Dr. Mark Hyman

Welcome to The Dr. Hyman Show, the podcast helping you take ownership of your health and reimagine what’s possible. Hosted by Dr. Mark Hyman—physician, bestselling author, and pioneer in functional medicine—this show explores the most pressing issues of our time: chronic disease, nutrition, mental health, food policy, prevention, and longevity.

In a world where our food system fuels disease and conventional healthcare often overlooks root causes, Dr. Hyman delivers evidence-based insights and expert conversations that empower you to become the CEO of your own health.

The Dr. Hyman Show goes beyond the headlines to envision a future where our food and healthcare systems support vitality, reduce chronic disease, and protect the environment. Whether you’re looking for actionable protocols, deeper understanding, or meaningful conversations at the intersection of health, food, and policy, this podcast is your trusted guide.

Tune in, take the lead, and transform your health one episode at a time.

The Doctor's Farmacy with Mark Hyman, M.D.

Chronic illness rarely fits neatly into a single diagnosis. Symptoms can span multiple systems, leaving people profoundly unwell even when standard testing appears normal. I understand this experience from the inside out because I’ve lived it myself.

Today, I sit down with Dr. Neil Nathan, a leading expert in complex chronic illness and author of Toxic, now in its second edition. We explore why these conditions are so often misunderstood and how identifying what is driving them can create a path toward recovery.

We discuss:

 Why mold toxicity, Lyme disease, and long COVID can be so difficult to diagnose

 How to identify the root cause instead of chasing downstream symptoms

 What the Cell Danger Response is and why the body can remain stuck in survival mode

 Why some people suddenly become sensitive to foods, chemicals, medications, light, and sound

 Why the right treatment can make symptoms worse when introduced at the wrong time

I’ve been sick enough to know how quickly chronic illness can narrow your world—and how discouraging it is when no one can explain why. But I’m also living proof that the body can recover. The answer is not always more treatment. Often, it begins with finding the root cause, respecting what the body can tolerate, and addressing each layer in the right order.

The Hidden Cause of Your Chronic Illness (It's Not What You Think) | Dr. Neil Nathan

Brain fog isn’t just a normal part of getting older—and it may not be a brain problem at all. If you struggle to focus, lose your train of thought, forget why you walked into a room, or feel mentally exhausted after eating, your body may be trying to tell you something.

Here’s what I discuss in today’s episode:

 The five foods I most commonly see contributing to brain fog—and why some seemingly “healthy” choices may be working against you

 The surprising connection between your gut and your ability to think, focus, and remember

 Why certain foods can affect your brain even when you don’t have obvious digestive symptoms

Brain fog is a messenger, not the root problem. When you start looking at what’s happening throughout your body—especially your gut, blood sugar, inflammation, and microbiome—you can begin uncovering what’s getting in the way of a clearer, healthier brain.

5 Foods That Are Making Your Brain Fog Worse

This week, I’m the one answering the questions in a deeply personal conversation about my health journey. I speak openly about some of the hardest parts of that journey, the treatments I’ve tried, the beliefs I’ve reconsidered, and what a lifetime devoted to health has taught me about what matters most.

Here’s some of what I share:

 How becoming the patient changed the way I practice medicine

 How nearly dying changed what longevity means to me and what I believe a healthy life is actually for

 Which wellness and longevity therapies I personally use, and how I decide what’s worth trying

 Why the pursuit of optimal health can sometimes become unhealthy

 What I’m still trying to understand about myself at this stage of my life

I’ve spent much of my life trying to understand how we can live longer and feel better. But nearly losing my own life reminded me that health isn’t the destination. It’s what allows us to be present for the people we love, remain curious, and experience our lives more fully. I hope this conversation encourages you to ask yourself what you want your health to make possible.

I've Had 6 Back Surgeries And Almost Died: Here's What 40 Years of Medicine Actually Taught Me

With the Labour Day long weekend here, we’re bringing back one of our most popular Office Hours episodes on what really happens to your body when you take a break from alcohol. Whether you’re drinking less this weekend or simply curious about how quickly your body can recover, this conversation is worth revisiting.

