About this item

  • POWERED BY C15:0 (PENTADECANOIC ACID): The first essential fatty acid to be discovered in over 90 years. This award-winning longevity supplement, developed by scientists over 10 years in collaboration with the U.S. Navy, has 3x more cellular benefits than pure omega-3 (EPA). C15:0 strengthens cells by 80%, improves mitochondrial function by 45% and repairs cells to slow aging-related breakdown and protect long-term health. Clinical Study References: Venn-Watson & Butterworth PLOS ONE 2022
  • SUPPORTED GUT AND LIVER HEALTH: The pure C15:0 ingredient in fatty15 has been studied for its potential to support C15:0 levels, gut microbiome balance, and liver function. Research has also explored its role in red blood cell health over 12 weeks. Clinical Study References: Robinson et al. J Nutrition 2024, Chooi et al.

Interesting supplement with steady, subtle results - Pricey

Michael CollinsNovember 20, 2025

I tried this out of curiosity, and after a few weeks I noticed a mild but steady boost in overall energy and focus. It is not dramatic, but there is a clear sense of feeling a little more balanced day to day. The capsules are easy to take, and there is no aftertaste. It is on the pricey side, but if you are exploring longevity supplements, this one feels thoughtfully made and consistent. Read more

LIFE SAVER!

Shauna SmithNovember 7, 2025

On my 4th month of taking this faithfully and it’s a life saver. As someone who’s struggled with high triglycerides, Fatty 15 has helped me control them as well as improved my overall mood & energy. It’s a little pricy, but 100% worth it and of course I love the quality of the packaging and ease of purchasing. I’ve also recently started to find some relief in my lower back pain caused by my acne medication. If you’re reading this, buy it! You won’t regret it :) Read more

★★★★☆

I re-ordered this.

MOctober 8, 2025

I can’t exactly say if these pills are doing anything for me. I feel good, but that is probably because I have recently been doing all sorts of new things to take better care of myself. But I will say this. First thing in the morning it is the one supplement(of many) I think of. I almost kind of crave it. So that says something to me. I re-ordered, even though it is pretty expensive. That says something to me as well😂 Read more

The Capsule That Changed My Sleep

pNovember 23, 2025

Fatty15: This Tiny Capsule Changed the Way I Sleep Some supplements build trust slowly, their benefits showing up only on lab tests. Others are felt instantly, woven into your day-to-day experience. Fatty15, intriguingly, is both. At the heart of this minimalist capsule is C15:0, a pure, vegan-friendly odd-chain fatty acid—and the first new essential fatty acid to be discovered in nearly a century. Identified while its founder was studying dolphins, C15:0 has since emerged as a powerful tool for modern health. Its science is compelling: it helps regulate circadian rhythms, balancing the body’s internal clock. In my case of one, the result was deeper, more restorative sleep . Beyond sleep, C15:0 supports cellular health, fortifies fragile membranes, and boosts mitochondrial function—the very engines of our energy. I tried Fatty15 after reading about it, noticed nothing immediate, and so when i finished the bottle I didn’t repurchase it. Within days, I realized something was missing. Not insomnia exactly, but the deep sleep I had grown used to had evaporated. I returned to the supplement, and with it came back those long, unbroken stretches of rest. Fatty15 is not marketed as a sleep aid, yet its subtle power lies there for me. It is rare to find a supplement that strengthens cells, supports mitochondria, and just might return you to the kind of sleep you thought was behind you. Sometimes the smallest capsule contains the most profound shift. Read more

Great product but expensive

Inflation driving prices higher. We need to find substitutions. Found Pecorino Romano has C15, just a few teaspoons saves you money. Read more

Don't believe all the hype!

FriscochaseAugust 13, 2025

I took one capsule religiously each day with filtered water and even though I am 4 days shy of a full 3 months, I found absolutely no difference in my well being. The cost is prohibited, it is a joke to charge that much, they need to cut out the fancy packaging including the tinted light green bottle and the simulated wood screw top and lower the prices and make it more affordable, but even doing that, I found no positive change in my overall body health. In the end I'm going back to taking a multi-vitamin with a good B complex, it is cheaper and actually works than this hyped up nothing supplement. I guess I have to be more diligent in reading the reviews because this one was a costly failure. Read more

Waited on this review just to see that it actually works

James WhiteSeptember 2, 2025

I am 67 years old and been taking almost a month. I do open the capsule up every morning and put powder in my mouth with a good glass of water. Don't like plastic going in my system. Anyway product is effective for me at least no side effects, most of joint pain has gone. Seen improvements in my skin and energy level, definitely sleep better! Size is small but since I open the capsule it doesn't matter. Simple to use after I take it with water, I take my vitamin liquid that way I know everything is being absorbed! It is pricey and I definitely don't like that they want you to have a subscription which I won't. Yet I will probably pay the full price to keep using it because the benefits for me are there!

Feeling more energized and less aches and pains.

Lisa QuinnMay 8, 2025

What first drew me to Fatty15 was its main ingredient- C15:0, a fatty acid that’s said to support metabolism, reduce inflammation, and even slow down aging. I loved that it’s based on real science and developed by researchers who genuinely seem to care about helping people feel their best. After taking it daily for a few weeks, I started noticing some real differences. My energy levels felt more steady throughout the day, and I was sleeping better at night. My mood was more balanced, and I wasn’t waking up feeling as stiff in the mornings. I’ve also come across tons of reviews from people who’ve seen improvements in things like cholesterol and liver health, which makes me feel even more confident about keeping it in my routine. And I’ve gotta say- I really appreciate the packaging. It’s simple, thoughtful, and made with glass and bamboo, which clearly shows a commitment to sustainability. It might seem like a small thing, but it really made a great impression. Read more
