it and consider switching to more stable fats like ghee, tallow, or grass fed butter.

Q: What’s the best way to fix this if I’ve been using olive oil for years?

A: Start by removing high-oleic oils from your kitchen and replacing them with metabolically supportive fats. Prioritize easy-to-digest carbs and collagen-rich proteins, and monitor your fat intake like you would any other nutrient. Over time, this shift restores mitochondrial function and helps normalize weight and energy levels.

If you’ve embraced a high-fat or ketogenic diet to protect your metabolism, research, published in The Journal of Nutrition, challenges that assumption.1 Within just two weeks, mice fed fat-heavy diets showed the first signs of metabolic damage — and the harm only deepened from there.

Metabolic dysfunction is characterized by rising fasting blood glucose, weight gain, elevated triglycerides, and fatty liver disease — meaning fat builds up inside your liver cells. Over time, that process drives inflammation, insulin resistance and scarring of liver tissue. What makes the Penn State results so striking is that all dietary groups consumed similar calories. The macronutrient ratio, not the calorie count, made the difference.

A separate investigation published in Molecular Cell adds another layer: high-fat feeding doesn’t just alter body composition — it rewires the chemical machinery inside your cells, disrupting the systems that govern energy production and oxidative stress, with effects that differ meaningfully between males and females.2

These findings raise a direct question: if high fat intake rapidly disrupts glucose control, liver health and cellular energy systems, what does that mean for the way you structure your plate? The controlled feeding data provide a clear starting point.

Fat-Heavy Diets Strained the Liver and Blood Sugar Control

For The Journal of Nutrition study, researchers designed three experimental diets with identical protein content but very different carbohydrate-to-fat ratios: a high-carbohydrate diet (70% carbohydrate, 11% fat), a high-fat diet (42% carbohydrate, 40% fat), and a ketogenic diet (1% carbohydrate, 81% fat).3 A whole-grain-rich chow diet served as the control. By holding protein steady, the researchers isolated the effect of swapping carbohydrates for fat.

• Normal-weight mice experienced rapid metabolic decline on high-fat and ketogenic diets — In lean mice, both the high-fat and ketogenic diets drove continuous weight gain and hyperglycemia, meaning elevated blood sugar levels.
Despite similar calorie intake across groups, mice on fat-rich diets nearly doubled their body weight over 16 weeks, while control mice gained only about 10%, which is typical growth for that age. Adverse changes began as early as week two. That short window underscores how rapidly dietary composition alters metabolic signaling.
• Liver damage appeared early and worsened over time — Within just two weeks, mice on high-fat and ketogenic diets showed impaired glucose tolerance and signs of compromised liver function. By 16 weeks, fat-rich diets promoted fat buildup inside liver cells, along with inflammation and fibrosis, which is scar tissue formation.
The high-carbohydrate group didn’t show the same pattern of liver injury. If you picture your liver as a metabolic control center, this level of fat accumulation slows its ability to regulate blood sugar and lipids efficiently.
• Triglycerides and inflammatory markers rose sharply under ketogenic conditions — Mice on the ketogenic diet developed elevated triglycerides, a blood fat linked to heart disease risk. They also expressed genes associated with inflammation and liver scarring. That shift matters because inflammation accelerates metabolic dysfunction. The study makes clear that nutritional ketosis didn’t shield the liver from harm in this model.
• Whole-grain chow produced the strongest health markers — Among all groups, the whole-grain-based chow resulted in the best metabolic profile, including stable weight gain and healthier liver markers.
Even the high-carbohydrate diet outperformed both fat-rich diets in preserving liver integrity. In obese mice, switching to chow or a high-carbohydrate diet improved markers of inflammation, liver health and metabolic stress within two weeks. If your goal is metabolic stability, this comparison highlights how extreme fat intake stacks up against carbohydrate-dominant patterns.
• Fiber softened the metabolic blow of a ketogenic diet in obese mice — In a second phase, researchers tested obese mice that had already developed metabolic dysfunction. When inulin, a type of prebiotic fiber, was added to the ketogenic diet, some adverse immunometabolic markers improved compared to ketogenic or high-fat feeding alone. Importantly, fiber enrichment did not block ketone production.
That finding gives you a practical takeaway: gut-supportive carbohydrates influence how your body responds to fat-heavy diets.

High-Fat Diets Change How Your Cells Run at the Smallest Level

Those visible metabolic injuries — the fatty liver, the spiking blood sugar — have roots at a much deeper level. A second study, published in Molecular Cell, reveals what’s happening inside the cell itself.4 It examined how eating a high-fat diet alters tiny chemical tags on proteins in mice.

These tags work like dimmer switches on your cellular machinery — they don’t just turn processes on or off, they fine-tune how intensely each one runs. The researchers studied these switches to see how too much fat changes how cells make and use energy. Their goal was to show how excess fat reshapes the way your cells function.

• Male and female bodies reacted differently — Both male and female mice gained weight on a high-fat diet, but males gained more body fat overall. Their blood sugar rose more sharply, and their insulin levels increased significantly, which signals stronger insulin resistance. Females also gained weight and had higher blood sugar, but the damage wasn’t as severe.
• Hundreds of chemical markers inside the liver shifted — The researchers measured 260 different small molecules in the liver and found hundreds of protein switch changes linked to metabolism. Diet explained a large portion of these shifts, and sex explained another significant portion. In simple terms, what the mice ate and whether they were male or female strongly influenced how their cells processed fuel.
• The body’s stress and antioxidant systems were hit hard — Many of the altered switches involved enzymes that control glutathione, one of your body’s main antioxidants. Antioxidants protect your cells from damage caused by excess fuel and stress.
The study found that high-fat feeding changed the position of these switches near key working areas of the enzymes. When these switches are flipped by excess fat, your cells lose some of their ability to neutralize damage and process fuel cleanly — leaving them more vulnerable to the very stress that high-fat diets create.
When researchers added an antioxidant to the high-fat diet, body weight dropped by about 47%, blood sugar fell by about 47%, and insulin levels decreased nearly 10-fold compared to high-fat feeding alone. Many of the disturbed chemical markers shifted back toward healthier patterns. This shows that oxidative stress plays a major role in the damage caused by excess fat.
• Certain enzyme switches created traffic jams inside cells — Some of the chemical switches slowed down important energy pathways. For example, one switch boosted a backup energy pathway used when mitochondria are strained. Another switch slowed the production of building blocks needed for DNA and cell repair. When these processes slow down or reroute, your cells lose efficiency and stability.
Lab experiments confirmed that changing these protein switches directly altered how enzymes worked. Some switches reduced enzyme activity by 20% to 30%. Others boosted certain stress-driven energy pathways. This means high-fat diets do more than increase body fat. They change how your cells produce and protect energy at the molecular level.

Restore Metabolic Balance by Lowering Excess Fat and Rebuilding Cellular Energy

High fat intake disrupts blood sugar control, strains your liver and rewires the chemical switches that govern cellular energy. If you want to reverse that trajectory, you need to correct the root driver: excessive dietary fat overwhelming your metabolic system. Focus first on reducing that burden while restoring the nutrients and signals that allow your mitochondria — the energy engines inside your cells — to function efficiently. Here is how you begin.

1. Optimize your macronutrient balance — lower fat, restore carbs — The research shows that when fat intake climbs too high, metabolic stress markers rise and cellular energy systems shift in harmful ways. When your cells burn mostly fat for fuel, the process generates more oxidative byproducts and sidelines the cleaner glucose-burning pathways your mitochondria prefer. I recommend keeping your total fat intake between 30% and 40% of your daily calories.

2. Eliminate seed oils and excess linoleic acid (LA) completely — The bigger issue isn’t just total fat — it’s LA, a polyunsaturated fat concentrated in seed oils. Excess LA intake disrupts mitochondrial function, drives oxidative stress and strains your liver. Remove canola, corn, soybean, safflower, sunflower, and grapeseed oils from your kitchen. Eliminate nuts, seeds, and nut butters, which are also high in LA. Replace those fats with saturated fats such as grass fed butter, ghee or tallow.
Even olive and avocado oil deserve moderation. They’re often diluted with cheaper seed oils and are rich in monounsaturated fats that still burden mitochondrial energy systems when consumed in excess. Lowering your LA intake reduces inflammatory stress and restores more stable cellular fuel processing.
The goal is to get your LA intake below 5 grams, and ideally closer to 2 grams, daily. To track your intake, download the upcoming Mercola Health Coach app, which includes the Seed Oil Sleuth feature that calculates LA exposure with precise accuracy.

3. Increase carbohydrates to about 250 grams per day — Under normal conditions, your cells generate energy most efficiently when glucose is available as a primary fuel. Most adults thrive on 250 grams of carbohydrates daily, more if you’re active. 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.

4. Rebuild your gut environment before increasing fiber aggressively — The first study showed that fiber improved outcomes in high-fat feeding. However, if your microbiome is damaged, fiber feeds the wrong bacteria, increasing endotoxin load. That’s why it’s important to repair your gut lining first before increasing fiber.
Start by removing the main irritants. Eliminate seed oils, processed foods, alcohol and excessive fat. These disrupt your intestinal barrier and increase oxidative stress. Your gut lining is a thin layer of cells held together by tight junctions. When those junctions loosen, bacterial toxins enter your bloodstream and trigger inflammation.
Next, support the cells that line your colon. These cells rely on stable energy production. Gradually increase easily digested carbohydrates like whole fruit and white rice to restore mitochondrial function. Adequate glucose supports proper cell turnover and strengthens your intestinal barrier.
Short-chain fatty acids, especially butyrate, play a central role here. Butyrate is produced when beneficial bacteria ferment certain fibers. It serves as the primary fuel for colon cells and helps tighten the junctions between them. When butyrate levels are low, your gut barrier weakens. As your digestion improves, introducing small amounts of the right fibers encourages healthy bacteria to produce butyrate, which reinforces the lining from the inside out.
Then rebuild protective mucus and beneficial bacteria. Collagen-rich protein like bone broth helps provide glycine, which supports tissue repair and glutathione production. Consider introducing small amounts of targeted prebiotic fiber such as inulin only after fat intake is reduced and digestion improves. Increase fiber slowly. If bloating, pain or loose stools appear, back down and proceed gradually.

5. Support redox balance with sunlight and cellular energy tools — Redox balance refers to the tug-of-war between damaging molecules and the protective antioxidants that neutralize them. It depends on efficient mitochondrial function. Sunlight stimulates nitric oxide release and supports mitochondrial energy production, improving your cells’ ability to manage oxidative stress.
Gradual, consistent sun exposure strengthens this system. However, if your body is full of LA from years of seed oil consumption, your skin is more prone to burning during midday sun. Avoid sunlight from 10 a.m. to 4 p.m. until you’ve reduced seed oils for at least six months, focusing instead on morning and late afternoon light. Once your tissues are free from these unstable fats, you’ll tolerate more sun safely.

If you’ve relied on high-fat dietary strategies for weight control, this transition to lower fat, higher carbs restores metabolic flexibility rather than suppressing it. Each small adjustment builds momentum. Your liver and cellular energy systems respond quickly when the overload is removed.

FAQs About High-Fat Diets and Metabolic Health

Q: Did the research show that high-fat diets caused more harm than high-carbohydrate diets?
A: Yes. In The Journal of Nutrition study, mice consuming high-fat and ketogenic diets developed rapid weight gain, elevated blood sugar and measurable liver damage, while the high-carbohydrate group didn’t show the same degree of liver injury.5 All groups consumed similar calories. The difference came from the macronutrient ratio, not calorie intake.

Q: How quickly did metabolic damage appear on high-fat diets?
A: Signs of metabolic dysfunction appeared within just two weeks. Mice on high-fat and ketogenic diets showed impaired glucose tolerance and early liver stress at that point. By 16 weeks, fat accumulation, inflammation and fibrosis were clearly present in the liver. The damage developed quickly and deepened over time.

Q: What happened inside the cells on a high-fat diet?
A: The second study, published in Molecular Cell, showed that high-fat feeding altered chemical “switches” on metabolic enzymes.6 These switches control how your cells produce energy and manage oxidative stress. High fat intake disrupted antioxidant systems, redox balance and key energy pathways, especially in male mice. This means excess fat changes how your cells function at the molecular level, not just how much body fat you store.

Q: Did anything reverse the damage caused by high-fat feeding?
A: Yes. When researchers added an antioxidant to the high-fat diet in the second study, body weight dropped by about 47%, fasting blood glucose fell by roughly 47%, and insulin levels decreased nearly 10-fold compared to high-fat feeding alone. Many disrupted metabolic markers shifted back toward healthier patterns, showing that oxidative stress played a central role in the damage.

Q: What practical steps help protect metabolic health?
A: The core strategy is lowering excessive fat intake while restoring balanced carbohydrate intake. Keeping total fat between 30% and 40% of daily calories, eliminating seed oils and reducing LA intake help reduce oxidative stress. Increasing carbohydrates to around 250 grams per day for most adults supports mitochondrial energy production. Supporting gut health and regular sunlight exposure further stabilizes redox balance and cellular energy systems.

If you’re tired all the time, gaining weight despite eating healthy, or struggling through brain fog that won’t lift, your thyroid could be the main problem. Thyroid issues like hypothyroidism are far more common than most people realize. In the United States alone, more than 20 million people have a thyroid disorder, and about 60% are not even aware that they have it.1

A sluggish thyroid can present in surprisingly common ways, and having a basic understanding of what the thyroid does and why it matters can make a big difference in recognizing when something feels off and addressing it early, especially now that researchers are uncovering how simple, structured movement practices may help support healthier thyroid function.

A Small Gland with a Big Impact

Your thyroid is a small, butterfly-shaped gland located at the base of your neck. But despite its size, it plays a big role in nearly every physiological process in your body. To do its job, the thyroid uses iodine, an essential mineral, to produce thyroid hormones, the primary ones being triiodothyronine (T3) and thyroxine (T4).2,3 These hormones set the pace of your metabolism — they tell every cell in your body how fast to burn fuel and produce energy.

Because energy production underlies nearly every biological process, thyroid hormones influence metabolism, heart rate, body temperature, mood, and digestion. When the thyroid falls out of balance, the effects can ripple across your entire body — and that imbalance can go in either direction. So when the thyroid stops working smoothly, it can affect your well-being in many ways, either by becoming underactive or overactive.

• Hypothyroidism is the most common thyroid disorder — Nearly five out of 100 Americans age 12 and older have hypothyroidism,4 a condition wherein the thyroid is underactive and not producing enough T3 and T4.5 Symptoms include fatigue, weight gain, constipation, dry skin, hair thinning, feeling cold, brain fog, and low mood.

• The brain tries to compensate — When thyroid hormone levels drop, your pituitary gland releases more thyroid-stimulating hormone (TSH), essentially signaling the thyroid to pick up the pace. Elevated TSH levels on a blood test often signal hypothyroidism. Women are at higher risk of this condition because of hormonal shifts during pregnancy, menopause, and autoimmune conditions such as Hashimoto’s thyroiditis.

• Hyperthyroidism is the opposite problem — Hyperthyroidism, or an overactive thyroid, happens when your thyroid makes too much hormone. It speeds everything up in the body, which can lead to symptoms such as a fast heartbeat, weight loss, increased hunger, and feeling on edge. The good news: it’s usually very treatable with medication.6

• Untreated thyroid disease can affect the entire body — Because symptoms like fatigue, weight changes, and mood shifts are so common, thyroid disorders frequently get mistaken for stress, aging, or depression. Over time, untreated low thyroid function may contribute to heart disease, infertility, muscle weakness, bone thinning, and severe metabolic slowdown. Other symptoms of hypothyroidism include:7

◦ Sensitivity to cold
◦ Hoarse voice
◦ Thinning hair
◦ Constipation
◦ Coarse hair and skin
◦ Depression

◦ Dry skin
◦ Muscle weakness, aches, and stiffness
◦ Memory problems
◦ Puffy face
◦ Irregular or heavy menstrual cycles

To better understand how deeply thyroid signaling shapes metabolism, mood, and long-term health, read “Your Thyroid Is the Regulator of Your Entire Existence.” With the importance of optimal thyroid health in mind, the next question becomes: What can you actually do to support it? Emerging evidence suggests yoga may be part of that answer.

Yoga May Improve Thyroid Health and Hypothyroidism Symptoms

A 2024 systematic review published in the Journal of Ayurveda and Integrative Medicine explored whether yoga influences thyroid function, symptoms, and overall well-being in people with hypothyroidism. The researchers analyzed 11 clinical trials involving 516 adults ages 18 to 65, with interventions lasting one to six months, to assess which structured yoga protocols were associated with measurable improvements.8

• Participants followed structured routines — Depending on the study, sessions included yoga postures (asanas), Sun Salutations (Suryanamaskar), breathing practices (pranayama), meditation, relaxation techniques, energy locks (bandhas), hand gestures (mudras), and in one case, a yoga-based bio-energy method. These practices were performed several times per week, with consistency emphasized across all studies.

