Pet’s Best Life is responsible for bringing Longevity15 to market. Powered by fatty15, Longevity15 is the world’s first supplement for dogs with the ingredient C15:0 (pentadecanoic acid), which is a healthy, odd-chain saturated fatty acid that our bodies require to maintain physiological health.

Studies support that C15:0 is a pleiotropic nutrient that has multiple mechanisms of action and cell-based activities. Numerous studies have shown the relevance of C15:0 to metabolic, cognitive, immune, liver and heart health.

C15:0 is considered beneficial for pets, particularly dogs, as an essential fatty acid that supports cellular health, improves mitochondrial function, and reduces inflammation to promote longevity. As dogs cannot produce enough C15:0 on their own, supplementation helps strengthen cell membranes, supports liver/heart health and fights age-related damage. While small amounts of C15:0 are found in whole-fat dairy products, the Longevity15 supplement is specifically designed to deliver a pure, highly bioavailable form for dogs. It is particularly useful for aging pets to combat cellular decline, but is beneficial for all life stages.
