In this clip, Dr. Howard Sesso, Co-Principal Investigator of the landmark COSMOS trial, breaks down the clinical evidence from over 21,000 participants. We explore the "sweet spot" of nutritional insufficiency; where you aren't clinically deficient but lack the levels needed for optimal healthspan. Dr. Sesso and Dr. Sidong Lee discuss how multivitamins specifically slowed the "epigenetic clock" in individuals with existing risk factors like hypertension and accelerated biological aging. We also cover the importance of "precision nutrition" and why the synergy of essential vitamins and minerals may be more effective than high-dose single supplements. If you’re looking for a common-sense, evidence-based approach to basic supplementation, this deep dive into the Harvard-led COSMOS data provides the answers you need. 📚 Chapters 0:00 The "Insurance Policy" Strategy for Supplements 0:55 Is a Multivitamin a Waste of Money? 1:57 Who Benefits Most?