• Researchers measured more than just thyroid labs — They also looked at hormone levels, cholesterol, blood sugar, weight, mood, sleep, breathing function, and even medication use. This provided a more comprehensive picture of how yoga affects the whole body.

• Yoga helped improve thyroid hormone balance — Most of the studies found that TSH decreased toward healthier ranges after regular yoga practice, suggesting the thyroid was working better on its own and the brain no longer needed to push it as hard. T3 and T4 levels also stabilized.

• There were also reduced levels of antithyroid antibodies — In Hashimoto’s thyroiditis, the body’s immune system mistakenly attacks the thyroid gland over time. One trial found that markers of this immune attack (called antithyroid peroxidase antibodies) decreased after yoga sessions. This suggests yoga could influence the underlying autoimmune process on the gland.

• Cholesterol and blood fat levels improved as well — Markers of heart disease, such as total cholesterol, low-density lipoprotein (LDL, often called “bad” cholesterol), and triglycerides decreased with yoga. On the other hand, high-density lipoprotein (HDL, the “good” cholesterol that helps clear excess fat from the bloodstream) increased. Because hypothyroidism often disrupts fat metabolism, these shifts reflect healthier cardiovascular function.

• Body weight and abdominal measurements decreased — Body mass index (BMI), weight, and waist circumference were reduced with consistent yoga practice. Since hypothyroidism commonly slows metabolism and contributes to weight gain, these changes suggest improved metabolic efficiency.

• Improved blood sugar control — One randomized trial found a meaningful drop in fasting blood sugar, even though hemoglobin A1c (HbA1c) — the three-month average of blood sugar — didn’t change much. This is important because hypothyroidism can slow metabolism and impair glucose regulation, so even early improvements may help overall balance.

• Participants needed less thyroid medication — One study reported that some participants were able to reduce their dosage of levothyroxine (LT4), the synthetic thyroid hormone prescribed for hypothyroidism, after six months of yoga. In contrast, medication use increased in comparison groups that did not practice yoga.

This is important because reduced medication use suggests that the body may be using thyroid hormone more efficiently rather than relying entirely on a higher replacement dose.

• Multiple studies also reported other positive changes — Researchers observed reductions in depression, anxiety, and stress, along with improvements in energy, daily functioning, and emotional well-being. One trial also reported better sleep and decreases in specific symptoms many hypothyroid patients find most disruptive, such as fatigue, cold intolerance, dry skin, and constipation.

Yoga’s breathing practices (pranayama) also appeared to strengthen both lung capacity and the body’s ability to shift between stress mode and recovery mode — a balance that tends to be off in people with hypothyroidism.

While this review focused on health changes observed after yoga practice, the next review examines how yoga may affect stress levels, nervous system balance, and long-term metabolic health in individuals with hypothyroidism.

Yoga May Support Thyroid Health by Regulating Stress and Metabolism

Another systematic review published in Annals of Neurosciences9,10 analyzed eight interventional studies on yoga and hypothyroidism. Rather than focusing only on thyroid lab values, this analysis emphasized how yoga may influence the nervous system, breathing capacity, and broader physiological regulation.

• Yoga helped the body handle stress more easily — After practicing yoga, participants showed better heart rate variability (HRV), a marker of how smoothly the body can shift between stress mode and relaxation mode. In simple terms, their bodies became better at calming down after stress and returning to a steady, relaxed state.

• Breathing strength and lung function improved — People who practiced structured breathing exercises had stronger lungs and could take in and move air more effectively. These improvements suggest better oxygen flow, stronger breathing muscles, and easier, more efficient breathing overall.

• Stress response systems may be modulated — The review found that yoga may help regulate the hypothalamic-pituitary-adrenal (HPA) axis, the body’s main stress-response pathway. This system works like an internal stress thermostat, controlling how much cortisol — the stress hormone — the body releases.

When the HPA axis is better balanced, cortisol levels tend to drop, and the body can shift out of “stress mode” more easily, leading to steadier mood, calmer reactions, and a more stable nervous system.

• Inflammatory and immune markers may shift toward balance — Yoga has been associated with reductions in inflammatory signals and improved immune cell activity, which may be relevant because autoimmune dysfunction is a common driver of hypothyroidism.

By highlighting the autonomic and hormonal pathways yoga appears to influence, this review reframes it not just as therapy but as a preventive tool. The next review takes that broader lens even further — examining how yoga affects not only hypothyroidism but multiple thyroid conditions.

How Different Thyroid Conditions Respond to Different Yoga Practices

While the previously discussed studies focused mainly on hypothyroidism, this 2022 review published in the BLDE University Journal of Health Sciences11,12 asked a broader question: Can yoga change thyroid hormone levels — T3, T4, and TSH — in different thyroid conditions? To answer this, researchers reviewed 11 experimental studies, which included participants with hypothyroidism, hyperthyroidism, and low T3 syndrome.

• People with hyperthyroidism had lower T4 levels — In the study on overactive thyroid, yoga was linked to a reduction in elevated T4 levels. This suggests yoga may help calm excess thyroid activity.

• Those with low T3 syndrome showed improved T3 levels — People with low T3 syndrome, a condition often triggered by illness or stress, showed improvements in T3 after practicing yoga.

• Participants with hypothyroidism showed reduced TSH levels — As seen in earlier reviews, people dealing with an underactive thyroid often experienced decreases in TSH after yoga practice.

• Neck-focused poses and slow breathing were commonly used — Studies that reported hormone changes often included poses where the neck is bent or extended, such as lying on the back with the legs lifted overhead or the chin tucked toward the chest.

Some also included a slow, controlled breathing technique that slightly narrows the throat to regulate airflow. One study using only a repeated hand gesture also reported measurable hormone shifts.

Taken together, these three reviews suggest that yoga may help support thyroid hormone balance across different thyroid states. The evidence is encouraging, but not yet definitive; larger, well-designed clinical trials are still needed before yoga can be formally integrated into thyroid treatment guidelines.

Beginner-Friendly Yoga Poses to Support Thyroid Health

While no pose can “fix” a thyroid condition on its own, certain movements improve posture, circulation, breathing patterns, and nervous system balance. The following poses from an article by Medical News Today13 can help with thyroid function. They may support healthy blood flow, reduce tension, and can be practiced at home with minimal equipment.

• Bridge Pose (Setu Bandha Sarvangasana) — This gentle backbend strengthens your back and opens the front of your neck and chest, helping improve posture and reduce tightness around the throat area.

1. Lie on your back with knees bent and feet flat on the floor, hip-width apart.
2. Press your feet into the mat and slowly lift your hips toward the ceiling.
3. Keep your chin gently tucked and your neck long.
4. Hold for three slow breaths.
5. Lower your hips slowly back down.

• Cobra Pose (Bhujangasana) — This pose gently stretches the front of the neck and encourages spinal flexibility.

1. Lie face down with your palms under your shoulders and your legs extended behind you.
2. Press gently into your hands and lift your chest off the mat.
3. Keep your elbows slightly bent and shoulders relaxed.
4. Lift only as high as feels comfortable.
5. Take three slow breaths, then lower down.

• Fish Pose (Modified Matsyasana) — This is a mild chest opener that can be done without deep back bending.

1. Sit with legs extended or cross-legged.
2. Place your hands behind you on the floor.
3. Gently lift your chest and tilt your head back slightly.
4. Keep the movement small and controlled.
5. Take five slow breaths, then return upright.

• Boat Pose (Modified Navasana) — This strengthens your core and supports upright posture, reducing strain on the neck and upper spine.

1. Sit on the floor with your knees bent and feet flat. Roll your shoulders back to open your chest.
2. Lean back slightly and lift your feet off the floor, keeping your knees bent.
3. Extend your arms forward, parallel to the floor.
4. Keep your chest lifted and your back straight — avoid rounding your spine.
5. Hold for five breaths, then lower your feet back down.

• Gentle Neck Stretch (Simple Seated Variation) — This reduces tension in the muscles surrounding the thyroid area and improves mobility.

1. Sit upright in a chair or on the floor.
2. Slowly tilt your head to one side, bringing your ear toward your shoulder.
3. Hold for three slow breaths.
4. Return to center, then repeat on the other side.

Supporting your thyroid doesn’t require mastering complicated poses or dramatic inversions. It’s about consistency, circulation, and calming the systems that quietly influence hormone balance every day. Gentle movement, steady breathing, and better posture may seem simple — but simple practices, done regularly, create meaningful change.

Safe and Natural Ways to Support Metabolic and Thyroid Function

Understanding the effects of yoga on thyroid health points to something deeper: Thyroid function doesn’t operate in isolation. It depends on how well-fueled, how calm, and how balanced the rest of your body is. Improving thyroid function isn’t about chasing lab numbers or piling on supplements — it’s about removing the roadblocks to energy production and giving your body steady, appropriate fuel. When you consistently address those root causes, meaningful progress follows.

• What are metabolic “brakes”? These so-called “brakes” are lifestyle, dietary, hormonal, or environmental factors that slow thyroid hormone activation and reduce cellular energy production. They increase reverse T3 (rT3) — an inactive form of thyroid hormone that blocks T3 from doing its job — reduce active T3 and signal the body to conserve energy instead of producing it. Before rebuilding metabolism, these brakes need to be identified and lowered.

• Release the metabolic brakes — Several common factors can blunt thyroid signaling and energy production. Systematically lowering these stressors helps T3 reach your cells:

◦ Manage stress — Chronic activation of the hypothalamic-pituitary-adrenal (HPA) axis raises cortisol, which impairs T4-to-T3 conversion and elevates rT3. Reduce unnecessary stressors (over-exercising, under-fueling, frequent fasting, and daily ice baths) and schedule recovery so you spend time in a parasympathetic, “rest-and-digest” state.

◦ Eat properly and nourish your body — If your body is suppressing T3, there’s usually a reason — low-quality food, chronic undereating, or stressors your system reads as “famine.” Start with what you’re currently doing. If you’ve been under-eating, increase calories gradually.

◦ Get some steps in — Maintain daily activity at approximately 7,000 to 8,000 steps, up to 12,000 if well tolerated, and include two to three strength-training sessions per week. Build gradually instead of making extreme changes. The first step is identifying what’s blocking proper thyroid signaling.

◦ Limit polyunsaturated fats (PUFs) — High intake of PUFs, especially linoleic acid (LA) commonly found in seed oils, may interfere with thyroid hormone transport proteins and reduce efficient delivery of active triiodothyronine (T3) to cells. Excess PUFs can also disrupt estrogen detoxification pathways, which may further impair thyroid signaling.

Limit industrial seed oils, including olive and avocado oils, as well as nuts and seeds, and conventional chicken and pork. Prioritize stable fats like butter, beef tallow, and pasture-raised options when available. If lower-PUF poultry and eggs aren’t accessible, limit eggs to two per day and choose leaner cuts of chicken and pork.

◦ Address estrogen dominance — Excess estrogen raises thyroxine-binding globulin (TBG),14 which ties up T3 and lowers the free, active fraction.15 Reduce exposures by choosing cleaner personal-care products and foods, and by keeping PUF intake in check to support estrogen detox.

◦ Reduce phytoestrogen intake — Phytoestrogens (notably from soy and flax) can mimic estrogen and may disrupt thyroid function16,17 and hormone availability. Limit soy milks and tofu, flax-heavy breads and supplements.

◦ Improve gut health — Roughly one-fifth of T4-to-T3 conversion occurs in the gut. Minimize additives, gums, and hard-to-digest foods; emphasize simple, well-tolerated, minimally processed meals and cooking methods that work for you.

• Equip your body with the right tools — Once brakes are reduced, your thyroid needs steady inputs.

◦ Adequate calories and micronutrients — Your cells produce energy in the form of adenosine triphosphate (ATP) inside mitochondria — the tiny power plants in every cell. This process requires sufficient calories plus minerals such as selenium, iodine, zinc, and vitamins including B vitamins and fat-soluble vitamins. Chronic calorie restriction slows energy production.

◦ Dietary carbohydrates — Carbohydrates support conversion of T4 into active T3 and prevent chronically low blood sugar, which increases reverse T3. Include carbohydrates you digest well each day.

◦ Balanced protein intake — Protein is essential, but relying heavily on muscle meat alone may create amino acid imbalance. Include glycine-rich sources such as collagen, gelatin, bone broth, or gelatin-rich cuts (oxtail, beef shank) alongside nutrient-dense proteins like eggs and dairy.18

In short, eat enough, eat well, manage stress, reduce inflammatory fats, and give your gut the conditions it needs to convert T4 into active T3. These steps help create an internal environment where thyroid hormones can do their work. To know more about how you can improve your thyroid function, read “A Comprehensive Guide to Thyroid Function and Metabolic Wellness.”

With these metabolic roadblocks addressed, the yoga practices described earlier in this article become even more effective; the body is better positioned to benefit from improved circulation, posture, and nervous system balance.

Frequently Asked Questions (FAQs) About Thyroid Health and Yoga

Q: What is hypothyroidism?
A: Hypothyroidism occurs when your thyroid, a small gland at the base of your neck, doesn’t produce enough T3 and T4, the hormones that regulate metabolism. Common symptoms include fatigue, weight gain, brain fog, and feeling cold.

Q: How common is hypothyroidism?
A: Thyroid problems like hypothyroidism are far more common than most people realize. In the United States alone, more than 20 million people have a thyroid disorder, and about 60% don’t even know they have it.

Q: What did the 2024 Journal of Ayurveda and Integrative Medicine review find?
A: A systematic review published in the Journal of Ayurveda and Integrative Medicine found yoga improved thyroid-stimulating hormone (TSH), cholesterol markers, heart rate variability (HRV), and sometimes reduced levothyroxine dosage, though study quality was mixed.

Q: What type of yoga is best for thyroid support?
A: The studies reviewed included a mix of gentle postures (asanas), breathing practices (pranayama), relaxation techniques, meditation, and in some cases hand mudras. Programs that combined movement with slow breathing and stress-reduction techniques appeared to produce broader benefits than posture alone. Neck-focused poses and structured breathing exercises were commonly included in protocols associated with hormonal improvements.

Q: What are metabolic “brakes”?
A: Metabolic brakes are stressors like chronic under-eating, elevated cortisol, high polyunsaturated fats (PUFs), estrogen dominance, gut dysfunction, or certain medications that increase reverse T3 (rT3) and reduce active T3 at the cellular level.

Your gut shapes more than just digestion — it’s a densely populated microbial hub where trillions of organisms break down food components. In doing so, they generate bioactive compounds that influence nearly every aspect of your health. One of the most important is butyrate, a short-chain fatty acid (SCFA) that serves as the main energy source for the cells lining your colon (colonocytes).1

Your ability to make butyrate depends on a stable population of beneficial gut bacteria. When this balance is disrupted by dietary choices or environmental toxins, your gut loses its ability to ferment fiber efficiently, and butyrate production decreases. The protective effects that butyrate provides fade with it. To regain those benefits, you have to support your body’s capacity to produce it.

Health Benefits of Butyrate

When your gut produces adequate butyrate, the benefits extend far beyond your digestive health. Understanding what butyrate does helps explain why supporting its production matters so much for long-term health. Its benefits include:2

• Reinforcing your gut barrier — Butyrate provides up to 70% of the energy that colonocytes need to function properly, allowing these cells to maintain tight junctions between them and producing the protective mucus layer that keeps harmful substances from crossing into your bloodstream.

When butyrate levels drop, your gut lining becomes more permeable, allowing partially digested food particles and bacterial components to trigger immune responses.3

• Lowering inflammation — Butyrate inhibits nuclear factor kappa B (NF-κB), a protein complex that activates inflammatory pathways throughout your body. NF-κB is often chronically activated in people with autoimmune conditions, gut disorders, and metabolic disease.4 Butyrate also inhibits the NLRP3 inflammasome, another key driver of inflammation that responds to cellular stress and injury.5

In addition to blocking inflammatory signals, it also boosts the production of interleukin-10 (IL-10), a powerful anti-inflammatory cytokine that tells immune cells to stand down.6 Moreover, studies show that butyrate reduces circulating C-reactive protein (CRP), a marker of systemic inflammation that’s elevated in a wide range of chronic diseases.7

• Regulating immune activity — Your immune system needs to strike a delicate balance — stay alert to real threats without overreacting to harmless stimuli. Butyrate plays an important role in maintaining this balance. When produced in sufficient amounts, it influences the behavior of immune cells, encouraging the growth of regulatory T cells (Tregs) that promote tolerance and suppress overactive responses.8,9

• Protecting brain health — Butyrate supports the gut-brain axis by reducing neuroinflammation and preserving the physical integrity of the blood-brain barrier. This barrier is a specialized structure that keeps harmful substances in the bloodstream from reaching the brain.

