Today, we’re diving into a discovery that could reshape how we think about aging—C15, a newly identified essential fatty acid that plays a crucial role in cellular resilience, inflammation control, and longevity.

For decades, we’ve been told to avoid saturated fats, but what if that advice led to widespread nutritional deficiencies? Dr. Stephanie Venn-Watson, a veterinary epidemiologist and co-founder of Fatty15, uncovered C15’s role in strengthening cell membranes, reducing oxidative stress, and even influencing epigenetic aging—all from studying long-lived Navy dolphins.

In this episode, we break down how C15 protects against cellular fragility, fights ferroptosis (a newly identified form of cell death), and why it’s critical for maintaining healthy skin and metabolic function. We’ll also explore why modern diets have nearly eliminated this nutrient—and what that means for your long-term health.

Dr. Venn-Watson’s research spans over 100 peer-reviewed studies, leading to the first essential fatty acid discovery in nearly a century. Her work is redefining how we approach nutrition, longevity, and skin health at the molecular level.
