Fatty15 delivers whole body and mind health at the cellular level
C15:0 is the first essential fatty acid to be discovered since the omegas—over 90 years ago. Fatty15 contains a pure, patented, award-winning, C15:0 powder called FA15™.
Fatty15 has 3X more cellular benefits than the purest, highest performing omega-3 (EPA).
Here’s what the science shows:
Fatty15 is better at restoring cellular health
+0
More cellular benefits than omega-3.
Fatty15 and EPA share 10 common clinically relevant benefits. However, fatty15 has an additional 26 benefits EPA doesn’t.
83%
More cell types repaired.
Fatty15 repairs 83% of the 12 cell types tested. EPA only repairs 33%.
12/12
More cell types protected.
Fatty15 was safe to all cells at all concentrations. EPA was toxic to 4 of the 12 cell systems tested (including lung and blood vessel cells) when at it’s highest dose.
Fatty15 is safer for your cells
Healthy cells that power a healthy you
Fatty15 makes our cells stronger and more stable. So they’re less likely to show signs of breakdown with age.
Oxidative stress from omega-3 EPA
This stress, caused by EPA, can lead to a pro-inflammatory response. Fatty15 does not have an oxidation risk.
Cell damage or death from omega-3 EPA
Over time oxidation can result in cellular fragility or death — leading to age-related cellular breakdown.

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 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.*

Can’t I just get C15:0 from food?
Our primary food-based source of C15:0 is whole fat cow’s milk, which contains trace amounts of C15:0. Dairy fat, however, contains much higher levels of pro-inflammatory even-chain saturated fatty acids (C16:0), as well as a wallop of calories. Food-based C15:0 is also tied up in complex lipids called triacylglycerides that make C15:0 less bioavailable. We developed fatty15 to help consumers get >99.5% pure C15:0 in a vegan-friendly, science-backed and readily bioavailable form. No cows or calories needed.
-
Can fatty15 replace my omega-3s?
You may be surprised to hear that the most recent studies show that taking omega-3 fish oil supplements does not significantly reduce the risk of developing heart disease, depression or mood disorders, frailty, autoimmune disease, dry eye disease or cognitive decline. This is likely because omega-3 fish oil supplements can be highly variable in omega-3 content and are particularly susceptible to lipid peroxidation, both of which can compromise the quality and effectiveness of omega-3 supplements.
In contrast, fatty15 was developed by doctors to provide a >99.5% pure, science-backed, vegan-friendly, patented and award-winning C15:0 ingredient. Pure C15:0 is an essential fatty acid and a stable powder that is resistant to lipid peroxidation. Each and every batch of fatty15 is tested to guarantee its purity, helping to ensure that you are getting only the good, essential fat that you need. Further, fatty15 has been shown to have 3x more cellular benefits than even the purest, highest performing omega-3.
Given the above, most people can consider fatty15 as a replacement for their omega-3 supplements to support their general, long-term health. If you are taking omega-3s under the supervision of a physician, however, we recommend that you talk with your doctor before making any changes.

How does fatty15 help to restore sleep and reduce anxiety?
While C15:0 is an essential nutrient to support our long-term body health, the latest science is revealing how fatty15 supports our mental health, too. First, the >99.5% pure C15:0 ingredient in fatty15 naturally activates PPARɑ receptors throughout our body and brain that can help to reset our circadian clocks, increase the amount of deep sleep we get, and lower our anxiety. Second, fatty15’s 36+ clinically-relevant cellular benefits have a 78% match to leading mood-supporting compounds. Finally, our bodies use C15:0 to make a second molecule that fully activates both CB1 and CB2 receptors, which can help to deepen sleep, reduce anxiety, and increase joint comfort.*

How does fatty15 help rebalance metabolism?
Today, more than 50 peer-reviewed scientific studies have linked C15:0 (aka, pentadecanoic acid) to better metabolic, heart, immune and liver health. Our >99.5% pure, vegan-friendly C15:0 fatty acid in fatty15 rebalances our metabolism naturally by 1) activating PPAR-alpha and delta receptors, the master orchestrators of our metabolism, 2) activating AMPK pathways, which regulate glucose, 3) repairing mitochondria and enabling our cells to generate energy. Heck, that’s a bunch of much-needed benefits to help keep our metabolism balanced.*

How our customers are feeling
My blood test after taking [fatty15] for 6 months [is the] best I have had in 10 years. Low lipids and perfect a1c.
— V.B.
"I feel and look better, sleep better, easy to take. Blood work came back significantly better." - M.B.
My anxiety feels at bay somehow and I feel much, much more leveled out. I’m genuinely in disbelief by how great I feel.
