C:15 (pentadecanoic acid) has been making waves as a so-called “essential” saturated fat with potential longevity and metabolic benefits. But does the science actually support these claims?
👇 Visit The Proof website for the full show notes and supporting studies. 👇 https://theproof.com/podcast/
In this episode, I sit down with Dr. Bill Harris, a leading fatty acid researcher, to critically evaluate the evidence behind C:15. We explore population studies, human clinical trials, and the marketing claims around Fatty15 to determine whether this is a true breakthrough or just another overhyped supplement.
In this episode, we cover:
• What makes C:15 different from other saturated fats?
• Is it truly the first essential fat discovered in 90 years?
• The science behind C:15’s effects on cholesterol, glucose, and inflammation
• The key human trials investigating C:15 supplementation
• Does C:15 mimic metformin, omega-3s, or rapamycin for longevity?
• The ethics of patenting a naturally occurring fat—science or smart business?
