Health leaders recommend fatty15.
“One of my favorite longevity-boosting supplements… fatty15 acts as an armor for your cells, strengthening cell membranes, repairing mitochondria, and reversing the hallmarks of aging…”
Dr. Mark Hyman, The father of Functional Medicine
“Wow, this is massive science. It’s going to help everybody because it’s so fundamental to human health”
Dr. Will Cole, Leading functional medicine expert
“If you use omega-3s, I encourage you to check out…fatty15. One of the most important things that it can do is…to repair actual damage to the cells.”
Thomas DeLauer, Nutrition and Business Performance Coach
“This is part of that building block that you need for everything else to work properly… it’s important and foundational to health.”
Nat Niddam, Holistic nutritionist and longevity educator
"The breadth of evidence for its health benefits is what makes C15:0 so compelling. Very few, if any, candidate geroprotectors have been subjected to the same level of rigor in a wide variety of settings."
Dr. Nicholas Schork, The leader at the National Institute of Health’s Longevity Consortium
FAQs
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 be discovered since omega-3, which was over 90 years ago.
In extensive peer-reviewed studies, C15:0 has been shown to support metabolic, heart, liver and immune health, as well as naturally activate receptors in our bodies that deepen sleep, reduce anxiety, and improve joint comfort.
Essential fatty acids are nutrients that our bodies need to maintain baseline health but can't make. That means we must get these essential fats from our diet or supplements. Today, there are three known essential fatty acids: alpha-linolenic acid (an omega-3), linoleic acid (an omega-6), and now, C15:0. Because C15:0 has been shown to have 3x more cellular benefits than omega-3, 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.