It also acts on microglia, the brain’s resident immune cells, helping to suppress their overactivation. Chronic microglial activation has been implicated in anxiety, depression, and neurodegenerative diseases like Parkinson’s and Alzheimer’s.

Additionally, butyrate influences the production of neurotransmitters such as serotonin and gamma-aminobutyric acid (GABA), which help regulate sleep. Animal studies suggest that increasing butyrate levels may improve symptoms of anxiety and support recovery from chronic stress and inflammation that affect the central nervous system.10

• Improving insulin sensitivity and metabolism — Butyrate plays a direct role in metabolic regulation by enhancing insulin sensitivity and supporting stable blood sugar control. It also stimulates the secretion of glucagon-like peptide-1 (GLP-1), a hormone that slows gastric emptying, reduces appetite, and improves blood sugar control after meals.11,12

• Supporting a healthy weight — Butyrate helps regulate hunger signals and metabolic efficiency, both of which influence how your body stores or burns fat. Its ability to stimulate GLP-1 not only improves blood sugar regulation, but also helps curb appetite, reduce food intake, and delay hunger between meals.13,14

• Lowering colorectal cancer risk — In the colon, butyrate promotes apoptosis (cell self-destruction) in precancerous and cancerous cells, helping reduce the risk of colorectal cancer. It also supports healthy cell turnover and differentiation, both of which are necessary to prevent abnormal growths in the intestinal lining.15

Foods That Enhance Butyrate Production

The most effective way to increase butyrate is to provide the raw materials your gut bacteria need to make it. Key producers like Faecalibacterium prausnitzii, Roseburia, and Eubacterium rely on specific dietary inputs to thrive. However, not all fibers ferment the same way, and not every gut can handle them equally. You’ll learn how to prepare your gut in the next section, but these are the foods that form the foundation of butyrate production:

• Begin with simple, well-tolerated carbs — In a disrupted gut, easily digested starches, such as cooked and cooled white rice and sweet potatoes as well as ripe, whole fruits, offer the gentlest way to support butyrate production. They help regulate digestion, stabilize blood sugar, and nourish both your colon lining and beneficial microbes without triggering gas, bloating, or discomfort.

• Gradually expand to prebiotic-rich foods — Once simple carbs are well tolerated, you can start layering in foods that offer more complex fermentable fibers and oligosaccharides. These act as prebiotics, which are nondigestible food components that selectively feed beneficial gut bacteria.16

◦Garlic
◦Onions
◦Asparagus
◦Chicory root
◦Jerusalem artichokes
◦Green bananas

◦Turnip greens
◦Broccoli
◦Carrots
◦Cooked oats
◦Seaweed and microalgae
◦Legumes (soaked or pressure-cooked peas, lentils, and beans)

• Add fermented foods to support microbial stability — Fermented foods don’t produce butyrate themselves, but they help shape the terrain that makes it possible. By delivering live organisms and metabolic byproducts, they strengthen your gut lining and help crowd out problematic strains. These include:

◦Sauerkraut
◦Kimchi
◦Kefir
◦Plain, full-fat yogurt
◦Fermented pickles

Introduce these into your diet slowly and in small amounts. Their microbial density makes them highly active, so monitor how you respond to each one individually.

• Include direct food sources of butyrate — While building up fermentation capacity, it also helps to supply butyrate directly through food. Full-fat dairy naturally contains small amounts of butyric acid, which supports colon cell energy and barrier strength. Good sources include:

◦Grass fed butter
◦Ghee
◦Aged cheeses like Parmesan
◦Whole milk, cream, or yogurt

Aim for 30 grams of fiber each day, but don’t rush the process. Your gut needs to be ready before you introduce larger or more complex sources. While dietary fiber is the primary raw material, the type, form, and timing of fiber introduction all matter. For your body to use dietary fiber properly, you need to heal your gut first.

Why You Can’t Just Add Fiber — The Terrain Has To Be Ready

Fiber is often treated as a one-size-fits-all solution for gut health, but its impact depends entirely on the state of your microbiome. In a balanced system, fiber feeds bacteria that convert it into butyrate and other protective compounds. But when the microbial terrain has been altered, the same fiber that should support healing can worsen symptoms instead.

• Polyunsaturated fats (PUFs) shift the microbial landscape — Linoleic acid (LA), the dominant PUF in vegetable oils like soybean, corn, safflower, sunflower, and canola oils, and a primary ingredient in ultraprocessed foods, is one of the biggest drivers of microbial disruption. These oils oxidize easily, generating reactive compounds that damage the cells lining your colon and promote low-grade inflammation.

• Fiber can backfire when the wrong microbes take over — When fiber enters a disrupted gut, its effects are unpredictable. Instead of being fermented into SCFAs, it may be broken down into gas, lactic acid, ethanol, or other irritants, provoking bloating, urgency, and discomfort — not because fiber is inherently problematic, but because opportunistic microbes are fermenting it.

• Oxygen levels rise when colon cells lose access to butyrate — As colonocytes metabolize butyrate, they help maintain a low-oxygen environment that favors beneficial anaerobic bacteria. When butyrate becomes scarce, colonocytes switch to glucose and lose this oxygen-lowering function.

Oxygen accumulates, making the environment more hospitable to inflammatory microbes that wouldn’t otherwise thrive. This shift reinforces the loss of butyrate producers and accelerates microbial imbalance.

• Removing LA sources is the first decisive step — Replace industrial seed oils with healthy, stable fats, such as butter, ghee, tallow, and coconut oil. These fats resist oxidation during digestion and do not contribute to the inflammatory shifts associated with industrial oils.

C15:0, a nutrient found in trace amounts in full-fat dairy, is especially beneficial at this stage. It has been shown to promote mitochondrial function, reduce inflammatory signaling, and support metabolic resilience.17 Adding these fats helps reestablish the conditions needed for microbial repair.

• Clear markers signal when the gut is ready for fermentable inputs — Stable bowel movements, reduced bloating and urgency, steadier energy, and improved tolerance to previously troublesome foods show that microbial balance is shifting. Better sleep, clearer skin, and more consistent appetite cues often accompany this transition and suggest stronger barrier integrity.

By setting the stage for butyrate production first, you establish the conditions needed to rebuild fermentation capacity in the next stage. For an in-depth understanding of this approach, read “Butyrate — The Metabolic Powerhouse Fueling the Gut and Beyond.”

More Strategies to Support Butyrate Production

In addition to dietary shifts, certain lifestyle habits can help stabilize your gut environment and enhance your body’s ability to generate butyrate consistently. Here are some of my recommendations:

• Prioritize consistent, quality sleep — Butyrate helps regulate circadian rhythm and sleep quality, but the relationship is bidirectional. Poor sleep alters microbial composition, while good sleep supports gut health.18

• Use movement strategically — Regular physical activity increases microbial diversity and supports SCFA production.19 Walking after meals also helps regulate blood sugar and improve motility.

• Manage stress consistently — Chronic stress disrupts gut permeability and shifts microbial balance in a way that lowers butyrate output.20 Breathing exercises, meditation, time in nature, and structured downtime help bring the system back to equilibrium.

• Reduce toxic exposures — These include electromagnetic fields (EMFs), endocrine-disrupting chemicals, antibiotics, and other gut-damaging compounds.

When Do You Need to Supplement?

Even with the right foods and a steady dietary routine, there are situations where your gut may still fall short of producing enough butyrate. In those cases, supplementation can act as a bridge, supporting your colon while you work on restoring microbial balance.21,22

• Long-term dysbiosis — If your gut has been disrupted for years, the microbes that convert fiber into butyrate may be missing or underactive. Short-term supplementation is especially useful when colonocytes are struggling and the system hasn’t yet regained its fermentation capacity.

• Underlying conditions that impair butyrate production — Autoimmunity, chronic inflammation, metabolic dysfunction, and neurological disorders often correlate with reduced levels of butyrate-producing microbes.23 In these situations, butyrate supplementation supports colonocyte energy, calms inflammation, and eases systemic stress while longer-term terrain repair unfolds.

• Exposure to acute stressor — Travel, antibiotics, infections, and periods of high stress can tilt the microbiome toward strains that don’t produce butyrate. Short-term supplementation helps stabilize the gut, protect the barrier, and prevent flare-ups during recovery.

However, it’s important to note that most butyrate supplements release too early in the digestive tract, dissolving in the small intestine before reaching the colon. To get its benefits, you need to choose a formula designed for targeted delivery throughout the entire colon.

Frequently Asked Questions (FAQs) About Butyrate

Q: What is butyrate?
A: Butyrate is a short-chain fatty acid your gut microbes produce when they break down fiber. It powers your colonocytes, strengthens your gut barrier, lowers inflammation, and supports everything from blood sugar regulation to mood stability. When your gut isn’t making enough, many systems in your body feel the effects.

Q: What foods should I eat first to support butyrate?
A: Start with simple, easy-to-digest carbohydrates like cooked and cooled rice and peeled and cooked root vegetables. These stabilize your system without overwhelming it. Once tolerated, you can expand to a variety of foods, including garlic, leeks, chicory root, berries, and soaked legumes.

Q: How much fiber should I be eating every day?
A: Aim for 30 grams per day, but don’t rush it. You need to match your fiber intake to your gut’s current capacity.

Q: What fats help with butyrate production?
A: Stable, saturated fats support a gut environment that favors butyrate-producing microbes. These include grass fed butter, ghee, tallow, and coconut oil. C15:0, a fatty acid found in full-fat dairy, is especially helpful. It supports mitochondrial health and reduces inflammatory signaling. Avoid seed oils like soybean, corn, and canola, which disrupt microbial balance and inflame the gut lining.

Q: When should I consider taking a butyrate supplement?
A: You may need to supplement if your gut has been chronically dysbiotic, if you’re managing a condition that lowers butyrate production, or if you’re recovering from antibiotics or infections. Butyrate supplements can help stabilize your gut and protect the colon while your microbiome recovers.

According to recent estimates, around 1 in 6 people in the United Kingdom (U.K.) have vitamin D levels that fall below the government’s set standards.1 When this becomes chronic, health problems eventually appear, such as respiratory tract infections that can lead to lengthy hospitalizations.2

Acute respiratory tract infection is characterized by symptoms such as fever, cough, sore throat, body aches, difficulty breathing, fatigue, and in severe cases, chest pain or shortness of breath.3 Left unaddressed, these infections contribute to significant global morbidity4 and can escalate into life-threatening complications like respiratory failure.5

To combat respiratory tract infections, U.K. researchers are now sounding the alarm, linking low serum vitamin D levels to a higher risk of these health problems. As noted in other published studies, adequate levels of vitamin D help maintain immune system homeostasis — strong enough to fight off infections but regulated enough to avoid inflammation.6 In the featured study below, they show just how much your vitamin D levels can influence your chances of being hospitalized.

Increased Vitamin D Intake Helps Protect Your Respiratory Health

In a 2026 study published in The American Journal of Clinical Nutrition, researchers performed an unmatched case-control study using data taken from the U.K. Biobank. A total of 36,258 participants were selected, which included different ethnic backgrounds — White, Asian, Black, and mixed ethnicities.

The overall goal of the study was to establish a link between serum vitamin D levels, 25-hydroxyvitamin D, the form measured in standard blood tests, and its effect on hospitalization rates of respiratory tract infections like pneumonia and bronchitis.7

• Demographics at risk — The researchers noted that middle- and older-aged adults are at a higher risk of these conditions.8 Lead researcher Abi Bournot, Ph.D., argues that supplementation can help:9

“Supplementation of the vitamin, especially in the winter months when our exposure to sunlight is limited, is an effective way of increasing vitamin D and reducing the risk of serious respiratory tract infections. This is particularly important for older people who are at higher risk of death from such infections, and ethnic minority communities in the U.K., who are at a higher risk of vitamin D deficiency.”

• The impact of vitamin D levels on hospitalization rates — The researchers took existing vitamin D levels and hospital admission records from the dataset and used different analytical models to determine the connection between the two.

Participants with serum vitamin D levels below 15 nanomoles per liter (nmol/L) had a 33% risk of hospitalization compared to adults with an average vitamin D level of 75 nmol/L or more. Note that this is the unit of measurement for U.K. In America, 75 nmol/L is equivalent to 30 nanograms per milliliter (ng/mL).

• A look at other vitamin D ranges — Findings show that vitamin D levels above 15 nmol/L (6 ng/mL) generally had lower hospitalization rates. For example, those who had an intermediate range (15 to 74 nmol/L; 6 to 29.6 ng/mL) “were not associated with a statistically significant increase in risk.” Moreover, every increase of 10 nmol/L (4 ng/mL) in serum vitamin D was linked to a generally significant reduction in hospitalizations.10

“Our findings of a significant association between increased vitamin D levels in our bodies and reduced hospital admission rates warrants further study, and points to the potential for vitamin D supplementation and consumption of vitamin D fortified foods to reduce the risk of hospitalization with respiratory infections in the future, and therefore mitigate pressures on the NHS [National Health Service],” The researchers noted.11

Daily Vitamin D Intake Shows a Noticeable Advantage Against Respiratory Infections

In a related study published in The Lancet Diabetes & Endocrinology, researchers performed a meta-analysis from 40 randomized controlled trials to determine the impact of vitamin D supplementation on lowering the risk of acute respiratory infection.12

The study population involved a total of 61,589 participants across a wide range of countries and health backgrounds. Children to older adults were included, both healthy individuals and those with chronic conditions. This mix gives you a realistic sense of how vitamin D levels impact public health.

• Key findings of the study — The researchers reported that daily dosing produced a statistically significant reduction in acute respiratory infection risk, with a 16% lower risk of developing a respiratory tract infection compared with those who took a placebo.

However, bolus dosing — giving vitamin D in large, intermittent doses — did not have this effect. Only daily intake produced an advantage.

• Certain subgroups improved more than others — The researchers reported that baseline vitamin D status, age, and dose size did not significantly modify the overall statistical outcome at the meta-analysis level, but the subgroup that showed clear significance was, again, the daily intake group. This shows that the frequency of intake plays an important role in determining the impact of vitamin D on your health.

Another point worth noting is how consistent the findings were across different populations in the daily dosing subgroup. Whether participants were young, older, living with chronic illness, or generally healthy, the protective effect remained statistically reliable inside the daily-dose category. That means your background health status does not prevent you from gaining protection by vitamin D. Again, the main factor depends on a steady intake to support your immune system.

• A look at the safety outcomes — Serious adverse events were almost identical between vitamin D and placebo with an odds ratio of 0.96, which means that there is no meaningful increase in safety concerns from supplementation. Thus, there are close to no downsides when boosting your vitamin D levels.

More Data Show the Effectiveness of Daily Vitamin D

In another meta-analysis published in Nutrition Journal, researchers reviewed 43 randomized controlled trials with a total of 49,320 participants. Their goal was to figure out which vitamin D strategies work best for preventing acute respiratory infections. Similar to the previous study above, this one also involved children, adults, and older adults, people in good health, and others living with chronic issues.13

• Daily dosing produced a measurable improvement — The study reported “significant preventive effects of vitamin D supplementation” for daily users. This means that integrating vitamin D optimization into your routine every day offers a noticeable advantage. Even short-duration trials produced positive results.

• Dosing outcomes — The research included a dose-response analysis, which estimates how much vitamin D produces the best outcomes across different environments. According to the authors, the optimal range sits between 400 and 1,200 International Units (IU) per day, and this held true in both seasonal categories they evaluated.

Higher or very infrequent doses did not outperform this modest daily range, meaning more is not better when it comes to oral vitamin D supplementation. Instead, sticking to a moderate, steady intake yields the most consistent return.

• Group-specific effects — Exploring group-specific effects revealed even more insights. For example, daily dosing helped people across a wide age range, but the greatest benefits showed up in groups exposed to seasonal shortages of sunlight and those living in regions with long winter cycles. These are demographics most likely to face prolonged vitamin D insufficiency.

• The downside of bolus dosing — Similar to the previous study, this one also investigated bolus dosing and found similar results. Across the selected dataset, irregular dosing frequencies consistently failed to show significant benefit.

Optimize Your Vitamin D Levels with These Practical Strategies

In addition to reducing your risk of respiratory infections, increasing your vitamin D levels also benefits your health in different ways. In previous articles, I’ve highlighted how vitamin D supports metabolic health by improving insulin resistance and lowers blood pressure. These benefits offer a compelling reason to optimize your vitamin D production regularly, ideally every day.

The studies above focused on supplements because they’re easier to standardize in research — but your body was designed to make its own vitamin D. Supplementation is only something to consider when blood tests make it clear that you’re falling short.

