*FREE WITH AUDIBLE MEMBERSHIP TRIAL* The Longevity Nutrient: The Unexpected Fat That Holds the Key to Healthy Aging Unlock the secret to longevity with Dr. Stephanie Venn-Watson’s groundbreaking research of the molecule C15:0—an essential fat found in whole milk, cheese, and fatty fish—that can improve your health and increase your lifespan. The hunt for the holy grail of healthy aging has been ongoing for hundreds of years, and Dr. Stephanie Venn-Watson may be its most unlikely champion. As a veterinary epidemiologist, she was recruited by the US Navy to lead a clinical research program to improve the health of Navy dolphins. Using advanced biotechnology to study the healthiest aging dolphins, she discovered C15:0, a saturated fat which has the potential to expand both the health-span and lifespan in long-lived mammals.
