Fatty15 is a daily supplement that provides pure C15:0, also called pentadecanoic acid. C15:0 is an odd-chain saturated fatty acid found naturally in small amounts in certain foods. Research has identified it as an essential fatty acid, meaning the body needs it but cannot produce enough on its own.
Fatty15 contains a purified, patented form of C15:0, developed for stability and consistent intake. Unlike some fats, C15:0 is resistant to oxidation, which helps it remain stable over time. Studies have explored how dietary C15:0 contributes to maintaining normal fatty acid levels in the body.
Taken daily, this simple capsule offers a practical way to supplement essential dietary fats as part of a balanced routine.
C:15 can be found in most foods, but it is typically mixed with much higher levels of pro-inflammatory fatty acids. Fatty15 stands apart by providing a pure, patented, and bioavailable form of C15:0, without the additional fats commonly found in dietary sources. Developed through extensive scientific research, this award-winning ingredient offers a consistent and controlled way to supplement C15:0. It’s a single-ingredient formulation rooted in purity, quality, and research integrity.
Fatty15 was founded by Dr. Stephanie Venn-Watson and Dr. Eric Venn-Watson, whose backgrounds in veterinary epidemiology, public health, and military medicine inspired a new approach to wellness. Their work with marine mammals led to the discovery of fatty acid C15:0 (FA15™), which became the foundation of the brand’s innovation. Built on scientific research and a shared vision for progress, Fatty15 reflects a commitment to bridging science and everyday wellbeing.