1. Make sunlight your main vitamin D source — Your skin produces vitamin D the moment sunlight hits it. To maximize vitamin D production, expose as much skin as practical — arms and legs at minimum, torso if privacy allows. More skin surface means more vitamin D synthesis in less time, reducing your UV exposure while achieving the same benefit.

Now, how do you know if you’ve produced enough vitamin D for the day? If you notice redness or burning, you’ve gone past your safe limit. When your skin tone looks unchanged, you’re still within a safe range. This built-in feedback mechanism accounts for the current season, your latitude, and your natural skin pigmentation. However, before heading out, it’s important to read the next point.

2. Clear vegetable oils from your diet before ramping up sun exposure — As mentioned earlier, sunlight is the ideal way to produce vitamin D. However, if your diet has included canola, soybean, sunflower, safflower, or other seed oils, the linoleic acid (LA) from them has already built up in your tissues.

When LA absorbs ultraviolet light, it oxidizes, drives inflammation, and damages DNA. It also increases your sunburn risk, especially during the midday window when the ultraviolet B rays required for vitamin D production are strongest. To protect yourself, start by lowering your LA intake below 5 grams per day, and swap seed oils for traditional animal fats like tallow, ghee, or grass fed butter. If you can get it below 2 grams per day, that’s even better.

To help you track your daily LA intake, sign up for the upcoming Mercola Health Coach app. It contains a feature called the Seed Oil Sleuth, which calculates the LA in your food down to a tenth of a gram. This makes it far easier to stay within a healthy range.

Note that your body needs about six months of avoidance from seed oils to start clearing LA from tissues. As LA levels fall, your skin becomes more resilient to sunlight, and your sunburn threshold rises. This also increases your ability to safely benefit from midday sunlight.

Here’s another helpful tip — take C15:0 (pentadecanoic acid), which is normally found in grass fed dairy. In a previous article, I went into detail into how it accelerates the removal of LA from tissues.

3. Choose vitamin D3, and pair it with magnesium and K2 — If you need to take a supplement, choose D3 — this is the same form your skin makes. Interestingly, taking D2 reduces the availability of usable D3, disrupting the balance you’re trying to restore. To make D3 work properly, support it with magnesium and vitamin K2. Magnesium activates vitamin D so your tissues can use it, and K2 ensures that calcium moves into your bones instead of settling in arteries or other soft tissues.

These nutrients operate as a team. Without magnesium and K2, your body struggles to activate vitamin D, forcing you to take higher doses just to achieve the same effect. That approach creates more problems than it solves, specifically vitamin D toxicity.

4. Test your vitamin D levels twice a year — Knowing your baseline is important. So, I recommend keeping your vitamin D level between 60 and 80 ng/mL. If your results fall short, refocus on lowering your LA intake and gradually increasing safe sun exposure. Done right, you won’t even have the need to spend on supplements. Regular testing also helps you adjust your approach over time, ensuring that your strategy matches your actual physiology, so you’re not guessing all the time.

Frequently Asked Questions (FAQs) About Vitamin D and Respiratory Tract Infections

Q: How does vitamin D help protect against respiratory infections?
A: Vitamin D helps keep your immune system balanced and strong enough to fight infections while preventing excessive inflammation. Research shows people with severely low vitamin D face a 33% higher risk of hospitalization for respiratory infections like pneumonia and bronchitis compared to those with optimal levels.

Q: Should I take vitamin D daily or in larger weekly doses?
A: Daily dosing is far more effective. Multiple studies found that daily supplementation reduced respiratory infection risk by about 16%, while weekly or monthly bolus doses provided no meaningful protection. If you’re currently taking a large weekly supplement, consider switching to smaller daily amounts.

Q: How much vitamin D should I take each day?
A: Research indicates the optimal supplemental range is between 400 and 1,200 IU per day, with higher doses showing no additional benefit. Aim to maintain blood levels between 60 and 80 ng/mL, using sunlight as your primary source whenever possible.

Q: What supplements should I take alongside vitamin D?
A: Choose the D3 form and pair it with magnesium and vitamin K2. Magnesium activates vitamin D so your body can use it, while K2 directs calcium into bones rather than arteries. Without these cofactors, you may need higher doses that increase toxicity risk.

Q: How quickly will I see benefits from improving my vitamin D levels?
A: Benefits appear within a few months. Studies lasting less than four months showed noticeable improvements in respiratory infection rates, and the protective effects were consistent across all age groups and health backgrounds.

Most people train muscles. Far fewer think about the tissue that holds everything together — your tendons, ligaments, and fascia. But if you’ve hit a strength plateau, feel like your grip gives out too soon or deal with chronic shoulder tightness, it’s not your muscles holding you back. It’s the scaffolding they pull against and how well your nervous system knows how to use it.

That’s where weighted dead hangs come in. Simple, short and brutally effective, this movement does more than build grip strength. It rewires how your body stabilizes itself under stress. And unlike conventional strength training, it targets the slowest-adapting tissue in your body, which most workouts ignore entirely.

This overlooked exercise is gaining new attention from researchers, trainers and elite athletes for its ability to improve posture, reduce pain and unlock lasting full-body strength. Grip experts and military strength coaches now use it as a key tool for building resilience from the hands up.

Dead Hangs Strengthen Tendons Without Heavy Workouts

You don’t need a gym or a barbell to start rebuilding the connective tissue that supports your shoulders, spine, and grip. A simple bodyweight dead hang — just holding onto a bar and letting your body stretch — is one of the most effective ways to reinforce the tendons and ligaments that protect your joints.
Over time, these low-tech, high-impact holds help your body remodel collagen, improve posture and prevent the injuries that come from weak stabilizers. And unlike intense weight training, you can do them daily without burning out.

• Bodyweight hangs trigger collagen remodeling without added weight — When you hang from a bar, your body senses the stretch and responds by strengthening the tissues under tension. This process, called mechanotransduction, helps your tendons grow thicker and more resilient. You don’t need added resistance to get this benefit — just consistent practice and good form.

• The real gains come from consistency, not intensity — A daily bodyweight hang of 30 to 60 seconds signals your body to start reinforcing connective tissue. Over time, this adds up. Your shoulders become more stable, your grip gets stronger and you move with better alignment. There’s no need to go to failure or chase exhaustion. Your goal is repeatable, high-quality reps that build strength gradually.

• Once you can hang for 60 to 90 seconds, you’ll have options — If and only if you’ve built that base, begin experimenting with added weight. Start slow with a 5- or 10-pound dumbbell clipped to a dip belt or tucked in a backpack. The goal isn’t to max out — it’s to apply just enough load to deepen the tendon response, without stressing your joints.

• Weighted hangs show what’s possible, but they’re not where you begin — A 20-second hang with 100 extra pounds triggers intense collagen remodeling, but that’s not a starting point — it’s a destination. If you’re not prepared, jumping to weighted hangs risks tendon injury and nerve strain. Always master bodyweight hangs first.

• You’re training the muscles that protect your joints, not just the ones you see — Even without weights, dead hangs activate deep stabilizer muscles in your shoulders, back, and spine. These are the support systems that keep your joints aligned, improve your posture and prevent chronic pain. Strong stabilizers don’t just help in workouts; they change how you move through daily life.

Thick Bars Supercharge the Results — and Protect Your Hands

Switching from a 1-inch to a 3-inch grip drastically increases the muscular demand on your hands, forearms and wrists. This happens because your fingers have to spread wider and recruit more motor units — the nerve-muscle pairs that control strength and endurance. The larger diameter also increases passive tension in your tendons, giving them a stronger adaptive signal.

• A thick bar changes how the weight feels and challenges your grip more — It’s not just about the size. Because your hand is farther from the center of the bar, the mechanical leverage changes. This increases the torque, meaning your grip has to work harder to stabilize the same weight. You feel it instantly in your forearms and finger joints, even though the plate weight hasn’t changed.

• Thicker bars reduce pain, which lets you hang heavier — The surface area on a 3-inch bar is wider, which spreads out pressure across your palms. That means less skin shear, fewer hot spots and less pain. For many people, pain — not strength — is the limiting factor in dead hangs. This subtle change often makes the difference between hitting a training plateau and breaking through it.

• You shouldn’t add weight right away — Again, start with just your body weight until you can hold a hang for at least one or two minutes with good form. From there, add weight in 10 to 15-pound increments. Rushing into 100-pound hangs isn’t just unwise — it increases your risk of bruising your abdominal soft tissue, especially around the belt. Always pad the belt and listen to your body.

• A little bit each day goes a long way — You don’t have to schedule an entire workout around this. The stimulus is so compact that you can layer it into your day with minimal effort. One hard hang in the morning, another in the evening — done consistently, this alone could restructure how your connective tissues hold up under load.

Grip Strength Starts with Tendon Density, Not Muscles

In the video above, personal trainer Michael Eckert broke down the often-overlooked foundation of grip strength: tendon density. While most people associate grip power with how strong their hand muscles are, Eckert emphasized that “the stronger and more dense your tendons are, the more load your muscles can put on those tendons to create force.”1

• Tendons limit how strong your grip gets, unless you train them directly — Eckert pointed out that your body naturally “caps” how much tension it allows muscles to generate if the tendons they attach to are too weak. That cap protects you from injury, but it also limits how much strength you build. “Your body recognizes when you have weak tendons,” he explained, which is why developing dense, resilient tendons is key to reaching your true potential.

• Training tendons is slow, but consistent loading works — Because tendons have limited blood flow, they adapt far more slowly than muscles. That’s why building grip strength isn’t about blasting your forearms once a week. Instead, Eckert stressed the importance of doing “a little bit every day” to get long-term results. He stated, “The process takes a long time to improve your grip strength. If you want long-term quality results, you’re going to have to spend a lot of time doing it.”

• Basic dead hangs still have a place in advanced training — Eckert described dead hangs as “more of a beginner exercise,” but also acknowledged that even elite climbers and athletes return to them regularly. When his hands are fatigued or he’s looking to maintain tendon health with low strain, dead hangs become his go-to. “You can always revert back to the basics to get the most out of your workout,” he said.

• Form matters more than complexity — Instead of chasing new gadgets or advanced techniques, Eckert encouraged sticking to foundational movements with great form. He builds much of his routine around simple isometrics — static holds — because they’re easy to repeat, scale and fit into a daily schedule without wrecking your hands. His message was simple: complexity doesn’t equal effectiveness.

• You don’t need a gym to train grip — Part of Eckert’s strategy is accessibility. He showed how he built his own spring-loaded hangboard using wood, resistance bands and minimal equipment. You can mimic the same effect with a piece of wood on a pull-up bar, a gallon of water or any weighted object that challenges your grip position. The goal isn’t perfect equipment — it’s regular practice.

No-Hangs Offer a Powerful Way to Load Tendons Directly

One of the standout techniques in the video was the “no-hang” — where you grip a ledge and simply pick up a weight with your fingers, without hanging fully from a bar. “All that is,” he explained, “is grabbing onto a ledge, picking up some amount of resistance, and holding it for a random amount of time or a set amount of time.” This method avoids the full strain of bodyweight but still delivers a powerful load to your tendons.

• These can be tailored to your strength level — No-hangs work whether you’re brand new or advanced. The amount of resistance and the ledge size are scaled to match your current capacity. He demonstrated options ranging from a 38-millimeter (mm) edge (easy) to a 15-mm edge (very hard), each with corresponding grip challenges. This helps you progress gradually and track improvements over time.

• Short sessions spread throughout the day are more effective than one big workout — Eckert explained that grip strength improves faster when you train it throughout the day rather than loading everything into a single session. “I feel a lot more benefit coming from that and the consistent effort than I do just dedicating like once a week to a grip strength workout,” he said. This matches what we know about tendon remodeling: consistent, low-volume loading wins.

• You need to train more than just squeezing — According to Eckert, grip strength isn’t just about crushing things with your whole hand. It involves all the different ways your wrist and fingers can move: pinching, pulling, flexing, twisting. “Anytime you’re moving, you’re pulling on a muscle,” he said, and to build full grip strength, you want to be training every action the hand can do.

• Movements like pronation and supination are often ignored, but essential — Two key movements Eckert demonstrated were pronation (rotating your hand palm-down) and supination (rotating palm-up). These motions use deep forearm muscles that stabilize your grip, especially under awkward or rotational loads. He showed how to train these using rubber bands or even a hammer to apply torque while your wrist fights back.

• Pinch and crimp strength are two separate skill sets — Eckert pointed out that even experienced athletes have hand asymmetries. His own weak spot was in the pointer finger and thumb, key for pinching and crimping. To fix this, he demonstrated an exercise where he grabs a 25-pound calibrated weight plate by the lip and performs micro reps, targeting his thumb and index finger with surgical precision. “This helps increase your overall hand strength and it’s an insane forearm flex,” he said.

Train Like a Soldier, Move Like an Athlete

In an interview between author and podcaster Tim Ferriss and strength expert Pavel Tsatsouline, he explains the principles behind his minimalist yet highly effective strength protocols, along with hands-on strategies to build grip and core strength without conventional weightlifting routines.2 Tsatsouline, credited with introducing kettlebell training to the U.S., is a former physical training instructor for the Soviet Special Forces and trains elite military units, athletes and civilians.

Tsatsouline emphasizes that most people overcomplicate training, relying on gimmicks and exhaustive routines instead of principle-based strength building. “The whole world of fitness is very confused,” he tells Ferriss. His approach strips everything down to the fundamentals: low-rep, high-frequency, nervous system-focused training that builds power without burnout.

• His strategies are built for environments where failure is not an option — Unlike athletes with the luxury of full-time recovery and carefully timed meals, soldiers must train for strength that holds up under extreme pressure. Tsatsouline says his methods are “antifragile” — they improve under stress, as effective programming must still work when nutrition, sleep, and comfort fall apart.

• You can instantly lift more weight using this one trick — Tsatsouline shares a technique for amplifying your strength during any lift: white-knuckle grip tension. When a lift gets difficult, crush the bar or weight in your hand as tightly as possible. This recruits more muscle fibers through a principle called irradiation, where muscle tension in one area spills over into neighboring muscles, increasing total force output. You’ll get several more reps out, he promises.

• Add your abs and glutes for even more power — Once you’ve mastered grip tension, Tsatsouline adds two more elements: tighten your abs as if someone’s about to punch you and contract your glutes like someone’s going to kick you. Doing all three at once — grip, glutes, abs — supercharges your whole body’s output.

• Train grip and core to improve everything else — If you don’t know what to focus on, Tsatsouline advises training your grip and your core. Why? Because both areas have an outsized impact on total body strength. Your grip has dense nerve connections to your brain, and when it’s engaged, your whole body follows. Your core amplifies your strength by increasing intra-abdominal pressure, like turning up the volume on your nervous system’s signals.

• Use ‘grease the groove’ to get stronger without fatiguing yourself — For grip strength, Tsatsouline recommends using a method he calls “grease the groove,” based on Soviet Olympic training protocols. Use a load or variation that feels challenging but controlled, and perform only half the number of reps you could do at maximum effort.

Then rest and repeat the same movement later — ideally every hour or two. The key is consistency without fatigue, which builds strength over time without risking burnout or injury.

Start with Bodyweight Hangs and Build from There

If you’re looking to fix weak grip, poor posture or nagging shoulder tightness, the best place to start is by strengthening the tendons and retraining your nervous system. That’s the real root of the problem — not muscle size, but fragile connective tissue and poor motor recruitment that limits how much force your body allows you to use. And the fastest way to reverse both is through dead hangs and neural priming techniques. But the way you do them matters.
You don’t need a gym or expensive equipment. Just something to hang from, consistent practice and a plan that’s smart enough to work with your body’s current strength. These are the steps I recommend if you want real results — stronger hands, better posture and pain-free movement — without injury or burnout. In the video above, calisthenics coach Pat Chadwick also walks you through how to master the dead hang and use four powerful variations to boost grip, posture and core strength, and ease shoulder pain.

1. Start with bodyweight-only hangs for 30 to 60 seconds per set — If you’re not comfortable holding your bodyweight yet, work up to it using resistance bands or partial hangs with your feet on the ground. The goal is to load your joints, not max out your muscles.

Two sets a day — morning and evening — is enough. And always stop before failure. Maintain tension in your shoulders by pulling them down slightly and engaging your lats. This primes your nervous system and protects your rotator cuffs.

2. Use a thicker grip to activate more nerves and protect your hands — Wrap a towel or foam pad around your pull-up bar. This makes your hand spread out more and activates more muscles without needing to add extra weight. A thick grip also spreads pressure across your palm and fingers, reducing the risk of blisters or nerve compression. This aligns with Tsatsouline’s principle of irradiation — activating one area (your grip) spills tension into nearby muscles, creating full-body strength.

