people are C15:0 deficient
When our cell membranes don’t have enough C15:0, this makes them fragile and leads to ferroptosis, accelerated aging, and affected metabolic, liver, and heart health.
It’s called “Cellular Fragility Syndrome” and it’s the first nutritional deficiency discovered in 75 years. Here’s the good news: Fatty15 can reverse it.*

FAQs
Read more FAQsWhat 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 protect my liver?
Fatty15 is an award-winning and science-backed C15:0 supplement that supports your long-term health, including your liver health, at the cellular level. Numerous studies have shown that both adults and children with higher C15:0 levels have better liver health. Beyond association, fatty15 has been shown to directly protect the liver in relevant models. Specifically, fatty15 is a PPAR-ɑ/δ agonist that promotes liver health by improving the resilience of cell membranes, calming immune responses, and slowing the production of unhealthy liver tissue.* Learn more about fatty15 and your liver health byclicking here.
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.*

Can I test and measure my C15:0 levels?
Yes! We've teamed up with Genova Diagnostics to offer the Fatty15 C15:0 Test, which measures your C15:0 levels. This test helps you assess whether you have a C15:0 nutritional deficiency or at sub-optimal C15:0 levels. Learn more
