Is Your Dog Slowing Down… or Sending You a Sign?
Slower days and more frequent trips to the vet can seem like normal aging, but they’re often signs of deeper cellular decline. Without the right foundation, inflammation, metabolic imbalances, and reduced mobility can quietly take hold long before serious signs of aging appear.
The Scientific Approach to Lifelong Wellness
Longevity15™ is powered by C15:0, an award-winning, science-backed fatty acid shown to strengthen cells, reduce inflammation, and promote healthy immune and metabolic function. This daily supplement supports your dog’s body from the inside out: boosting energy, mobility, and overall wellbeing.
It’s not a band-aid. It’s a long-term solution to help your dog feel better and stay by your side, tail wagging and totally thriving.

Frequently Asked Questions
-
C15:0 (also known scientifically pentadecanoic acid) is a key odd-chain saturated fatty acid that helps maintain your dog’s cellular health as they age. It helps strengthen cell membranes, supports immune and metabolic function, may reduce age-related inflammation, and supports health at the cellular level.
-
Not likely. While trace amounts of C15:0 exist in butter, whole milk, and some fish, the levels are minimal and often paired with less desirable fats. Most modern dog diets lack C15:0 entirely. That’s why Longevity15 uses Fatty15®, a pure, vegan-friendly form of C15:0 that’s safe, stable, and effective.
-
Fatty15 works differently than omega-3s: It complements them rather than replaces them. While omega-3s are used to make short-term signaling molecules, C15:0 gets absorbed directly into cells to strengthen membranes and support long-term function. Together, they help reduce inflammation, support brain and heart health, and promote healthier aging.
-
C15:0 has been shown to help reduce liver fat and inflammation — key factors in fighting metabolic diseases. It helps regulate lipid metabolism and supports healthy liver enzyme activity, offering protection against age-related liver stress and dysfunction.
-
Fatty15 activates AMPK, a master regulator of cellular energy. By doing this, C15:0 helps balance blood sugar, improve fat metabolism, and reduce inflammation, all of which may contribute to a healthier weight and reduced risk of metabolic conditions as your dog ages.
