Mark Hyman’s net worth is estimated at $30-50 million in 2026, with significant upside from his co-founder equity in Function Health, now valued at $2.5 billion. The functional medicine physician turned startup founder has quietly assembled one of the most interesting wealth profiles in the longevity space. While his peers chase podcast ad revenue and supplement margins, Hyman co-built a company that raised $350 million and counts a16z and Matt Damon among its investors.
Mark Hyman Net Worth: How a Functional Medicine Doctor Built Real Equity
Most health influencers top out at book deals and speaking fees. Hyman did all of that first, then made the move that separates wealth from income. He co-founded Function Health in 2021, a membership-based lab testing platform offering 160+ biomarker tests for $365 per year. By November 2025, the company closed a $298 million Series B at a $2.5 billion valuation led by Redpoint Ventures.
That valuation shift tells you everything. Function went from $191 million in mid-2024 to $2.5 billion in eighteen months. As co-founder and Chief Medical Officer, Hyman’s equity stake could be worth hundreds of millions depending on dilution. The company has completed over 50 million lab tests since launch and acquired AI-powered MRI scanning company Ezra in May 2025.
The Revenue Stack: Books, Podcast, Supplements, and Platform Equity
Hyman’s income streams layer on top of each other in ways that compound. Fifteen New York Times bestsellers generate ongoing royalties across 43 languages. His podcast, The Doctor’s Farmacy, pulls millions of monthly downloads. Speaking engagements reportedly command six-figure fees. And his supplement business through drhyman.com sells roughly 500 products across 12 pages of offerings.
That supplement operation has drawn scrutiny. McGill University’s Office for Science and Society described the catalog as “just about any dietary supplement you can think of” organized into “a confusion of stacks.” The criticism centers on a structural conflict: diagnosing problems through Function Health while profiting from selling the remedies. When the person interpreting your blood tests also sells the supplements, the incentive architecture gets complicated.
Function Health: The Real Wealth Multiplier
Forget the book royalties. Function Health is where the generational wealth lives. The company’s investor roster reads like a Davos guest list: Andreessen Horowitz, Battery Ventures, Nat Friedman and Daniel Gross’s NFDG, plus celebrity capital from Magic Johnson, Zac Efron, and Pedro Pascal. In 2025, Function was named to TIME’s Most Influential Companies list.
The November 2025 funding round also introduced Function’s Medical Intelligence Lab, a generative AI model designed to synthesize lab tests, imaging data, wearable metrics, and medical records into personalized health insights. Hyman and Chief Medical Scientist Dan Sodickson co-direct the effort. If the AI play works, Function stops being a testing company and becomes a health intelligence platform. That distinction could mean another zero on the valuation.
Career Timeline: From Rural Idaho to CBS News Contributor
Hyman’s path from emergency room doctor to longevity mogul followed a particular arc. Cornell undergraduate degree in Asian Studies. Medical degree from the University of Ottawa. Early career as a family physician in rural Idaho and later an ER doctor in Massachusetts. Then the pivot: co-medical director at Canyon Ranch from 1996 to 2004, where he discovered functional medicine and never looked back.
In 2014, he founded the Center for Functional Medicine at the Cleveland Clinic, giving functional medicine its first foothold in mainstream academic medicine. He made the Time 100 Health list in May 2025. By January 2026, Bari Weiss hired him as a contributor to CBS News, giving him broadcast reach alongside his digital empire.
Controversies and the Functional Medicine Debate
Hyman operates in contested territory. Functional medicine itself remains controversial in mainstream medical circles. Critics call it a form of alternative medicine without definitive clinical evidence of effectiveness. His collaboration with Robert F. Kennedy Jr. on a 2014 book about thimerosal raised eyebrows, though Hyman reportedly convinced Kennedy to remove chapters incorrectly linking the compound to autism.
More recently, on The Diary of a CEO podcast, Hyman made claims about autism being caused by gluten or childhood vaccines, statements that conflict with widely accepted scientific evidence. His promotion of the pegan diet (a paleo-vegan hybrid) has been characterized as a fad diet by registered dietitians. Yet his following continues to grow, suggesting the market doesn’t penalize controversy the way the medical establishment does.
The RFK Jr. Connection and Political Capital
Hyman’s longtime friendship with Robert F. Kennedy Jr., now HHS Secretary, adds a dimension that’s hard to price but impossible to ignore. When the person who oversees federal health policy considers your co-founded company a model for proactive health, the regulatory environment tends to be friendly. Function Health’s vision of consumer-directed lab testing aligns neatly with Kennedy’s “Make America Healthy Again” framework.
This political proximity cuts both ways. It accelerates certain opportunities while creating reputational risk depending on which way the political winds shift. For now, the alignment appears to be net positive for Function’s growth trajectory.
What Mark Hyman’s Net Worth Tells Us About the Longevity Economy
Hyman’s wealth trajectory maps perfectly onto the longevity era’s central thesis: the real money isn’t in telling people what to eat. It’s in owning the platform that tells them what’s wrong. Function Health sits at the intersection of consumer health anxiety and venture-scale ambition, and Hyman positioned himself at the center of both.