Today I discuss:

 What alcohol really is—and why the “buzz” is actually your brain slowing down

 How alcohol affects neurotransmitters like GABA, dopamine, and glutamate

 Why even moderate drinking disrupts sleep, mood, hormones, and metabolism

 How alcohol impacts the liver, gut microbiome, immune system, and cancer risk

 Why hangovers feel like the flu—and what’s actually happening in your body

 What happens when you stop drinking, week by week, from detox to deep repair

 The surprising benefits to energy, focus, skin, sleep, and emotional resilience

 Practical tools to manage cravings, social pressure, and sleep disruption

 Why community support makes behavior change easier and more sustainable

Your body has an incredible ability to heal and often, it just needs you to take your foot off the gas. Try it for 30 days. You may be amazed by how different you feel.
If you want extra support, join us for the Hive January Challenge, where we’ll guide you through the process, track progress, and share experiences together.

Encore - What Happens to Your Body When You Stop Drinking for 30 Day

We hear a lot about improving gut health through food, probiotics, and supplements. But after more than a decade of major advances in microbiome research, the picture has become both more promising and more complex.

In this episode, I’m joined by gastroenterologist and neuroscientist Dr. Emeran Mayer, co-author of the new book The Mayer Model, to explore how our understanding of the gut-brain connection has evolved—and what we may still be getting wrong. We also look at what this growing field could mean for chronic disease and healthy aging.

Here’s what you’ll learn:

 How your gut microbiome communicates with your brain, immune system, hormones, and metabolism

 Why diet alone may not be enough to improve gut health—and how sleep, stress, exercise, relationships, and purpose also shape your microbiome

 How modern diets and lifestyles have created a mismatch between our microbes and human biology

 Why probiotics and microbiome testing may not provide the personalized answers many people expect

 How fiber, polyphenols, fermented foods, and greater plant diversity help support a healthier, more resilient microbiome

The food we eat matters, but so do the ways we move, sleep, manage stress, and connect with others. Supporting gut health isn’t about finding one magic solution. It’s about creating a healthier, more resilient system over time.

Beginning September 1, Dr. Mayer’s team is offering my audience a collection of bonuses to accompany The Mayer Model. To learn more about the book and access the bonuses, click here.

What We Got Wrong About the Gut Microbiome (And What's Actually Right)

ADHD is usually treated as a problem in the brain. But what if some of the factors making it harder to focus, regulate your mood, or manage your symptoms are actually coming from somewhere else in your body?

In this episode, I’m joined by one of my producers, Emma, to explore ADHD through a functional medicine lens. We look beyond the diagnosis to ask what may be happening “under the hood”—from the gut and microbiome to inflammation, nutrient deficiencies, blood sugar, hormones, and the foods we eat. Because the brain doesn’t operate in isolation. What happens throughout the body can directly influence how it functions.

Here’s what we discuss in today’s episode:

 The surprising connection between your gut and your ability to focus—even if you have no digestive symptoms

 What I look for beyond the brain when someone comes to me with ADHD

 The everyday foods and nutrient deficiencies that may be quietly making ADHD symptoms worse

 Why two people with the same ADHD diagnosis may have completely different underlying drivers

 What caffeine, skipping breakfast, food dyes, sugar cravings, and menopause may mean for ADHD symptoms

 Where I would start if an adult came to me newly diagnosed with ADHD

ADHD may begin with symptoms in the brain, but that doesn’t mean the brain is the only place we should look. By understanding the connections between diet, gut health, inflammation, nutrients, hormones, and brain function, we can start asking a more useful question: What is making it harder for each person’s brain to function at its best?

ADHD Is a Whole-Body Problem: What to Look at Beyond the Brain

ADHD can go unnoticed for decades, especially in women who learn to compensate through perfectionism, overpreparing, and working under pressure. It often isn’t until the demands of work, motherhood, or another major life transition become too much that the underlying struggle comes into view.

In this episode, I sit down with ADHD counselor Jenna Free, author of The Simple Guide to ADHD Regulation, to explore what she calls the frantic-crash cycle. She explains how chronic fight-or-flight may intensify ADHD symptoms and why nervous system regulation can make other tools and strategies easier to use.