3. Once you can hold 60 seconds, start adding weight, but keep reps short — Clip 5 to 10 pounds to a dip belt or use a backpack. Keep the load light and the form strict: shoulders engaged, core tight, steady breath. Aim for 20- to 30-second hangs. Adding glute and abdominal contraction during the hang, just as Tsatsouline recommends — will amplify your strength and protect your spine.

4. Use “grease the groove” to train smarter, not harder — You don’t have to train to exhaustion. Grease the groove means doing frequent submaximal sets throughout the day — just enough to signal adaptation, not enough to cause fatigue. For example, if you can hold a hang for 60 seconds, do sets of 20 to 30 seconds spaced out every hour or two. Over time, your grip, shoulders and nervous system will adapt, without needing to “recover” from a workout.

5. Train every movement your hand and wrist make, not just grip — Strong hands aren’t just about squeezing hard. You need wrist control in every direction. Use resistance bands, a bucket filled with dry rice or simple tools like hammers to train your hands and wrists in all directions. These targeted movements build balanced strength, lower your risk of injury and help you move more powerfully in sports, workouts or everyday tasks.

FAQs About Dead Hangs

Q: What are weighted dead hangs and how do they help?

A: Weighted dead hangs are short, high-tension holds where you hang from a bar, sometimes with added weight. They target tendons and ligaments, not just muscles, triggering collagen remodeling and strengthening the connective tissues that support your joints and posture.

Q: Do I need to add weight right away?

A: No. You should always start with bodyweight-only hangs until you can comfortably hold for 60 to 90 seconds. Starting with added weight too soon increases your risk of tendon strain or nerve compression. Build a strong foundation first.

Q: Why are dead hangs more effective than long workouts for tendon health?

A: Dead hangs apply targeted stress that your tendons recognize as a signal to rebuild. This process, called mechanotransduction, doesn’t require long workouts — just short, consistent effort that your body adapts to over time without burning out.

Q: What tools strengthen my grip and wrists at home?

A: Simple items like resistance bands, a bucket filled with dry rice or even a hammer can train different wrist and hand movements. These tools help strengthen your grip in all directions — pinch, twist, pull — creating resilience and preventing injury.

Q: How often should I do dead hangs or grip work?

A: Daily practice is ideal. Try a method like “grease the groove,” where you do short, submaximal sets throughout the day. Just one or two sets in the morning and evening creates lasting strength gains without fatigue or soreness.

If you’re among the tens of millions of Americans taking statin drugs, there’s a good chance you’ve experienced muscle pain, weakness, or fatigue. These are side effects that afflicts up to 29% of statin users. You may have been told to take CoQ10 to help with these symptoms — advice that sounds reasonable but, according to the published research, rarely works.

For years, I’ve been searching for a real solution to this problem, and I’ve found it. It’s called geranylgeraniol, or GG for short, and the science behind it explains not only why statin muscle problems occur but also why CoQ10 has failed so many people.

The $50 Billion Statin Problem Nobody Wants to Talk About

Statins are among the most prescribed drugs in the world. In the United States alone, approximately 40 million people take them. The pharmaceutical industry has built an empire around these cholesterol-lowering medications, generating tens of billions in revenue annually.

But there’s a dirty secret that undermines this entire enterprise: statin-associated muscle symptoms (SAMS) are so prevalent and debilitating that they represent the primary reason patients stop taking these drugs. When patients can’t tolerate the medication, they discontinue it — and the supposed cardiovascular “protection” vanishes along with the prescription.

The symptoms range from mild muscle aches and weakness to severe myopathy and, in rare cases, life-threatening rhabdomyolysis where muscle tissue breaks down and releases proteins into the bloodstream that can damage the kidneys.

For decades, the conventional solution has been CoQ10 supplementation. The reasoning seemed logical: statins inhibit the mevalonate pathway, which is the same pathway your body uses to produce CoQ10. Therefore, replacing the depleted CoQ10 should solve the problem. It was a tidy hypothesis — except it doesn’t actually work.

The CoQ10 Failure: What Multiple Meta-Analyses Reveal

A 2015 meta-analysis published in Mayo Clinic Proceedings1 evaluated randomized controlled trials investigating CoQ10 supplementation for statin-induced myopathy. The conclusion was clear: “The results of this meta-analysis of available randomized controlled trials do not suggest any significant benefit of CoQ10 supplementation in improving statin-induced myopathy.”

This wasn’t an isolated finding. A 2022 meta-analysis in the Irish Journal of Medical Science2 reached the same conclusion: “The outcomes of this meta-analysis of existing randomized controlled trials showed that supplementation with CoQ10 did not have any significant benefit in improving statin-induced myopathy.”

These aren’t fringe studies. These are comprehensive reviews of the best available evidence, and they consistently show that CoQ10 — the supplement doctors have been recommending for years — doesn’t actually solve the problem.

Why? Because CoQ10 isn’t the root cause of statin myopathy. It’s a downstream effect of a more fundamental disruption in cellular biochemistry.

The Mevalonate Pathway: Understanding Where the Real Problem Lies

To understand why GG works where CoQ10 fails, you need to understand the mevalonate pathway — the biochemical assembly line that statins disrupt.

Statins work by inhibiting an enzyme called HMG-CoA reductase, which sits at the very top of the mevalonate pathway. This enzyme is the rate-limiting step in cholesterol synthesis, which is why blocking it lowers cholesterol. But here’s what the statin manufacturers don’t emphasize: the mevalonate pathway doesn’t just make cholesterol. It produces numerous essential compounds your body needs to function.

When you block HMG-CoA reductase, you don’t just reduce cholesterol production. You reduce the production of everything downstream — including farnesyl pyrophosphate, geranylgeranyl pyrophosphate (GGPP), CoQ10, and vitamin K2.

Here’s where it gets critical: GGPP, the activated form of geranylgeraniol, is an obligatory substrate for the synthesis of CoQ10. In other words, your body cannot make CoQ10 without first having adequate GG. This means that trying to replace CoQ10 directly — while the GG deficiency persists — is like trying to fill a bathtub with the drain open.

But there’s an even more fundamental problem. GGPP is required for a process called protein prenylation, which is essential for muscle cell survival, function, and repair. When statin drugs deplete GG, they directly impair your muscles’ ability to maintain themselves at the cellular level.

The Science: GG Reverses Statin Myopathy at the Source

A landmark 2004 study published in Toxicology and Applied Pharmacology3 demonstrated something remarkable. Researchers found that statin-induced apoptosis (cell death) in muscle cells was completely prevented by mevalonate or geranylgeraniol. Even more striking, they found no correlation between ubiquinone (CoQ10) levels and apoptosis.

The conclusion was clear: statins cause muscle cell death by inhibiting protein geranylgeranylation, not by suppressing CoQ10 concentration. This finding turned the conventional CoQ10 hypothesis on its head and pointed directly to GG as the real solution.

Subsequent research has confirmed and expanded these findings. A 2018 study in Oxidative Medicine and Cellular Longevity4 found that GG “fully reverted the statin-mediated cell viability loss in proliferating myoblasts.” Water-soluble cholesterol, by contrast, only rescued toxicity caused by direct cholesterol depletion — proving that statin myotoxicity results from mevalonate pathway intermediate deficiency, not from lower cholesterol levels.

A 2019 in vivo study published in Translational Research5 took these findings from the laboratory into living animals. Researchers administered simvastatin to rats and found that it caused significant reduction in force production in fast-twitch muscle fibers — exactly what statin patients experience as muscle weakness and fatigue. When the rats were given GG along with the statin, this effect was completely eliminated.

Even more encouraging, the researchers found that GG improved muscle performance even in muscles not adversely affected by statins. And critically, neither control nor statin-treated animals given GG showed any adverse changes in cardiac function or blood vessel relaxation. GG appears to selectively protect and enhance skeletal muscle without negative cardiovascular consequences.

A 2023 Opinion Paper Calls for a Paradigm Shift

A November 2023 opinion paper published in Frontiers in Physiology6 synthesized the evidence and made the case explicitly. The authors noted that “myopathy is the most common side effect of statins, but it has not been addressed effectively.” They explained that while both CoQ10 and GG syntheses are reduced by statin use, “CoQ10 supplementation has not been shown to reverse SAMS.”

The paper emphasized that “GG is an obligatory substrate for CoQ10 synthesis, an endogenous nutrient critical for skeletal muscle protein synthesis.” Multiple studies, they noted, “showed GG supplementation is effective in reversing SAMS.”

This represents a fundamental shift in how we should approach statin side effects. Rather than trying to replace a downstream product (CoQ10) that the body can’t properly use anyway due to the underlying GG deficiency, we should replenish the upstream substrate (GG) that allows all the downstream processes — including CoQ10 production — to proceed normally.

What Is Geranylgeraniol and Where Does It Come From?

Geranylgeraniol is a 20-carbon isoprenoid alcohol that occurs naturally in the human body and in various plants. It’s a diterpene — a class of compounds that includes other biologically important molecules like retinol (vitamin A) and phytol (a component of chlorophyll).

In nature, GG is found in olive oil, sunflower oil, and annatto seeds. The annatto plant (Bixa orellana), native to South America, is a particularly rich source and is where most supplemental GG is extracted from.

When you consume GG, it enters the mevalonate pathway and is converted to its activated form, GGPP. From there, it can be used for protein prenylation — the process that’s essential for muscle cell function — and as a building block for CoQ10, vitamin K2 (MK-4), and other essential compounds.

Importantly, taking GG does not interfere with statins’ ability to lower cholesterol. The cholesterol synthesis branch of the mevalonate pathway uses farnesyl pyrophosphate, not geranylgeranyl pyrophosphate. This means you can support your muscle health with GG while maintaining whatever cholesterol-lowering effect your doctor is trying to achieve with the statin.

Practical Recommendations

Based on the available research, GG supplementation appears to be a safe and effective strategy for preventing or reversing statin-associated muscle symptoms. Here are some practical considerations:

• Dosing — Most commercial GG supplements provide 150 mg to 300 mg per softgel. The research suggests that daily supplementation at these doses can help replenish GG stores depleted by statin use.

• Form — Look for supplements containing “GG-Gold” or similar branded forms of trans-geranylgeraniol derived from annatto seeds. These are the most studied forms.

• Timing — GG can be taken with or without food. Some practitioners recommend taking it at a different time than your statin to ensure optimal absorption of both.

• Combination with CoQ10 — While CoQ10 alone has not been shown to reverse statin myopathy, there may be value in combining it with GG. Once GG replenishes the upstream pathway, CoQ10 supplementation might provide additional support. However, the priority should be GG.

• Safety — GG has an excellent safety profile. No adverse effects on cardiac function or blood vessels have been observed. That said, always consult with a healthcare provider familiar with your medical history before starting any new supplement.

The Bigger Picture: Why This Matters

The GG story illustrates a broader truth about modern medicine: when we don’t understand the root cause of a problem, our solutions often miss the mark. For years, millions of statin patients have been told to take CoQ10 for their muscle pain. Many dutifully bought the supplements, took them faithfully, and experienced little or no benefit.

The failure wasn’t their fault. They were given incomplete information based on an incomplete understanding of the biochemistry. Now that we know GG depletion — not CoQ10 depletion — is the primary driver of statin muscle problems, we can finally offer people a solution that actually works.

If you’re experiencing statin-associated muscle symptoms, talk to your healthcare provider about geranylgeraniol. The science is clear, the mechanism is understood, and the evidence supports its effectiveness. After decades of failed CoQ10 recommendations, it’s time for a real solution.

FAQ

Q: Why do doctors often recommend CoQ10 for statin muscle pain?
A: Statins block the mevalonate pathway, which contributes to CoQ10 production. Clinicians assumed CoQ10 replacement would ease muscle symptoms caused by statins. That hypothesis did not hold up under clinical testing.

Q: What causes statin-related muscle damage if not CoQ10 deficiency?
A: Evidence points to depletion of geranylgeraniol (GG), a key intermediate in the mevalonate pathway. GG supports protein prenylation, a process required for muscle cell survival, repair, and function. Statins reduce GG availability by blocking HMG-CoA reductase.

Q: Why does GG address the root problem better than CoQ10?
A: GG sits upstream in the mevalonate pathway. Without GG, the body cannot synthesize CoQ10 or maintain normal protein prenylation in muscle cells. Replacing CoQ10 alone does not correct this upstream deficiency.

Q: What does research show about GG and statin myopathy?
A: Cell and animal studies report that GG prevents statin-induced muscle cell death and fully reverses statin-related muscle weakness. A rat study found GG eliminated simvastatin-related loss of muscle force without harming heart or blood vessel function.

Q: What is the key takeaway for you if statins cause muscle pain?
A: Evidence suggests statin muscle symptoms stem from GG depletion rather than CoQ10 loss alone. GG supplementation targets the upstream biochemical disruption responsible for muscle dysfunction. Discuss this option with your health care provider before changes to supplements or medications.

Many Americans today are willing to spend money on a good night’s sleep. Case in point: In 2023, the U.S. home-bedding market reached $25.7 billion,1 a sign of just how important bedtime comfort has become, and pillows play a big role in it. They’re easy to replace, and with specialty and luxury options costing $30 to $300,2 it’s no surprise that people try different types to see what helps them rest better.

But even seemingly harmless habits can have unintended consequences. When something as simple as a pillow starts affecting the body in ways most people never consider, it’s worth paying attention — especially for older adults who are keeping an “eye” on their health.

A Closer Look at Glaucoma

Glaucoma, often called a “silent thief,” is the second leading cause of blindness worldwide, affecting about 80 million people and rising3 with aging populations. Most people do not notice early changes because glaucoma usually develops without pain or overtly visible symptoms.

• How glaucoma starts — The disease progresses when fluid pressure rises inside the eye — a condition called ocular hypertension — and gradually crushes the delicate fibers of the optic nerve. Peripheral vision declines first, followed by central vision as glaucoma advances.

• Groups who face higher risk — The risk rises for individuals over age 40, especially those with Black or Hispanic heritage, and with a family history of glaucoma or ocular hypertension, diabetes, high blood pressure, myopia, prolonged steroid use, previous eye injuries or surgeries, and conditions such as pigment dispersion syndrome.

• Available treatment options — Aside from relieving pressure in the eye, treatment options include prescription eyedrops or oral medications, laser procedures, surgical drainage techniques, and supportive nutritional approaches. Regular eye exams are also important, because optic nerve damage cannot be reversed.

Can Sleeping with Fewer Pillows Be Good for Your Eyes?

A 2024 observational study published in the British Journal of Ophthalmology4 examined how sleeping position affects intraocular pressure (IOP) and ocular blood flow in people with glaucoma.

Researchers followed 144 adults with various types of glaucoma and measured their intraocular pressure (IOP) every two hours over a 24-hour period while sitting, lying flat, and lying down with two pillows (also labeled as the high-pillow position) elevating the head by an angle between 20 and 35 degrees. The study evaluated changes in IOP, ocular perfusion pressure (OPP), which refers to the net blood pressure driving oxygen into the eye, and jugular vein blood flow to assess how pillow use influences nighttime eye health.5,6

• Stacked pillows significantly increased eye pressure — When participants slept with two pillows, average IOP rose from 16.62 millimeters of mercury (mmHg) to 17.42 mmHg, an increase of approximately 1.6 mmHg; 67% of patients experienced a measurable increase in pressure, and IOP fluctuations were greater during pillow use.

• Pillow use reduced blood flow to the eye — OPP dropped from 58.71 to 54.57 mmHg when participants used the high-pillow position. That means less fuel reaching the optic nerve precisely when nighttime repair should be happening.

Lower OPP indicates reduced delivery of oxygen and nutrients to eye tissues, which increases vulnerability to tissue damage from poor blood supply.

• Neck flexion from pillows impaired venous drainage — Imaging studies in 20 healthy volunteers showed that stacked pillows narrowed the jugular vein and altered blood flow dynamics. This suggests that neck bending compresses venous outflow pathways, thereby limiting drainage of aqueous humor — the clear fluid that nourishes the eye and maintains pressure balance — and venous blood from the eye, contributing to IOP elevation.

• Younger adults and primary open-angle glaucoma patients were most affected — Subgroup analysis revealed that younger participants and individuals with primary open-angle glaucoma experienced greater increases in IOP with pillow use. This indicates that certain patient populations may be more sensitive to postural changes during sleep.

• Sleep posture matters — For glaucoma patients, avoiding sleeping positions that flex the neck or compress the jugular veins may help reduce nighttime IOP spikes. While further research is needed, these findings suggest that modifying a simple nightly habit could support long-term eye health and serve as an easy, nondrug strategy for protecting the optic nerve.

• Findings are preliminary and require confirmation — As an observational study, causality cannot be completely established, and researchers recommend conducting more research on this topic.

