Mark Hyman, M.D.

This morning, I had the pleasure of sitting down for an interview with @vickynguyentv on the @todayshow to discuss sugar becoming the next cigarette. We dived into the problem of high sugar consumption in the United States and how front-of-package labeling on packaged foods is a crucial first step towards a healthier society because education and awareness alone will only get us so far. FDA leadership ensuring labeling of high contents of sugar in packaged foods could increase awareness and reduce the negative impacts of sugar and help millions live healthier longer lives. This change would help us make more informed choices about our food and our health. We believe it is our right, and every American’s right, to have clear and visible information about the sugar content of the foods we are eating in order to make those decisions. To drive even more significant change in the way most Americans eat, a change that will lead to a healthier population, we must also incentivize the production and widespread distribution of healthier alternatives.

This is not just another announcement. Over the past few months, you’ve heard me talk about @functionhealth. This isn’t merely about new investors; it’s a signal from some of the world’s top institutions that empowering you to take control of your health outside the doctor’s office is critical. We’ve secured a $53M investment led by top investor @a16z Bio + Health. Early cancer detection is critical. Getting ahead of heart disease is critical. Understanding your hormones is critical. This investment ensures we can scale this revolutionary approach to reach billions of people. We've already seen countless stories of how Function Health has saved and transformed lives. Thanks to @CNBC Squawk Box for having me on the show this morning. A 44-year-old father of two discovered prostate cancer in stage one. A 51-year-old mother of four discovered ovarian cancer just in time before she was symptomatic. A 35-year-old fit man revealed a critical heart disease risk that typical physicals never caught. Over 60% of our members have a nutrient deficiency. Over 30% of our members are showing autoimmunity signals. This is about people’s lives. And in each case, Function was there to help them take control. We’ve designed Function to be the easiest and fastest way to take charge of your health, starting with 100+ lab tests that provide an extremely comprehensive picture of what’s actually happening inside your body. My career, beyond being a practicing physician, has been dedicated to educating people like you about your health. This is the next level, beyond just writing books. I’m tirelessly working to ensure millions have access to the same high-level healthcare that has been available to wealthy people with concierge doctors—and then going far beyond that. This is just the beginning. We built Function for you. It’s time you own your health.

Are you dehydrated? Most people think drinking water is the answer, but without electrolytes, much of that water never reaches your cells—where it’s truly needed for energy, focus, and overall health. Studies show that even mild dehydration can impact your memory, concentration, and emotional stability. Try my favorite electrolyte supplement, LyteShow (yellow label), or add a pinch of Himalayan salt and a squeeze of lemon to your water first thing in the morning. You’re most dehydrated after sleep, so “break the fast” with 500–1000 ml of lukewarm water, half a teaspoon of salt, and lemon juice. Why? Sleep is the longest period you go without drinking, so hydrating upon waking helps flush out toxins and rehydrate every cell. (Avoid table salt for best results.)

The truth about Ozempic! 📣 When you lose weight by any means, you reduce your risk of every chronic disease—from heart disease to diabetes, cancer, and dementia. It’s not the drug, it’s the weight loss. The data is clear. Losing weight through diet has more benefits across key biomarkers, like reducing inflammation, than weight loss drugs ever could. These drugs come with a laundry list of side effects. As the New England Journal of Medicine once joked: ‘Use new drugs as soon as they come out—before the side effects develop.’ We’re seeing that play out now. Half the people who start these drugs quit within a year, either due to side effects or cost. And if we keep relying on them, it’s going to bankrupt our healthcare system, costing us trillions. These drugs are a tool, but they’re not the answer. We need to fix our food and healthcare systems, support regenerative agriculture, and implement policies that make healthy eating accessible to everyone.

The next frontier in medicine is addressing the why behind chronic conditions, not just the what. Drop a YES below if you agree. These are symptoms of deeper imbalances in the body. Depression is often linked to inflammation, gut microbiome dysfunction, hormonal imbalances, or nutrient deficiencies (like omega-3s or B vitamins). While heart disease is driven by insulin resistance, poor diet, and chronic inflammation. We have to come to terms with the fact that there’s no easy fix. Medications can be life-saving tools, but they’re not the solution to the root causes of these conditions. America’s chronic disease epidemic won’t be solved in a pill bottle—it requires systemic change, starting with how we grow, produce, and consume food. The answer is already within our grasp; we just need to shift our focus.

Ultra-processed food is the # 1 killer in the world, responsible for over 11 million deaths annually. It’s not just a health crisis—it’s an economic one, costing Americans trillions in healthcare while our tax dollars fund the very foods driving disease. Last night on Cuomo, I broke down why this system is broken—and how we can fix it. From field to fork, we have the power to reclaim our health and transform our future. It’s time to confront the food industry and demand better. Let’s put health back on the menu.

Vitamin D might be the answer you need. New research reveals that vitamin D supplementation—at an average dose of 3,320 IU per day—may offer substantial cardiometabolic benefits! This extensive meta-study, analyzing 99 global trials, found that regular vitamin D intake is linked to reductions in blood pressure, cholesterol, fasting glucose, insulin, and HbA1C levels. Notably, those with lower initial vitamin D levels, people aged 50+, and those with a BMI under 30 experienced the greatest benefits. This study underscores that personalized vitamin D strategies could be key to heart and metabolic health.

Overeating isn’t about willpower—it’s about biology. Leptin, a hormone produced by fat cells, signals fullness to the brain. When leptin is out of balance and leptin resistance develops, it sends false hunger signals, leading to overeating and slow metabolism. Testing leptin levels provides insight into this imbalance. To gauge the broader cardiovascular and metabolic risks linked to leptin resistance, combine leptin testing with: -Insulin -High-Sensitivity C-Reactive Protein (hs-CRP) -Apolipoprotein B (ApoB) -Triglycerides -LDL Cholesterol -HDL Cholesterol -LDL Small -Hemoglobin A1c (HbA1c) Citation: Vilariño-García T, Polonio-González ML, Pérez-Pérez A, et al. Role of Leptin in obesity, cardiovascular disease, and type 2 diabetes. Int J Mol Sci. 2024;25(4):2338. doi:10.3390/ijms25042338

Our brains are on overload. Bombarded by endless notifications, doomscrolling, and heated debates—especially with politics dominating social media. This constant stimulation floods your system with stress hormones like cortisol, over-activating your amygdala (the brain’s fear center) and leaving you feeling anxious, irritable, and exhausted. Research shows that chronic exposure to this kind of stress impairs focus, disrupts sleep, and even weakens your immune system. Step away. Let your brain reset. Take a walk in nature, practice breathwork to calm your nervous system, or simply embrace moments of boredom—where creativity and problem-solving thrive. Disconnecting from the noise isn’t just a break; it’s essential for your mental and physical health.

You have more control over your fertility than you might think. Support fertility health by taking action: -Quit smoking -Avoid excessive alcohol consumption -Maintain a healthy weight -Reduce stress -Balance hormones For deeper insights, test the biomarkers that impact your fertility. These biomarkers can often go unchecked until issues arise, but testing them before trying to conceive allows you to catch potential problems early. You deserve to know your fertility status. Ask your doctor for these tests, or access them all through Function.
