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.
00+ 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 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-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.
