Ingredients

Fatty15 contains pure pentadecanoic acid (C15:0). Fatty15 is a science-backed, patented, award-winning, pure and vegan-friendly C15:0 supplement to support your long-term health and wellness.

For whom

C15:0, the ingredient in fatty15, is GRAS (generally regarded as safe) certified, which means fatty15 is safe for children age 4+, pregnant women, nursing moms, and pretty much everyone except for infants and toddlers.

Our bodies tend to build up until we are about 30 years old. After 30, our bodies start to break down due to increasingly fragile cells, less efficient mitochondria, and an increased need to support immunity and metabolism. By our 40s, these changes can impact health and may require pills to address them. As we age from 65 on up, we can become increasingly fragile and fatigued.

So, taking fatty15 when you’re younger may help keep your healthy body healthy…when you’re 30 to 65, it can help your body be more resilient…and when you’re older than 65, it can provide extra support to help restore some of that resilience and energy.*

How to use

Fatty15 should be taken daily. We recommend that you start with 1 or 2 capsules, and can be taken either with food or on an empty stomach. It is just that versatile of a supplement!

C15:0 (pentadecanoic acid) is a healthy odd-chain saturated fatty acid. Fatty15’s co-founder, Dr. Steph Venn-Watson, discovered that C15:0 is not only a good fat, but that C15:0 meets the rare criteria of being the first essential fatty acid to emerge since omega-3, which was over 90 years ago.

00+ peer-reviewed studies have been published relevant to C15:0’s health benefits, including how C15:0 has 36+ cellular activities that support metabolic, heart, liver, cognitive, red blood cell and immune health.

Essential fatty acids are nutrients that our bodies need to maintain baseline health, but can’t make enough on their own. That means we must get these essential fats from our diet or supplements. Because C15:0 has been shown to have a wide range of cellular benefits, C15:0 is emerging as the essential, essential fatty acid.*

While C15:0 can be found in some foods, it's mixed with much higher levels of pro-inflammatory fatty acids. Fatty15 provides a pure, patented, science-backed, award-winning and bioavailable C15:0 ingredient.

Fatty15 (C15:0) is an odd-chain saturated fatty acid, while omega-3s are polyunsaturated fatty acids. While both are beneficial fats that support healthy immune responses, they also have very different roles. For example, fatty15 is a sturdy fat that strengthens our cell membranes and protects them against age-driving lipid peroxidation. In contrast, omega-3s are less stable fats that make our cell membranes flexible but more susceptible to oxidation, especially as we age. The bottom line: Our bodies use both C15:0 and omega-3s to stay healthy, and they can and should compliment each other. The upsides of fatty15 with pure C15:0? Tiny pills with no smell, no taste, and no burps. Better yet, when tested head-to-head against pure EPA, fatty15 had 3x more cellular benefits relevant to our immune, metabolic, heart, and liver health. We recommend working with your healthcare provider to determine what supplement stack is best for you.

Fatty15 activates PPARs, which support healthy liver function. Cell-based and in vivo studies have shown that the pure C15:0 ingredient in fatty15 effectively protects liver cells against lipid peroxidation and pro-inflammatory cytokines. People with higher C15:0 levels have healthier liver function.*

C15:0 activates metabolic pathways that support healthy glucose and lipid metabolism, helping maintain balanced energy levels.*

Yes! Your doctor can order a fatty acid panel, which includes C15:0. Additionally, we partnered with Genova Diagnostics to offer an at-home C15:0 test. These tests measure your C15:0 levels, which allows you to fix nutritional C15:0 deficiencies, optimize the strength of your cells and slow the aging of your cells.

    I’m a happy fatty15 camper!

    I now feel like that dehydrated house plant that finally got watered! It feels like my cells are pulsing with life force energy again. It’s hard to describe all the multiple little changes that have added up to this new found strength on so many levels. And at 70, I’m so grateful. So, I’m a happy fatty15 camper right now and look forward to more regenerative benefits as I continue the journey of a wholesome lifestyle.

    Love fatty15!

    Actually, I've been taking it for over a year now. And, on the advice of my naturopathic doctor, I take a host of supplements already. However, after hearing that I had added Fatty15, she recommended that I now take 2 a day. So for the fact that I'm 74 years old (almost 75!) and have survived both breast and uterine cancer, I'm doing remarkably well and have more energy than most who are my age. And for sure, Fatty15, along with my other supplements definitely factors in to my overall health!

    The only supplement I subscribe to!

    Fatty 15 is the only supplement I subscribe to and would never be without. I say this because it’s made a palpable difference in how I feel. The anecdotal evidence for me took a few months or so to register. But I realized I was no longer having trouble sleeping, my brain fog had cleared, I felt more content, had more energy, and overall felt younger! My hair and skin even looked younger! So since I had not changed my diet, or added or changed other supplements; I concluded it must be the result of Fatty 15. I had had a comprehensive lab panel done a month or two prior to starting Fatty15, which I’ve now been taking about 15 months. I will soon be scheduling another identical lab panel to be taken when I return from traveling. I expect to have increased positive results, like so many other reviewers have had. I recommended Fatty15 to all of my friends and family. It’s been a game changer!

    This supplement has made a remarkable difference

    I've been taking Fatty-15 for close to a year, possibly slightly longer. During that time, I seem to have more energy, more initiative and a greater sense of well-being. I appreciate the rigorous and very reassuring science backing this supplement although I do find myself wondering how is it possible one little pill can make so much difference!

    The lab results are in!!!

    I timed taking these 2 months before having blood work so I could compare. My liver enzymes were way off 2 months ago. They have changed dramatically! I am so impressed with Fatty c 15, my A1C also came down. I am on automatic delivery, it has passed my test so I will continue!!!