“Traditional strategies of nocturnal IOP management are primarily limited to increasing the types and frequency of IOP-lowering medications or supplementary laser therapy. Given the well-documented influence of postural changes on IOP, positional modification emerges as a plausible strategy warranting further investigation,” the authors noted.7

The featured study shows that how you sleep matters — but additional research also suggests that how long you sleep, especially if you carry excess weight, may independently affect eye pressure.

Too Much Sleep or Extra Weight May Strain Your Eyes

A population-based study published in Medicine8 examined whether nightly sleep duration is associated with open-angle glaucoma (OAG) and whether body weight modifies this association. Researchers used data from Korea’s National Health and Nutrition Examination Survey (KNHANES) and looked at 9,410 adults aged 40 and older who completed health interviews, medical testing, and comprehensive eye examinations.

The subjects were grouped based on their sleep duration: less than five hours, five to six, six to seven, seven to eight, eight to nine, and nine or more hours. The researchers also diagnosed OAG using international criteria focused on optic-nerve structure and visual-field loss.

• Short and long sleep were tied to higher glaucoma prevalence — The data showed a U-shaped pattern, meaning risk is higher at both extremes and lower in the middle. In plain terms, people sleeping less than five hours had the highest prevalence, followed by those sleeping nine or more hours. Adults in the seven-to-nine-hour range had the lowest prevalence.

• Overweight adults faced the strongest association — Among participants with a body mass index (BMI) of 25 or higher, sleeping less than seven hours or nine or more hours significantly increased the odds of glaucoma compared to adults with a lower weight.

• Abdominal obesity followed the same U-shaped curve — In people with larger waistlines, glaucoma prevalence was highest among very short and very long sleepers, especially at nine or more hours. The pattern was not observed among participants without abdominal obesity, suggesting that central adiposity is a key amplifier of sleep-related eye risk.

• Melatonin disruption may be a key factor — The authors propose that abnormal sleep duration may reduce melatonin, a hormone that regulates circadian rhythms, protects retinal cells from oxidative stress, and has been shown to lower IOP. Reduced melatonin may impair optic nerve resilience, especially in metabolically vulnerable individuals.

• Long sleep may increase nighttime blood pressure drops — Extended sleep may worsen nocturnal hypotension, which has been linked to the progression of normal-tension glaucoma by reducing blood flow to the optic nerve during sleep.

• The results can be a wake-up call — Despite the study’s limitations, the authors acknowledged that self-awareness about your sleeping patterns may help mitigate your glaucoma risk. “These findings suggest that approaches specific to individual sleep patterns and body types may be helpful in the management of glaucoma,” they concluded.9

What You Should Know About Statins and Eye Health

Statins are widely prescribed for lowering cholesterol levels, and millions of adults take them daily to supposedly reduce cardiovascular risk. But emerging research suggests these medications have unintended effects on eye health, particularly when it comes to glaucoma.

• Statin use was linked to more glaucoma diagnoses — A 2024 study published in Ophthalmology Glaucoma analyzed health records from 79,742 adults age 40 and older with high cholesterol in the All of Us (AoU) Research Program. After accounting for age, sex, and medical factors, the researchers found that statin users had a 13% higher likelihood of having glaucoma than non-users.10

• The increased risk was most pronounced even when LDL cholesterol (“bad cholesterol”) was well-controlled — Statin users with optimal LDL levels (less than 100 milligrams per deciliter) had a 39% higher likelihood of glaucoma, while those with high LDL levels (160 to 189 mg/dL) had a 37% higher likelihood. This pattern suggests that the elevated glaucoma risk may stem from the statins themselves, not from poorly managed cholesterol.

• Age amplified the association — Adults aged 60 to 69 who used statins showed a 28% higher likelihood of glaucoma, indicating mid-to-late adulthood may be a particularly sensitive window for eye-related effects.

• What this may mean for patients — The findings suggest that statins, cholesterol levels, and age may interact in ways that influence glaucoma risk. While statins remain popular for managing cardiovascular health — a practice I don’t recommend due to its well-documented side effects — the study highlights the need for individualized monitoring, especially in older adults or those with additional glaucoma risk factors.

As concerns grow about medication-related eye effects, many people are exploring nondrug approaches to visual health, including relaxation-based methods and solutions that involve improving one’s nutrition.

The Bates Method for Better Eyesight Without Glasses

The Bates Method11 is one of the most enduring approaches to natural vision improvement. First introduced in 1919 by Dr. William H. Bates, an American ophthalmologist, the method was based on his belief that eye strain and not structural defects caused most vision problems.

Today, this method continues to attract interest from those exploring alternatives to glasses, especially among advocates of relaxation-based wellness. Many natural health teachers and vision coaches continue to adapt Bates’ ideas today. In fact, author Aldous Huxley famously credited the method with helping his vision.

• The method focuses on tension, not eye strength — Rather than treating blurry vision as a problem of weak muscles, the Bates Method encourages mental and physical relaxation to reduce chronic eye tension. Core practices aim to soften focus habits, restore natural eye movement, and build visual awareness without relying on corrective lenses.

• Palming is a foundational relaxation technique — One of the most well-known Bates practices, palming involves gently covering the closed eyes with the palms to block out light and encourage relaxation. Practitioners typically hold this position for a few minutes, allowing eye muscles and the nervous system to settle before returning to visual tasks.

• It’s often confused with vision therapy — The Bates Method emphasizes “eye exercises,” particularly eye movement and shifting focus, which superficially resemble techniques used in vision therapy. However, vision therapy is a clinically supervised, medically supervised approach used to treat conditions such as amblyopia (lazy eye) or convergence insufficiency.

• This method is still taught today through Bates Method International — Bates’ ideas carry on through organizations such as Bates Method International,12 which teaches relaxation-based techniques derived from his original work and from his book “The Bates Method for Better Eyesight Without Glasses.”

While controlled studies have not confirmed that the Bates Method can reverse myopia or astigmatism, many people report subjective improvements in visual comfort, reduced strain, and greater awareness of visual habits.

Using DMSO for Your Eyes

Dimethyl sulfoxide (DMSO) is an “umbrella remedy” with a unique affinity for the eyes. It has been used to treat a range of visual disorders — even cases of vision loss where conventional therapies have failed. DMSO’s potent anti-inflammatory effects make it useful for difficult eye conditions like iridocyclitis13 and uveitis,14 while also breaking up adhesions (synechia) that worsen these issues.

• It may reduce IOP and protect the optic nerve — Glaucoma involves progressive optic nerve degeneration, commonly linked to elevated IOP, impaired fluid drainage — including within the cornea15 — or elevated intracranial pressure.

• It may work when eyedrops or surgeries don’t — DMSO can stabilize proteins and solubilize misfolded ones, allowing it to reduce pathologic deposits such as floaters and cataracts.

• DMSO is supported by animal studies — In rabbits, a DMSO-brinzolamide gel lowered IOP without toxicity.16 Another study found that DMSO alone was effective in lowering pressure as well.17

In their Substack page, “The Forgotten Side of Medicine,” A Midwestern Doctor shares numerous testimonies from patients who’ve benefitted from using DMSO,18 many of whom had reported eyesight improvements after using this compound.

“I am two months into using 99.9% pharmaceutical-grade DMSO for loss of vision due to glaucoma … I haven’t been able to read letters in over two years with that eye. This week, I can now begin to see specific letters and numbers on my computer and the television screen,” one patient reported.19

Note: DMSO needs to be used responsibly. Only 99.9% pharmaceutical-grade DMSO should be used near the eyes and always diluted to safe concentrations. Always consult a knowledgeable practitioner before beginning use.

Other Ways to Protect Your Vision

While conventional treatments like glasses and eyedrops remain essential in many cases, there are also simple, research-backed strategies you can start using today to further support your eye health. In addition to rethinking your pillow choices, also consider the following strategies:

1. Cut out harmful seed oils from your diet — Seed oils — soybean, canola, safflower, sunflower — are loaded with linoleic acid (LA), a polyunsaturated fat (PUF) that, in excess, can impair mitochondrial energy production. Since the optic nerve is one of the most energy-demanding tissues in the body, mitochondrial dysfunction there may accelerate damage.

You can lower your exposure by replacing seed oils with more stable, nourishing fats such as beef tallow, grass fed butter, coconut oil, or ghee. For optimal health, aim to keep daily LA intake below 5 grams, ideally closer to 2 grams. To easily track your intake, sign up for the Mercola Health Coach app when it becomes available. It includes the Seed Oil Sleuth feature, which helps monitor your LA consumption to a tenth of a gram.

2. Get enough safe sunlight — Early-morning sunlight helps your mitochondria generate adenosine triphosphate (ATP), the fuel every cell in your body depends on. Try to expose your skin and eyes to gentle morning light each day. Hold off on midday sun until you’ve removed seed oils from your diet for at least six months.

3. Recover with rest and routine — Your eyes manage stress, including pressure changes, more effectively when your daily routines are steady. Maintaining a regular sleep and meal schedule helps maintain circadian rhythm, which affects IOP stability and nighttime repair processes in the optic nerve.

In the evening, dim the lights after sunset and limit screen time. Gentle lighting prompts your body to relax, boosts melatonin production, and promotes better sleep quality.

4. Explore vision-friendly herbs — Bilberry and ginkgo biloba20 have both shown promise in supporting circulation to the eye, strengthening capillaries, and fighting oxidative stress.

5. Quit smoking — Cigarette smoke creates high levels of oxidative stress and damages retinal blood vessels. Smoking significantly increases your risk of developing cataracts, macular degeneration, optic nerve damage, and even heart disease. Quitting is one of the best things you can do for your eyes and your entire body.

6. Stay active — Avoiding prolonged sitting and adding regular activity improves circulation, flexibility, and metabolic health. Brisk walking, gentle cycling, or swimming at least three times per week can help support optic-nerve resilience and reduce glaucoma-related risk factors.21

7. Boost your melatonin levels — In addition to regulating sleep, this hormone is also involved in regulating eye pressure. In a small 1988 study,22 doses as low as 0.2 mg of melatonin reduced eye pressure for up to four hours. While this remains early evidence, it aligns with the broader finding that healthy melatonin rhythms support nighttime eye repair.

If you’re considering supplementation, discuss low-dose melatonin use with your eye care provider, as most commercially available supplements are formulated at higher doses for sleep support rather than eye-specific outcomes.

8. Take lutein and zeaxanthin — These carotenoids concentrate in the retina and lens, filtering harmful blue light and protecting against oxidative stress. They’ve been shown to reduce the risk of cataracts, macular degeneration, and glaucoma.23 Leafy greens, bell peppers, and pastured egg yolks are great sources.

Frequently Asked Questions (FAQs) About Glaucoma Risk and Eye Health

Q: Why is glaucoma often called the “silent thief of sight”?
A: Glaucoma usually develops without pain or early visual symptoms. Optic nerve damage often progresses slowly, affecting peripheral vision first, which many people don’t notice until irreversible vision loss has already occurred.

Q: Can sleeping position really influence eye pressure?
A: Yes. A study in the British Journal of Ophthalmology found that sleeping with two pillows raised IOP and reduced blood flow to the eyes in people with glaucoma. Neck flexion may impair venous drainage, allowing pressure to build overnight.

Q: How does body weight affect glaucoma risk?
A: Excess body weight and abdominal obesity appear to amplify the effects of abnormal sleep on eye pressure and optic nerve stress. In overweight individuals, both short and long sleep durations were strongly linked to higher glaucoma prevalence.

Q: What role does melatonin play in eye pressure?
A: Melatonin helps regulate circadian rhythms and has been shown to lower IOP. Research indicates that small doses of melatonin can reduce eye pressure for several hours, while disrupted sleep or excessive light exposure may impair this protective effect.

Q: Can lifestyle changes really help protect vision?
A: Yes. Reducing seed oil intake, quitting smoking, getting regular exercise, supporting circadian rhythms with morning sunlight, and eating nutrient-dense foods rich in lutein all support optic nerve health and blood flow to the eyes.

Editor’s Note: This article is a reprint. It was originally published January 12, 2025.

I interviewed Dr. Alan Christianson, widely regarded as a premier expert on thyroid issues, and Ashley Armstrong, a regenerative farmer and founder of Angel Acres. Our discussion explored the intricate relationship between iodine intake and thyroid health, uncovering a paradox that has significant implications for your health.

To understand the current iodine dilemma, we need to rewind to the early 20th century. In the 1920s, iodine was added to table salt as a public health measure to prevent goiters — a swelling of the thyroid gland. Christianson explained that before iodine fortification, autoimmune thyroid disease was a rarity in medicine. However, within a decade of adding iodine to foods, rates among adult women skyrocketed, increasing up to 26-fold.

This historical intervention, intended to correct deficiencies, inadvertently set the stage for widespread thyroid issues. Armstrong emphasized the interconnectedness of iodine fortification across the food chain, including the mistaken belief that “if humans are deficient in iodine, then animals must be deficient too.”1 So, iodine was added not just to human salt but also to animal feed, resulting in significantly higher iodine levels in animal products and processed foods.

Iodine Overload Is a Modern Epidemic

Fast forward to today, and the narrative around iodine has taken a troubling turn. While there was once a legitimate concern about iodine deficiency, modern food production systems have transformed iodine into a stealthy toxin.

• Excess iodine is disrupting thyroid health — Armstrong highlighted, “The iodine content, which impacts thyroid health, has significantly increased in our food production system over the last 20 to 30 years.” This over-supplementation has led to an epidemic of thyroid dysfunction, including autoimmune thyroid disease, where your body attacks its own thyroid gland.

• Iodine accumulation is a growing crisis — Christianson added, “Iodine accumulation is a really big problem that our nation is facing. It’s one of those government interventions — oops — that have unintended consequences.”2 The excessive iodine intake is pervasive, stemming from various sources beyond fortified salt, making it difficult for individuals to control their iodine levels.

To learn more about the connection between iodine and thyroid health, read “Unmasking Thyroid Health via the Iodine Connection.”

5 Sources of Excess Iodine Beyond Table Salt

The underlying sources of modern iodine overload isn’t limited to fortified table salt. Christianson and Armstrong shed light on various sources contributing to excessive iodine intake:

1. Animal feed — Conventionally raised livestock are routinely supplemented with iodine, significantly increasing iodine levels in animal products. Armstrong emphasized that if animals are supplemented with iodine, the iodine levels in products like eggs increase five to 10-fold.

2. Dairy cleaning practices — The dairy industry commonly uses iodine-based disinfectants to clean teats and equipment. Although a hot water rinse helps mitigate iodine residues, the pervasive use of iodine teat dips introduces an additional, often unnoticed source of iodine into dairy products.

3. Processed foods — Iodine additives in processed grains and salt heavily fortify the food supply, making it challenging to control individual iodine intake if you consume processed foods. Christianson noted that many processed grains contain iodized dough conditioners. Even those that don’t explicitly list iodine often have significant levels when tested.

4. Personal care products — Iodine is prevalent in numerous personal care products, including some acne treatments, contributing to daily iodine exposure without consumers’ awareness. Armstrong pointed out, “Many common acne treatments contain a lot of iodine because of its antifungal and antimicrobial properties.”

5. Seafood and kelp supplements — While ocean-based seafood is a natural iodine source, fishmeal is also a common protein source for cattle feed, which increases iodine levels in eggs and dairy products.

These hidden sources of iodine make it increasingly difficult to regulate intake, contributing to widespread overexposure that negatively impacts your thyroid health.

What Are the Benefits and Risks of Thyroid Hormone Supplementation?

The conversation naturally transitioned to thyroid hormone supplementation, a common treatment for hypothyroidism. Christianson provided an important perspective that taking thyroid hormones from outside your body, even in bioidentical forms, isn’t the same as your body producing them naturally. As a result, this often leads to long-term complications.

• T4-only vs. combination therapies — Christianson distinguished between T4-only medications and combination therapies (T4 plus T3), noting that the latter often yield better patient outcomes. However, both forms present challenges, especially given the variability in iodine content of natural desiccated thyroid products.

• The impact of iodine levels on natural desiccated thyroid — Armstrong raised concerns about historical and modern practices, including the fact that in the early 1900s, cattle weren’t supplemented with iodine, so their thyroids had low levels.

• Regulatory concerns with NDT supplements — Today, livestock are overloaded with iodine, making natural desiccated thyroid supplements likely much higher in iodine than historical counterparts. Christianson explained the regulatory landscape, in that prescription forms of natural desiccated thyroid are standardized for iodine content, but over-the-counter versions often lack this quality control, leading to unpredictable iodine levels.

What’s the Connection Between Iodine and Breast Health?

Our discussion also touched upon the role of iodine in breast tissue health. Christianson elaborated on studies linking high iodine intake to increased breast cancer risk, particularly in populations with overexpressed sodium iodide symporters in breast tissue.

