Fatty15: Is This “New Essential Fatty Acid” Worth the Hype?

Unlike omega-3s, which are polyunsaturated and more prone to oxidation, C15:0 is a stable, saturated fat that integrates directly into cell membranes. It also activates receptors involved in inflammation resolution (PPARs) and appears to support mitochondrial function, much like omega-3s—potentially with fewer downsides at higher doses. That said, omega-3s are still incredibly well-researched and beneficial. Fatty15 may not replace them, but could work as a complementary support, especially for individuals with mitochondrial dysfunction, chronic inflammation, or metabolic imbalances.

Pentadecanoic Acid (C15:0), an Essential Fatty Acid, Shares Clinically Relevant Cell-Based Activities with Leading Longevity-Enhancing Compounds

Pentadecanoic acid (C15:0), an odd-chain saturated fatty acid, has mounting evidence of being essential to supporting cardiometabolic and liver health. People with low circulating C15:0 concentrations have a higher risk of having or developing type 2 diabetes, heart disease, nonalcoholic fatty liver disease, and nonalcoholic steatohepatitis, as well as specific types of cancer

What is C15:0 fatty acid (found in fatty15), and does it have health benefits?

C15:0 fatty acid, also called pentadecanoic acid and found in the supplement fatty15, is a saturated fatty acid naturally present in dairy fat, ruminant meats (e.g., beef, bison, and lamb), and some fish and plants (Venn-Watson, PLoS One 2022). C15:0 fatty acid in fatty15 (which suggests taking one 100-mg capsule daily) is promoted for "healthier hair & skin, balanced metabolism, and deeper sleep," as well as "slowing the aging process" and "optimizing red blood cell production," but there are no clinical studies to support these uses.

If you’re not familiar with it, Fatty15 is a supplement centered around a saturated fatty acid called C15:0 (pentadecanoic acid). It's being marketed as a “new essential fatty acid” that can reverse aging, improve cellular function, and reduce inflammation.

I tried fatty15 supplements during a particularly busy three-week span of travel, time changes, and activity-packed days where I couldn’t do my normal routine as a yoga instructor.

Since it was easy to take, I’ve been super consistent and I’m looking forward to the longer-term benefits, too.
