First Essential Fatty Acid Discovered Since the Omegas
C15:0 is a healthy, odd-chain saturated fatty acid that our bodies require to maintain physiological health.

C15:0 is a breakthrough, goldilocks fatty acid
While omega-3 and omega-6 have been recognized as two essential fatty acids, C15:0 is emerging as the third essential fatty acid. Let’s talk about the differences between the omegas and C15:0.

Polyunsaturated Fatty Acid
Omega-3 and omega-6 fatty acids
Omega-3 and omega-6 are polyunsaturated fatty acids that contain multiple double bonds.
These double bonds are why omega-3 and omega-6 fatty acids are oils which are particularly susceptible to oxidation.
While omega-3 fatty acids have had many proposed health benefits, studies have had mixed outcomes.

In comparison, C15:0 (also called pentadecanoic acid) is an odd-chain saturated fatty acid with no double bonds in the main chain.
This makes C15:0 sturdy and resistant to oxidation.
Studies have recently linked C15:0 to better long-term health, including better heart, metabolic, immune and liver health.

Repairing & Restoring Cellular Health
C15:0 works at the cellular level to reverse key hallmarks of aging, while reducing clinically-relevant drivers of chronic disease.
