Dr. Hillary Lin is a Stanford-trained internist who has stepped into one of medicine’s most hype-filled frontiers: longevity. As co-founder and CEO of Carecore and host of The Longevity Show, she’s working to separate science from marketing in a field where billionaires, biohackers, and influencers often dominate the conversation. Her approach blends clinical rigor with healthy skepticism, offering physicians a practical framework for what longevity medicine actually means.

On this episode of How I Doctor, Dr. Graham Walker talks with Hillary about the pillars of longevity that truly work, the supplements and multivitamins that don’t, and the future of prevention through pre-disease screening and at-home testing. From debunking fads to reframing wellness as evidence-based care, Hillary challenges doctors to rethink their role in guiding patients through this rapidly evolving space.

At its worst, it’s marketing dressed up as medicine. As physicians, we owe it to our patients (and ourselves) to separate evidence from enthusiasm, bringing healthy skepticism and clear clinical reasoning to the conversation.
