If you want to feel better, look healthier and live longer, supplements may be part of your daily wellness routine. But it's rare to find a longevity supplement that's backed by peer-reviewed scientific research.
Fatty15 is the world's first supplement containing pure, patented and bioavailable C15:0. This "longevity nutrient" is the first essential fatty acid to be discovered in over 90 years, and it's been clinically proven over a decade of research to strengthen cells—that means potential benefits ranging from healthier aging and improved lab results to deeper sleep and better energy.
Science-backed longevity support
Fatty15 works by strengthening and protecting your body's 30 trillion cells against lipid peroxidation, which degrades the cell membrane over time. C15:0's cell-armoring process slows down cellular aging—and it's the source of Fatty15's potential to slow age-related breakdown, boost longevity and support long-term health.
Fatty15 was developed by a team of scientists led by co-founder Dr. Stephanie Venn-Watson in collaboration with the U.S. Navy. While researching ways to improve the health and lifespan of Navy dolphins, she discovered C15:0, a naturally occurring essential fat found in milk, cheese and fatty fish.

Since it was first reported in 2020, C15:0's ability to slow biological aging has been validated by peer-reviewed studies. Dr. Venn-Watson co-founded Fatty15 to bring this discovery's potential to extend life and health to the public. She shares the story behind these findings in her recently released Simon & Schuster book, The Longevity Nutrient: The Unexpected Fat That Holds the Key to Healthy Aging.
Results you can see and feel
It's one thing to get results in a lab, but it's another to experience those benefits in real life. After all, you don't just want to live longer—you want to stay healthy, feel good and look youthful while you're at it.
The everyday benefits of Fatty15 may extend far beyond longevity support. In a survey of 2,446 Fatty15 customers, 72% of users felt changes like deeper sleep, calmer mood and better-balanced energy within 16 weeks. Users also reported improved joint comfort and visible effects like healthier-looking hair and skin within this period.
Because it's been clinically proven to raise C15:0 levels, Fatty15 may also result in better health overall. Users have reported better blood test results, including improved biomarkers like hemoglobin levels, metabolic health and red blood cell health—all of which may indicate slower rates of biological aging. Higher C15:0 levels may also lead to other long-term health benefits, including lower LDL cholesterol, a stronger gut microbiome and improved liver function.
Safe, effective and award-winning
Fatty15 isn't the only longevity supplement out there, but it does seem to be the most effective. In a peer-reviewed study, the active ingredient in Fatty15 matched or outperformed three other potential longevity-boosting compounds in more than 36 areas of cellular activity. This means that C15:0's anti-inflammatory, antimicrobial properties may even target accelerated age-related breakdown related to metabolic, heart, immune and liver health—which studies show have been rising in young people in recent years. This essential fatty acid even outperformed a leading Omega-3 fatty acid in one peer-reviewed research study, which found C15:0 to be safer and more broadly effective.

Research also shows that taking Fatty15 may carry lower risks than some other longevity supplements. Clinical trials found no side effects and no safety concerns for long-term use, unlike other cell-supporting compounds like rapamycin. And because C15:0 isn't limited by genetic differences, it's possible that the benefits extend to everyone. Even better, each small, daily capsule of Fatty15 is vegan, gluten-free, lactose-free and allergen-free, and every batch is tested by a third party to ensure its purity.
The possibilities of Fatty15 aren't just backed up by clinical research. The product has more than 5,000 positive reviews from satisfied customers, and it received the Mindful Award in 2025 for Best Overall Supplement.
