Healthy aging breakthrough, discovered by helping dolphins
Did you know that 1 in 3 older dolphins develop the same aging-associated conditions that we do?
While caring for older Navy dolphins, doctors discovered thathigher dietary and circulating levels of C15:0 predicted the healthiest aging dolphins.*Fast forward 10 years and 100+ studies, and we know that C15:0 helps us humans age healthier, too.

Fatty15 delivers a foundational nutrient
C15:0 is the first essential fatty acid to emerge in over 90 years. By delivering a pure and bioavailable C15:0 nutrient, fatty15 supports the strength and stability of our cells at every age and every stage of life.*
GROW: In childhood, higher C15:0 levels are associated with healthier body growth and cognitive development.*
SLOW: In adulthood, fatty15 slows cellular aging and supports better long-term health.*
REVERSE: As we get older, fatty15 is an emerging geroprotector that reverses cellular aging.*
Aging is happening to all of us.
Healthy aging isn’t a “someday” goal, it’s a daily practice. And if we’re being honest, the hardest part of any daily practice is... doing it daily.
That’s why we’re so excited about our expanded fatty15 product offerings, made for adults and kids, so more people can get the benefits of C15:0 in a way that’s simple, enjoyable, and stick-with-it-able.
Fatty15 can slow (and yes, even reverse)
cellular aging.
Here’s how fatty15 supports healthy aging:*
Developed by doctors,funded by the Navy.
Fatty15 was developed to bring a pure, patented and bioavailable C15:0 nutrient to the world that supports healthy aging at all stages of life.*

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, 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
We're aging faster than we should.
But this is fixable.
Our primary dietary source of C15:O, by far, is dairy fat. For decades, society has shifted away from whole dairy fats,resulting in an invisible side effect: drastically lowering C15:0 from our modern diet.
The result? Studies support that low C15:O levels can make
our cells more fragile and may accelerate aging.
Fatty15 isn't just a supplement.It is a restoration.
By delivering pure, bioavailable C15:0, fatty15 is clinically proven to raise C15:0 levels. By doing so, fatty15 can strengthen cell membranes to help support healthy aging for you and your family.*
FAQs
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 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.
100+ 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.*
Can't I just get C15:0 from food?
Can't I just get C15:0 from food?
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.
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 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.
How does fatty15 protect my liver?
How does fatty15 protect my liver?
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.*
How does fatty15 support metabolic health?
How does fatty15 support metabolic health?
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-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.
