What is Fatty15?
Fatty15 is a science-backed longevity supplement that contains pure C15:0, an essential fatty acid shown to support cellular health and slow aging. It’s the only supplement of its kind and is backed by over 100 peer-reviewed studies. While most people aren’t getting enough C15:0 from their typical diets, Fatty15 helps restore levels and protect your cells from age-related breakdown.
The Fatty15 Healthy Aging Supplement 90-Day Starter Kit is designed to support cellular health and longevity. Its hero ingredient, C15:0 (pentadecanoic acid), has been clinically shown to:
- Strengthen cell membranes
- Slow biological aging
- Improve resilience against age-related breakdown
In fact, when tested against well-known longevity compounds like rapamycin, metformin, and acarbose, C15:0 outperformed them all, activating more than 36 clinically relevant cellular pathways.