• Iodine overexpression and cellular damage — He explained that in pathologic breast tissue, the sodium iodide symporter is overexpressed, leading to heightened iodine uptake and cellular damage. This overexpression correlates with higher breast cancer rates, debunking earlier theories that iodine supplementation might be protective.

• Iodine supplementation is not a protective factor — Christianson clarified that while high-dose iodine temporarily reduces iodine uptake in fibroadenomatous breast disease, population studies indicate that higher iodine intake is associated with increased breast cancer risk. Thus, iodine is not a protective factor for breast tissue. He explains:
“In the case of breast cancers, there have been assays looking at Japanese women and contrasting their iodine excretion, their urinary iodine in groups with their overall breast cancer risk. And those in the highest quintiles and quartiles have proportionately higher risks for breast cancer. And there’s a linear relationship. So, the more they’re consuming, the greater their risks are.”

These findings debunk the myth that iodine protects breast health and emphasize the need to reevaluate iodine intake in the context of disease risk.

What’s the Link Between Thyroid Antibodies, Autoimmunity, and Epigenetics?

Our conversation also focused on the role of thyroid antibodies in autoimmune thyroid disease. Christianson emphasized that thyroid antibodies, such as antithyroid peroxidase and antithyroglobulin, are more predictive of thyroid symptoms and risks than T4 or thyroid-stimulating hormone (TSH) levels alone.

• Thyroid antibodies indicate autoimmunity — Elevated thyroid antibodies indicate an autoimmune response, which is the primary driver of thyroid dysfunction today.

• Epigenetics and generational iodine exposure — Epigenetics are also involved, as early iodine exposure affects thyroid health across generations. Armstrong noted, imagine being born into a womb with higher iodine levels, then supplementing with iodine throughout life and consuming a high-iodine diet. This exposure leads to accumulated iodine generation over generation.

• Genetic variations impact iodine metabolism — Christianson agreed, explaining that genetic variations significantly influence how individuals metabolize iodine. Those adapted to lower iodine environments are particularly susceptible to thyroid dysfunction when exposed to excess iodine. This epigenetic and genetic interplay complicates the iodine-thyroid relationship.

• Basal body temperature as a thyroid metric — The conversation also addressed basal body temperature, which is sometimes used as a metric for thyroid health, a practice championed by Dr. Broda Barnes. However, Christianson pointed out that the development of high-sensitive TSH assays and understanding of T3 metabolism shifted thyroid assessment away from basal body temperature.

While it’s true that many overtly hypothyroid individuals have lower body temperatures, the relationship isn’t as linear or reliable as once thought. Christianson noted:3

“Since Barnes’ time, we’ve learned that the thyroid basal body temperature connections are very real, but they’re not as linear, they’re not as tight as one might think. So many who are overtly hypothyroid will have a lower basal body temperature.

And during hyperthyroid storm, people often elicit a febrile response, but there’s not a linear increase in basal body temperature as one moves further into hyperthyroidism. That wasn’t understood during Barnes’ time.”

To dive deeper into the complexities of thyroid function and autoimmunity, read “Unraveling the Mysteries of Thyroid Health.”

How Does Cellular Energy Impact Thyroid Function?

Armstrong emphasized a holistic view of thyroid health, highlighting the multiple steps involved in cellular energy production:

• Thyroid hormone utilization involves four key steps — The process doesn’t stop at the thyroid gland. After T4 is produced, it needs to be transported, converted, and utilized at the cellular level.
“Metabolic health and cellular energy aren’t just about the thyroid gland. There are four different steps after the thyroid produces thyroid hormones — T4 is produced. Then there’s transporter proteins that have to take those thyroid hormones throughout the body.
That T4 must be converted to T3, cells must be able to accept that T3 and utilize it as the spark plug for energy production. So, there are a number of things that get in the way of cellular utilization of active thyroid hormone. Even if your thyroid is functioning well, using active thyroid hormone at various other parts of your body can be hindered.”

• Thyroid function varies at the cellular level — Christianson expanded on this, explaining that different body tissues have their own thyroid hormone ecosystem with different balances of thyronamines. This means that thyroid function at the cellular level is highly individualized and influenced by various factors like insulin levels, stress, and nutrient intake.

• Dietary factors impact thyroid hormone metabolism — Armstrong connected this to modern dietary practices, explaining that low-carb diets downregulate thyroid hormones, increasing reverse T3, and impairing cellular utilization of T3. High omega-6 polyunsaturated fatty acid (PUFA) consumption and stress further complicate this picture, reducing your body’s ability to use thyroid hormones effectively.

• Thyroid health is deeply interconnected with metabolic function — Thyroid hormone metabolism is influenced by many factors, including insulin levels, nutrient availability, and overall metabolic health. So, addressing thyroid issues requires a comprehensive approach that considers these interconnected systems.

• Photobiomodulation as a thyroid support tool — In a personal revelation, I also discussed my use of photobiomodulation (previously known as low-level laser therapy) to support thyroid health during my transition off thyroid medication. Christianson acknowledged the benefits, explaining that photobiomodulation helps improve antioxidant status in your thyroid, which is necessary for processing iodine without cellular damage.

Learn more about how photobiomodulation supports overall health and cellular function in “How Red Light Therapy Benefits Neuropathy, Myopathy and More.”

Managing Iodine Intake Is Key to Thyroid Health

The interplay between iodine intake and thyroid function is complex and often misunderstood. Excess iodine, a byproduct of historical fortification efforts and modern agricultural practices, poses a significant threat to thyroid health, contributing to autoimmune diseases and other dysfunctions.

• The role of a low-iodine reset in thyroid recovery — Christianson wrote “The Thyroid Reset Diet,” emphasizing a low-iodine regimen for one to three months to detoxify your body.

While Armstrong shared her concerns about maintaining nutritional balance during this phase, particularly regarding nutrients like choline, biotin, and calcium, Christianson suggested that selecting high-quality eggs and dairy that are low in iodine helps meet these nutritional needs without introducing excess iodine.

• Strategies to reduce iodine intake — Armstrong elaborated on practical strategies to reduce your iodine intake, stating:
“Don’t eat out as much, don’t eat food with an ingredient list, prioritize home-cooked meals … assess your supplements, stop iodine supplementation and evaluate your personal care products.”

By implementing strategic dietary changes, choosing high-quality food sources, and staying informed about iodine’s role in your body, you reclaim your ability to reach optimal thyroid health.

5 Practical Tips to Avoid Excess Iodine

Here are additional practical strategies to avoid excess iodine and protect your thyroid health:

1. Limit processed foods — Processed grains and packaged foods often contain high levels of iodine due to salt iodization and iodine-based additives. Prioritize whole, unprocessed foods to better control iodine intake. Further, a balanced diet rich in the right carbohydrates — and free of processed foods — supports cellular energy production, which is necessary for thyroid health.

Excess PUFA intake, including linoleic acid in seed oils, is a major culprit, as PUFAs interfere with your cell’s ability to use active thyroid hormone.

2. Choose high-quality dairy and eggs — Source dairy and eggs from farmers who do not supplement livestock with iodine or use iodine-based disinfectants. Pasture-raised and organic options are more likely to have lower iodine levels.

Armstrong noted that eggs from pasture-raised chickens without iodine in their diet have as low as 5 micrograms per egg, compared to eggs from chickens supplemented with iodine, which have up to 100 micrograms per egg.

3. Assess personal care products, supplements, and medications — Review all supplements and medications for iodine content. Avoid iodine-rich supplements unless medically necessary. Many personal care items, such as acne treatments, contain iodine. Opt for iodine-free alternatives to reduce iodine exposure.

4. Conduct an iodine inventory — Utilize tools like Christianson’s iodineinventory.com to track your iodine intake from all sources, including diet, supplements, and personal care products.

5. Explore additional therapies — Consider therapies like photobiomodulation to support thyroid health in conjunction with dietary adjustments.

Frequently Asked Questions (FAQs) About Iodine and Thyroid Health

Q: How does iodine affect thyroid health?
A: While iodine is essential for thyroid function, excessive intake leads to thyroid dysfunction, including autoimmune thyroid disease. Research shows that iodine fortification, initially meant to prevent goiters, has contributed to a rise in thyroid disorders.

Q: What are the hidden sources of excess iodine?
A: Beyond iodized salt, common sources include conventionally raised animal products, dairy (due to iodine-based disinfectants), processed foods, personal care products, and seafood or kelp supplements. These sources contribute to widespread iodine overexposure.

Q: Is there a link between iodine and breast cancer?
A: Studies suggest that high iodine intake may increase breast cancer risk, especially in individuals with certain genetic factors. Excess iodine leads to cellular damage in breast tissue.

Q: How do I lower my iodine intake?
A: Reduce or remove processed foods from your diet, choose dairy and eggs from farms that don’t supplement with iodine, check supplements and personal care products for iodine, and focus on whole, home-cooked meals.

After a workout, you probably already know to reach for protein. It’s one of the most common pieces of fitness advice, and for good reason. Protein provides the amino acids your muscles need to recover and grow, and getting it soon after training helps make the most of that recovery window. But there’s more to the story than just hitting a certain number of grams.

A recent randomized controlled trial conducted by researchers from the University of Illinois tested whether the fat packaged with your protein changes the muscle-building signal in the hours that follow exercise. Their findings revealed that not all protein-rich meals perform equally, even if the protein content is the same.1

How Fat Content Determines the Muscle-Building Response to Protein

The featured trial, published in The American Journal of Clinical Nutrition, enrolled 16 physically active adults who completed a resistance training session involving leg press and leg extension exercises. Immediately afterward, participants consumed one of three test meals, and researchers collected muscle and blood samples over the next five hours to measure the post-exercise muscle-building response.2

• Three meals, one key difference: fat content — Participants were randomly assigned to consume either a low-fat pork (LFP) meal, a high-fat pork (HFP) meal, or a carbohydrate-only (CHO) drink. All meals were precisely formulated. The LFP meal provided 20 grams of protein, 4.4 grams of fat, and 120 kilocalories.

The HFP meal also delivered 20 grams of protein, but with 20.6 grams of fat and 266 kilocalories. The CHO drink supplied 73.3 grams of carbohydrate and 266 kilocalories, with no protein or fat. The study design allowed for within-subject comparisons between pork meals and a parallel comparison to the carb-only condition.

• Lean pork produced the strongest muscle-building effect — Myofibrillar protein synthesis increased to 0.106% per hour after the low-fat pork meal, more than double the baseline rate of 0.047%. High-fat pork raised synthesis to 0.072% per hour, a modest increase that was significantly lower than the lean pork response.

The carbohydrate drink raised synthesis only slightly, from 0.040% to 0.056% per hour, with no significant effect. In head-to-head comparisons, lean pork outperformed both alternatives. Most notably, high-fat pork showed no significant difference from carbohydrate alone, meaning that the added protein failed to deliver a muscle-building benefit when it came packaged with a high-fat load.

• Slower amino acid delivery explains the outcome — Plasma levels of leucine, an amino acid essential for stimulating muscle protein synthesis, rose higher and peaked faster after the low-fat meal than after the high-fat meal. Essential amino acid concentrations followed the same pattern.

The researchers concluded that fat delayed or reduced the appearance of amino acids in the bloodstream, likely weakening the anabolic signal during the early window of recovery. Several mechanisms were proposed to explain this result:

“[T]he most straightforward answer is that differences in the lipid content of the pork conditions are known to result in slowed gastric emptying. The latter likely impacted the differential postprandial aminoacidemia observed and the subsequent enhancement of the anabolic properties of ingesting LFP compared with HFP,” the study authors reported.

“For example, past efforts have demonstrated that fast-digested proteins that contain a higher proportion of leucine are particularly effective at stimulating a postprandial rise in muscle protein synthesis rates. This concept has been coined the leucine trigger hypothesis and has largely only been pertinent when comparing isolated protein sources such as whey or casein.

Here, we demonstrated a more rapid and greater postprandial rise in plasma leucine concentrations in the LFP compared with the HFP condition … Hence, the enhanced anabolic effectiveness of the LFP condition may have simply been related to the leucine trigger, particularly because both LFP and HFP demonstrated a similar total net exposure to postprandial amino acids.”3

What Earlier Research Shows About Higher Protein and Muscle Growth

The featured study aligns with the findings of a 2020 review published in Nutrients, which examined current literature to determine how increasing protein intake affects body composition when combined with regular resistance training.4

• Higher protein intakes support increases in lean mass in trained individuals — Several trials included in the review reported that consuming protein well above the recommended daily amount (RDA) improved body composition during resistance training. In one 10-week study, resistance-trained men taking whey and casein gained more lean mass than those consuming carbohydrate alone.

Other trials found that intakes of 2 to 3 grams per kilogram per day (g/kg/day) during structured training programs supported either greater lean mass gains or more pronounced reductions in fat mass compared to lower-protein diets. These benefits appeared consistently in individuals who maintained regular resistance training.

• Not all studies found additional benefits, highlighting individual and training-related variables — While many trials showed improvements, others reported no difference between higher-protein and moderate-protein groups.

For example, some resistance-trained men consuming 2.6 to 3.3 g/kg/day showed no further advantage in lean mass or strength over individuals consuming roughly half that amount. These discrepancies suggest that training status, program design, baseline protein intake, and study duration influence outcomes.

• Pre-sleep protein meaningfully increases overnight muscle protein synthesis — One of the clearest findings in the review is that consuming casein before bed boosts overnight muscle protein synthesis. This response occurs in both younger and older adults and is even stronger when resistance exercise takes place in the evening. Casein is digested slowly, allowing a steady release of amino acids throughout the night, which supports muscle repair and adaptation.

• Long-term training programs combined with pre-sleep protein also improved muscle size and strength — In a 12-week evening resistance-training study, participants who consumed casein before bedtime increased quadriceps size and strength more than those receiving an isocaloric placebo.

Other long-term studies using morning or afternoon exercise showed mixed results, suggesting that timing relative to the training session influences how effectively pre-sleep protein supports adaptation.

• Higher protein intake does not increase fat mass — Across all trials included in the review, increasing daily protein intake did not lead to fat gain, even when total calories were higher. Some studies even reported reductions in fat mass in high-protein groups. The evidence consistently shows that protein overfeeding does not contribute to excess fat accumulation in trained individuals.

How Protein Source Shapes Recovery After Intense Training

Another study published in Nutrients in May 2025 provides additional evidence that animal protein offers a strong recovery advantage after intense exercise. The trial used a randomized, double-blind, placebo-controlled crossover design in military cadets completing the Army Combat Fitness Test, a demanding assessment that includes sprints, drag pulls, lifting tasks, and other high-output movements.5

• Researchers compared pork- and plant-based meals after maximal effort — Twenty-three men and women aged 18 to 40 completed clinical assessments, soreness ratings, dietary questionnaires, and blood and urine sampling at each visit.

Participants consumed either a pork- or plant-based MRE for three days after the fitness test, with meals similar in total daily protein but differing in amino acid density and creatine content. The crossover design allowed each participant to serve as their own control.

• Animal protein produced stronger recovery signals — Across the 72-hour recovery period, the pork-based meals led to lower muscle soreness in multiple thigh regions, a sharper reduction in cortisol at 48 and 72 hours, a higher testosterone-to-cortisol ratio within the pork condition, and reduced urinary urea nitrogen, indicating less protein breakdown.

These responses point to a more favorable recovery environment after consuming the animal-based meals, although testosterone itself did not differ between diets, and inflammatory markers showed mixed patterns rather than a uniform improvement.

• Amino acid density and creatine explained the advantage — The pork meals delivered substantially higher essential amino acids and nearly 10 times more creatine than the plant-based meals, as shown in the study’s nutrient tables.

The authors note that this richer nutrient profile may help explain improvements in soreness ratings, cortisol reduction, and nitrogen retention. The study did not test mechanisms directly but concludes that the plant-based meals would require targeted fortification with essential amino acids and creatine to match the recovery support seen with pork.

• Protein combining improves plant-based outcomes — Although the plant-based meals in this study contained less creatine and fewer essential amino acids, the authors emphasize that these limitations are correctable. They recommend fortifying plant-based MREs with additional essential amino acids and creatine to support post-exercise recovery on par with animal-based options.

This reflects the broader principle that protein quality depends on amino acid completeness and bioactive compounds. Combining plant sources like legumes and grains balances limiting amino acids and creates a more effective protein profile.

As long as you reach 2 to 3 grams of leucine per meal, plant-based meals can still promote muscle protein synthesis, provided total protein intake is high enough and timed to meet your recovery window.

These findings reinforce a consistent theme — after strenuous exercise, protein quality matters. Read more about the importance of protein quality in “Eating Animal Protein After Training Improves Recovery, According to Study.”

