“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, Functional Medicine Physician and NYT Best Selling Author
“Wow, this is massive science. It’s going to help everybody because it’s so fundamental to human health”
Dr. Will Cole, Senior Functional Medicine Clinic Director
“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, Celebrity Fitness and Nutrition Expert
“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
“Text Under Main Text.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, Leader at the National Institute of Health’s Longevity Consortium
Frequently Asked Questions
What is C15:0?
What is C15:0?
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 notonly a good fat, but that C15:0 meets the rare criteria of being the firstessential 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 supportmetabolic, heart, liver, cognitive, red blood cell and immune health.
Essential fatty acids are nutrients that our bodies need to maintain baselinehealth, but can't make enough on their own. That means we must get theseessential fats from our diet or supplements. Because C15:0 has been shownto have a wide range of cellular benefits, C15:0 is emerging as the essential,
essential fatty acid.
Can'tljust get c15:0 from food?
Can'tljust get c15:0 from food?
While C15:0 can be found in some foods, it's mixed with much higher levelsof pro-inflammatory fatty acids. Fatty15 provides a pure, patented, science-backed, award-winning and bioavailable C15:0 ingredient.
How does fatty15 compare to omega-3?
How does fatty15 compare to omega-3?
Fatty15 (C15:0) is an odd-chain saturated fatty acid, while omega-3s arepolyunsaturated fatty acids. While both are beneficial fats that supporthealthy immune responses, they also have very different roles. For example,fatty15 is a sturdy fat that strengthens our cell membranes and protectsthem against age-driving lipid peroxidation. In contrast, omega-3s are lessstable fats that make our cell membranes flexible but more susceptible tooxidation, especially as we age. The bottom line: Our bodies use both C15:0and omega-3s to stay healthy, and they can and should compliment eachother. The upsides of fatty15 with pure C15:0? Tiny pills with no smell, notaste, 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.
How does fatty15 protect my liver?
How does fatty15 protect my liver?
Fatty15 activates PPARs, which support healthy liver function. Cell-basedand in vivo studies have shown that the pure C15:0 ingredient in fatty15effectively protects liver cells against lipid peroxidation and pro-inflammatory cytokines. People with higher C15:0 levels have healthier liverfunction.
How does fatty15 help rebalance metabolism?
How does fatty15 help rebalance metabolism?
C15:0 activates metabolic pathways that support healthy glucose and lipid
metabolism, helping maintain balanced energy levels.*
Can I test and measure my C15:0 levels?
Can I test and measure my C15:0 levels?
Yes! Your doctor can order a fatty acid panel, which includes C15:0.
Additionally, we partnered with Genova Diagnostics to offer an at-homeC15:0 test. These tests measure your C15:0 levels, which allows you to fixnutritional C15:0 deficiencies, optimize the strength of your cells and slow
the aging of your cells.
