Dr. Stephanie Venn-Watson: The Secret Fat That Beats Omega-3, Slows Aging & Fights Disease

What if everything we thought we knew about fat is wrong—and one molecule could change how we age, heal, and live? In this cutting-edge episode of SuperLife with Darin Olien, Darin is joined by Dr. Stephanie Venn-Watson, a veterinary epidemiologist, former Navy scientist, and co-founder of Fatty15. Together, they unpack the discovery of C15:0, the first essential fatty acid identified in 90 years, and the tidal wave of science supporting its impact on longevity, inflammation, metabolic health, and cellular survival. From accidental dolphin data to peer-reviewed clinical trials, Dr. Steph reveals how C15 could become one of the most important health breakthroughs of our time.