Setting the Right Daily Protein Target for Your Body

Daily protein needs depend on your ideal body weight, not the number you see on the scale alone. Ideal weight reflects what is appropriate for your height, age, and sex. Using current weight often inflates targets in people carrying excess body fat or sets them too low in those who are underweight, which leads to inaccurate and unhelpful protein goals.

• Start with a clear target based on ideal body weight — Most adults do well with about 0.8 grams of protein per pound of ideal body weight, or 1.76 grams per kilogram. This generally places protein at about 15% of daily calories. Roughly a third of that intake (about 5% of your daily protein) needs to come from collagen-rich sources such as bone broth, oxtail, shank, or other connective tissue cuts.

• Calculate your ideal weight before setting your intake — Use any reputable ideal body weight calculator and enter your height, age, and gender. Once you have that number, multiply it by 0.8 to find your daily protein goal. For example, if your ideal weight is 128 pounds, your daily target becomes about 102 grams. This method applies across body types and ages, including older adults, who often benefit from the higher end of the range.

• Spread protein evenly through the day — Dividing your intake across meals makes it easier to reach your target and improves how your body uses those amino acids. If you’re aiming for 100 grams per day, you can take in about 33 grams for each of your three meals.

A person with an ideal weight of 135 pounds would need about 108 grams daily, which breaks down to roughly 54 grams if eating twice a day. As a guide, one ounce of steak supplies about 7 grams of protein, so a 5-ounce serving gives you around 35 grams.

• Needs shift with age, activity, and health — Children require only 5 to 10 grams per meal, while young adults need about 20 grams. Most adults need at least 30 grams per meal to support muscle tissue. Older adults, athletes, and those recovering from illness often need more to overcome reduced anabolic sensitivity or increased training demands.

• Aim for balance rather than excess — Protein is essential, yet routinely going far above your requirement strains your organs and skews your amino acid balance, especially when collagen intake is low.6 Staying within your calculated range and using a mix of muscle and collagen-rich proteins supports strength, recovery, and long-term metabolic health.

For a deeper look at how to match your protein intake to your daily rhythm, read “When Is the Best Time to Eat Protein?”

What to Eat After Training for Muscle Recovery

Once you know your daily protein target, the next step is making sure each meal delivers enough leucine to trigger muscle repair. Aim for about 2 to 3 grams of leucine in your post-workout meal. Hitting this threshold ensures your protein actually stimulates recovery rather than simply adding to your daily total.

• Animal proteins are the most efficient way to meet this threshold — Grass fed beef, wild-caught fish, pastured eggs, and dairy all provide complete amino acid profiles and naturally high amounts of leucine in realistic serving sizes. Whey protein isolate is also highly concentrated, delivering close to 3 grams of leucine per scoop.

• Tempeh is a reliable plant-based option when portioned correctly — A 150-gram serving offers 28 to 30 grams of protein and a little over 2 grams of leucine, making it one of the few whole-food, plant-based choices that meet the post-workout recovery threshold without requiring additional powders or blends.

• Avoid unfermented soy products like tofu — While some sources include tofu as a plant-based protein option, unfermented soy has been linked to several health concerns. Tempeh remains the better choice, as fermentation helps break down many of soy’s harmful compounds. For more information on soy’s risks, read “Soybean Oil Linked to Genetic and Neurological Damage.”

• If you’re eating pork and poultry, choose pasture-raised varieties — The pork used in the studies above was part of a controlled research protocol, but for real-world use, sourcing matters. Conventional pork and chicken are often raised on feed high in polyunsaturated fats (PUFs), which alters the fat profile of the meat.

When possible, choose pasture-raised options. Organic, pasture-raised pork delivers high-quality protein and is one of the richest dietary sources of thiamine (vitamin B1), which supports mitochondrial energy production. Here’s a quick leucine breakdown for common post-workout protein choices:

Food (serving)
Protein (g)
Est. leucine (g)

Lean beef, cooked, 3 oz
22 to 26
2.3

Pork loin, cooked, 3 oz
24 to 26
2.1

Whey isolate, 25 to 30 g
23 to 27
2.5 to 3.0

Cottage cheese, 1 cup
25 to 28
2.0 to 2.5

Eggs, 2 large
12 to 14
1.0 to 1.2

Tempeh, 150 g
28 to 30
2.0 to 2.1

Milk, 16 oz
16
1.4 to 1.6

No matter which protein sources you rely on, make sure your meals still include high-quality fats (especially outside the post-training window), clean carbs, and colorful fruits and vegetables. When protein is integrated into a balanced plate, it supports daily recovery and long-term health without crowding out other essentials.

Animal Protein Remains Necessary Until Better Alternatives Exist

At this time, I firmly agree with the assertion that animal protein is required to optimize human biology. Yet after five decades of studying the issue, I’ve concluded that relying on animal sources is far from ideal.

That is why I am engaged in research to solve this dilemma — developing healthier, cost-effective alternatives from plants and microbial fermentation that can supply the dozen essential nutrients found only in animal foods, such as creatine, carnitine, choline, carnosine, vitamin B12, taurine, anserine, and others.

I am fully committed to this path, and once a practical replacement exists, I will no longer consume animal flesh. For now, there is no truly pragmatic alternative for most people, but creating one is my deepest commitment.

Frequently Asked Questions (FAQs) About Post-Workout Protein Intake

Q: Why does the amount of fat in my post-workout meal matter?
A: The featured study showed that meals with the same protein content produced very different muscle-building responses depending on how much fat they contained. The low-fat meal triggered a much stronger rise in muscle protein synthesis, while the high-fat meal produced a weaker signal that wasn’t any better than carbohydrates alone.

Fat appears to blunt this response because it slows gastric emptying and delays the rise in amino acids, especially leucine, during the early recovery window when your muscles are most responsive.

Q: If high-fat protein blunts muscle building, do I need to avoid fat entirely?
A: You don’t need to avoid fat altogether, but the findings suggest it’s ideal to keep it low in your immediate post-workout meal. Save richer fats for meals later in the day, when digestion speed doesn’t affect recovery as much.

Q: Can plant-based protein work as well as animal protein after training?
A: Yes, but it takes more planning. To match the recovery effect of animal protein, you need enough essential amino acids like leucine, and you may need to combine plant sources. Plant proteins also lack creatine, so adding creatine separately helps close the gap.

Q: How much protein do I need to eat each day?
A: Your target depends on your ideal body weight. Multiply your ideal weight (in pounds) by 0.8 to find your daily intake in grams. This gives you a more accurate number than using your current weight, especially if you’re overweight or underweight.

Q: How much leucine do I need after a workout?
A: Aim for 2 to 3 grams of leucine in your post-workout meal. This level reliably triggers muscle protein synthesis. Lean meats, pastured eggs, grass fed dairy, and whey protein make it easy to hit that threshold.

You sleep eight hours but wake up tired. You eat reasonably well but can’t lose the weight around your middle. Your doctor says your labs look fine, but something feels off — and it has for a while. Health doesn’t fail all at once. It erodes quietly, and that quiet erosion is exactly what the documentary Human OS: Health and Wellness in 2026 sets out to explain.

In the film, doctors and researchers describe a global shift away from symptom-driven medicine toward early detection, prevention, and personalization.1 They highlight the scale of metabolic dysfunction: current estimates place insulin resistance at up to 80% of the global population. Insulin resistance, meaning your cells stop responding normally to insulin, shows up as fatigue, weight gain around your midsection, unstable energy, poor sleep, and reduced exercise tolerance.

Left unaddressed, it sets the stage for diabetes, heart disease, cognitive decline, and shortened healthspan, often decades before a formal diagnosis appears. For decades, the standard medical playbook has been simple: wait until something breaks, then treat it. That’s not health care — it’s sick care, and it leaves millions of people stuck in a gray zone between “not yet diagnosed” and “not actually well.”

Chronic disease begins long before symptoms force attention — a point the cardiologists, functional medicine physicians, and performance specialists in the film return to repeatedly.

Subtle changes in sleep quality, stress tolerance, appetite, and recovery signal trouble early. Fasting insulin, heart rhythm monitoring, and basic imaging can identify risk in your 20s and 30s, not after a collapse or hospital admission. This approach reframes health as a system, not a series of isolated events, and places daily habits at the center of prevention.

What makes this shift different is practicality. Wearables, AI tools, and simple screening either reduce confusion or increase stress depending on how you use them. The documentary makes one point clear: data supports awareness, not obsession. Sleep consistency, hydration, movement, and recovery form the foundation, while personalized insights guide adjustments before damage accumulates. That sets the stage for a closer look at how predictive care works when applied to real lives, not abstract models.

From Sick Care to Self-Care: How Prevention Is Replacing Reaction

Instead of tracking disease after symptoms appear, the documentary explores how modern health care identifies risk earlier through sleep patterns, metabolic markers, movement capacity, and recovery habits.2 The central question stays practical: how do you stay functional and resilient long before a diagnosis forces change?

The discussions span young adults, working professionals, athletes, and people with no formal diagnosis who still experience fatigue, poor sleep, stress overload, and declining performance. The focus stays on people who appear healthy on the surface yet carry hidden risk beneath it.

• Sleep is the single most important habit you can fix — Tennis player Fares Al Janahi puts it plainly: “If you fix your sleep, everything will come with it.” There’s a direct mechanism behind this: inconsistent sleep elevates cortisol, your primary stress hormone, which raises blood sugar, increases fat storage around your midsection, and blunts your response to insulin. Fix the timing, and that entire cascade quiets down.

• Most people don’t get screened until something goes wrong — That’s backwards. The cardiologists in this documentary explain that simple health tests like fasting insulin, ECG monitoring, and basic cardiac imaging catch problems decades before a collapse or a hospital visit.
They describe active, apparently healthy people walking around with conditions like atrial fibrillation — an irregular heart rhythm that raises stroke risk — or structural heart issues, such as an enlarged heart chamber, that nobody thought to look for. A short, targeted screening in your 20s or 30s costs almost nothing compared to what happens when you wait.

• Wearables are useful until they aren’t — Athletes and clinicians in the film agree that tracking sleep, stress, and recovery gives you real insight — but only when you treat it as a short-term feedback tool. The moment you start obsessing over every score or letting a fitness tracker tell you how to feel about your day, the data works against you. Use it to learn patterns. Then trust what your body is already telling you.

• Stop chasing intensity — The documentary makes this point repeatedly: extremes don’t last. Overtraining breaks you down. Inactivity lets you decay. What actually protects long-term function is moderate, repeatable movement you sustain without burnout. Do the basics, like walking, well. Do them often. That’s the whole strategy.

• Insulin resistance is not a diagnosis you wait for — It’s a warning signal your body sends early — through fatigue, belly fat, unstable energy, and poor sleep — long before diabetes, heart disease, or cognitive decline show up on a chart.

The physicians in this documentary are clear: once you identify insulin resistance, daily walking, strength training, better sleep, and stress reduction reverse the trajectory by restoring insulin sensitivity — your cells’ ability to respond to insulin efficiently, which is the opposite of insulin resistance. This is actionable information, not a life sentence.

Recovery, Hydration, and the System That Holds It All Together

Recovery starts the moment you finish moving, not the moment something hurts. Physiotherapist Marcela Henao and the performance experts in the film stress that hydration, nutrition, and rest function as daily repair tools for your joints, muscles, and nervous system. If you wait for pain to tell you it’s time to recover, you’ve already fallen behind.

• You’re losing water right now. Not just when you sweat — Thinking, breathing, basic metabolic function — all of it depletes your reserves. The experts in this film emphasize hydrating before exertion, not after breakdown.
Nutritionist Lina Shibib and others describe adding Himalayan pink salt to water for natural electrolyte support and getting water through whole fruits and vegetables, not just drinking more glasses. To stay well hydrated, let your thirst be your guide and aim for clear, pale-yellow urine throughout the day.
• Your health doesn’t exist in isolation — Family, workplace culture, coaches, health care practitioners — they all shape your outcomes. As noted in the documentary, when one person in the system breaks down, everyone around them absorbs the cost. Your daily habits protect more than just you. They protect the people who depend on you.
• Chronic disease doesn’t appear overnight — It builds through years of ignored signals — poor sleep, unmanaged stress, skipped recovery, dehydration. But the reverse is also true. Small, consistent actions compound over time. You don’t need a dramatic intervention. You need repetition.
• The goal is not to live longer. It’s to live better — Lifespan means nothing without daily function, mental clarity, and physical energy. The real target is healthspan — staying capable, adaptable, and resilient for decades, not just adding years to a calendar.
• Fear doesn’t drive lasting change. Understanding does — The documentary closes exactly where it should: on fundamentals. Sleep at consistent times. Move daily. Hydrate. Recover. Screen early. Complexity is a distraction. The basics, done well and done often, deliver the largest return on your health.

Build Health Before Symptoms Force Action

This approach speaks to anyone who feels mostly fine yet senses something underneath is drifting off course. The objective stays clear: correct the upstream breakdown that drives fatigue, poor sleep, metabolic strain, and long-term disease risk. Every step below targets causes rather than surface markers, so progress builds steadily instead of reacting under pressure.

1. Make sleep timing the nonnegotiable foundation — Going to bed and waking up within a 30-minute window every day — meaning if you typically sleep at 10:30 p.m., you stay between 10:15 and 10:45 — stabilizes appetite signals, stress hormones, and daily energy. On weekends, resist the urge to shift by more than an hour. That consistency matters more than total hours. Once timing stays steady, other habits fall into place with far less effort.

2. Look for early warning signs instead of waiting for labels — Action begins long before pain or dramatic lab results appear. Tracking early markers — fasting insulin, HOMA-IR (a simple but powerful way to gauge how efficiently your body is responding to insulin), exercise tolerance, recovery speed, daily energy — reveals risk years ahead of diagnosis. Stubborn fatigue, belly weight, or declining stamina signals the moment to intervene, while change still carries momentum.

3. Keep movement regular and remove extremes — Daily walking and consistent strength training twice a week support insulin sensitivity, circulation, and mental clarity. Excessive exercise intensity drains your system and blunts progress. Persistent soreness, flat energy, or loss of motivation point to overload and greater need for recovery.

4. Remove seed oils from your diet — Linoleic acid (LA) from industrially processed seed oils — soybean, canola, corn, sunflower, safflower — accumulates in your tissues and drives chronic inflammation at the cellular level. It disrupts mitochondrial function — your mitochondria are the structures inside each cell that produce energy — worsens insulin resistance, and amplifies the metabolic damage that the documentary’s experts are warning you about.
Replacing these oils with stable fats like grass fed butter, ghee, and tallow reduces oxidative stress — the cellular equivalent of rust building up inside your engine — and supports the recovery and energy production your body depends on daily.

5. Support recovery and hydration every single day — Hydration and rest function as daily repair tools, not afterthoughts. Fluid intake matters before stress builds, not only after exertion. Consistent recovery prevents small stressors from accumulating into chronic breakdown, keeping tissues resilient and energy steady.

FAQs About Predictive Health Care

Q: What is “predictive and preventive” health care?
A: Predictive and preventive care shifts the focus from treating disease after diagnosis to identifying risk early and correcting it before damage accumulates. Instead of waiting for diabetes, heart disease, or cognitive decline, you track early signals like fasting insulin, HOMA-IR, sleep quality, and recovery patterns. The goal is to extend your healthspan — the years you feel strong and capable — not just your lifespan.

Q: Why is insulin resistance such a big concern?
A: Insulin resistance means your cells stop responding efficiently to insulin, the hormone that helps move sugar from your blood into your cells for energy. Early signs include fatigue, belly fat, unstable energy, cravings, and poor sleep. Left unaddressed, it increases your risk for Type 2 diabetes, heart disease, and cognitive decline. The good news is that consistent sleep, strength training, daily walking, and removing inflammatory seed oils directly improve insulin sensitivity.

Q: Are wearables and health trackers necessary?
A: They’re tools, not requirements. Short-term use helps you see patterns in sleep, stress, and recovery. Problems arise when you obsess over daily scores or let the device dictate how you feel. Use technology to learn about your body, then step back once you understand your rhythms. Awareness supports progress. Obsession disrupts it.

Q: Why does sleep matter more than diet or exercise?
A: Sleep regulates your metabolism, appetite hormones, stress response, and tissue repair. When sleep timing is consistent, your body stabilizes energy production and recovery. When it’s irregular, cravings increase, stress hormones rise, and metabolic dysfunction accelerates. Fixing sleep first makes every other habit easier and more effective.

Q: What’s the simplest place to start today?
A: Start with three fundamentals: consistent sleep timing, daily walking plus strength training twice weekly, and removing seed oils from your diet. Add proper hydration and regular screening like HOMA-IR. These steps address root causes — metabolic dysfunction, inflammation, and poor recovery — instead of chasing symptoms after they appear.
