Episode Details

On today’s episode, we welcome Dr. Stephanie Venn-Watson, Co-Founder and Co-CEO of Seraphina Therapeutics, the company behind Fatty15. Stephanie is a veterinary epidemiologist, author of The Longevity Nutrient, and one of the world’s leading experts on C15:0 — the first essential fatty acid discovered in over 90 years.
Stephanie’s story starts in an unexpected place: studying aging Navy dolphins. While working to improve their long-term health, she and her team discovered C15:0, a fatty acid that may play a critical role in strengthening cells and supporting healthy aging. That discovery led to years of research, more than 100 peer-reviewed studies, dozens of patents, and ultimately Fatty15 — a science-backed supplement designed to support cellular health, longevity, and overall wellness.
In this episode, Stephanie shares how a breakthrough in dolphin health became a human health innovation, why she believes we have misunderstood certain saturated fats for decades, and what consumers should know about C15:0, cellular fragility, and healthy aging. We also talk about building trust in the crowded wellness space, turning serious science into a consumer brand, and why some of the biggest discoveries come from questioning what everyone assumes is true.
