In this episode of The Human Upgrade, Dave Asprey is joined by Dr. Stephanie Venn-Watson, a veterinary epidemiologist and co-founder of Seraphina Therapeutics, to explore the groundbreaking discovery of C15, also known as Pentadecanoic acid. This episode uncovers how Dr. Venn-Watson's work with aging dolphins in the U.S. Navy led to the surprising revelation that C15 is an essential fatty acid, marking the first discovery of its kind in nearly a century. Through extensive research, C15 has shown powerful benefits for longevity, reducing inflammation, and promoting cellular health, which can help prevent chronic conditions like metabolic syndrome and heart disease. Dr. Venn-Watson explains the science behind C15, its natural sources—such as grass-fed dairy and certain types of fish—and why it’s often missing from modern low-fat diets. She also dives into the clinical studies that reveal how C15 can stabilize cell membranes, reduce oxidative stress, and improve metabolic function. The episode emphasizes th
