The Mark Hyman net worth question is deceptively complex. On the surface, estimates range between $10 and $20 million. However, those figures do not account for what might be his most valuable asset: a co-founder equity stake in Function Health, a diagnostics startup that closed a $298 million Series B at a $2.5 billion valuation in November 2025. If Hyman holds even a small single-digit percentage of that company, his true net worth could be multiples of the public estimates.
Born November 22, 1959, in New York, Hyman graduated from Cornell University with a degree in Asian Studies before earning his medical degree from the University of Ottawa. He started as a family physician in rural Idaho. Today he is a CBS News contributor, a Time 100 Health honoree, and arguably the most commercially successful functional medicine practitioner alive. The distance between those two points is where the money story lives.
Mark Hyman Net Worth: The Book Empire
Fifteen New York Times bestsellers generate serious compounding revenue. Titles like “The Blood Sugar Solution,” “Food Fix,” “Eat Fat, Get Thin,” and “Young Forever” have collectively sold millions of copies worldwide. Moreover, each book functions as a marketing funnel. Readers buy the book, then discover the podcast, then purchase the supplements, then sign up for Function Health. The conversion architecture is deliberate and effective.
The Dr. Hyman Show podcast has surpassed 300 million downloads, generating significant advertising revenue. Speaking engagements at the World Economic Forum in Davos and similar venues command premium fees. Consequently, Mark Hyman net worth from media alone likely exceeds $5 million, before accounting for any business equity.
Function Health: The Mark Hyman Net Worth Multiplier
Function Health is the story within the story. Co-founded in 2021, the company offers membership-based lab testing starting at $365 per year, providing over 160 biomarker tests through Quest Diagnostics locations. The company’s growth has been explosive. In June 2024, it was valued at $191 million after a $53 million Series A from Andreessen Horowitz. By November 2025, a $298 million Series B led by Redpoint Ventures pushed the valuation to $2.5 billion.
The investor roster reads like a Hollywood after-party. Matt Damon, Kevin Hart, Zac Efron, Pedro Pascal, Magic Johnson, and Colin Kaepernick have all invested. In addition, Function Health acquired Ezra, an MRI scanning company, in May 2025 to expand into advanced imaging. Since 2023, the platform has processed over 50 million lab tests. As co-founder and Chief Medical Officer, Hyman’s equity position in this company may ultimately be the largest contributor to Mark Hyman net worth.
The Supplement Controversy Behind Mark Hyman Net Worth
Critics point to a structural conflict of interest. Through drhyman.com, Hyman sells roughly 500 dietary supplement products spanning 12 pages on his website. McGill University’s Office for Science and Society describes the catalog as “just about any dietary supplement you can think of.” The concern is straightforward: when the person interpreting your blood tests also profits from selling you supplements, the incentive to find problems increases.
Furthermore, Hyman practices functional medicine, which mainstream medical institutions have questioned. Wikipedia characterizes it as “a form of alternative medicine,” and some critics have compared Function Health to Theranos. Nevertheless, the market has spoken. A $2.5 billion valuation, partnerships with Equinox and the NBA Players Association, and a CBS News contributor role suggest that Hyman’s approach resonates with both consumers and investors regardless of academic skepticism.
Mark Hyman Net Worth: The Power Network
Hyman’s influence extends beyond his personal balance sheet. He is married to Mia Lux, a comedian and wellness advocate. He is a longtime friend of Robert F. Kennedy Jr. He collaborated with Pastor Rick Warren on “The Daniel Plan,” which became a number-one bestseller. His network spans Silicon Valley venture capital, Hollywood celebrity circles, Washington policy, and evangelical Christianity. Therefore, his net worth in pure financial terms understates his total economic influence considerably.