You’ll learn:

 Why women and high achievers can compensate for ADHD for decades before their usual coping strategies stop working

 How perfectionism, procrastination, and working under pressure can keep the frantic-crash cycle going

 The physical signs of nervous system dysregulation, including shallow breathing, muscle tension, and rushing even when there’s no real urgency

 Why calming your body is only the first step in creating lasting change

 How you can move away from all-or-nothing behavior and build a more sustainable way of getting things done

A diagnosis can help you understand how your brain works, but it doesn’t have to define what’s possible. By learning to recognize and regulate survival mode, you can create the conditions for your brain to work at its best.

How to Actually Calm an ADHD Nervous System (And Change Your Life)

Chronic inflammation may be one of the biggest forces accelerating how we age—and the surprising part is that many of the things keeping it switched on are happening every day. Poor sleep, chronic stress, blood sugar spikes, visceral fat, and ultra-processed food can keep your immune system acting like it’s under constant threat, potentially contributing to everything from metabolic dysfunction and heart disease to arthritis and cognitive decline.

Here’s what I unpack in today’s episode:

 The hidden “inflammation switch” scientists are studying and why it may help explain how chronic inflammation drives aging and disease

 The everyday habits that can keep your immune system stuck in a constant state of alarm

 The surprising connection between mitochondrial health, visceral fat, blood sugar, and inflammation

 The most effective ways to help calm chronic inflammation and the simple daily shifts that may have the biggest impact

Inflammation isn’t the enemy—it’s one of your body’s most important survival tools. The problem is when the alarm never switches off. By changing the signals you send your immune system every day, you can help restore balance and support healthier aging from the inside out.

Inflammation isn't Something to Eliminate. It's Something to Regulate

By the time memory begins to slip, the changes affecting the brain may have been developing for decades. But the trajectory isn’t fixed, and many of the factors driving it are within our control.

In this episode, I sit down with my longtime friend and mentor Dr. David Perlmutter, six-time New York Times bestselling author whose new book, Brain Defenders, rethinks what it really takes to protect the brain as we age.

You’ll learn:

 Why protecting your brain should begin long before memory problems appear

 How your daily choices influence whether the brain’s immune cells shift into a protective or damaging state

 Which numbers to know now, including fasting insulin, blood sugar, and waist-to-hip ratio

 How food, exercise, sleep, gut health, and environmental toxins shape your brain’s future

 What emerging research reveals about slowing—and even improving—cognitive decline

I’ve always appreciated how David’s work replaces fear with something far more useful: a clearer understanding of how the choices we make today can help protect our memory, independence, and quality of life for years to come.

Don't Wait for Alzheimer's — A Neurologist's 30-Year Plan to Protect Your Brain

Healthy skin isn't built in your bathroom—it’s built inside your body. While most people focus on creams, collagen powders, and cosmetic treatments, the biggest drivers of wrinkles, sagging, and loss of elasticity are happening at the cellular level.

In today's episode, I discuss:

 Why blood sugar may be aging your skin faster than the sun and the hidden process that damages collagen from the inside out

 The surprising connection between muscle, metabolism, and firmer, healthier-looking skin (especially after weight loss)

 How your body's natural cellular repair system helps slow the aging process and the habits that activate it

 The biggest everyday factors accelerating skin aging, and the science-backed strategies that help protect your skin for years to come

Healthy skin isn't something you can simply apply—it's something your body creates. By improving your metabolic health, protecting collagen, building muscle, reducing inflammation, and supporting your cells, you can help your skin stay stronger, healthier, and more resilient from the inside out.

Your Skin’s Worst Enemy Isn't the Sun - It's Your Metabolism!

Who in the world would try to lower their cholesterol by eating an entire sleeve of Oreos every day for a month? Meet Nick Norwitz, PhD, an Oxford graduate and Harvard medical student who did just that—in an effort to test a hypothesis about cholesterol and metabolic health.

After reversing a serious inflammatory condition with a ketogenic diet, Nick saw his LDL cholesterol spike. Instead of panicking, he turned to research—and self-experimentation—to better understand what those numbers really meant.
In this episode of The Dr. Hyman Show, we explore:

• The health crisis that led Nick to a ketogenic diet

• Why his LDL cholesterol jumped—and what questions it raised

• The Oreo experiment and what it did (and didn’t) reveal

• The nuance around LDL, metabolic health, and cardiovascular risk

• What the science—and Nick’s own experience—suggests about meat, veganism, and finding a diet that works

Check out the episode to hear this fascinating conversation.
