Fatty15 and C15:0: a new essential fatty acid for cellular health and healthy ageing
C15:0: The New Essential Fatty Acid for Healthy Ageing
C15:0 (pentadecanoic acid)—the unique fatty acid in fatty15—is now proposed as a new essential fatty acid, necessary for baseline physiological health and insufficiently produced by the body.
Its deficiency is linked to "Cellular Fragility Syndrome," which involves fragile cell membranes, cell death (ferroptosis), and impaired metabolic and organ health. Optimizing C15:0 status may be key to addressing this fragility that underlies age-related changes.
C15:0 provides multi-targeted support:
- Metabolic Health: It activates key regulators (PPARs, AMPK, AKT) to support healthier glucose, cholesterol, and liver enzyme levels.
- Cognitive Health: It exerts neuroprotective effects by inhibiting FAAH and MAO-B, enzymes linked to mood, sleep, and the breakdown of dopamine as we age.
For long-term resilience, fatty15 offers a single, science-backed way to restore C15:0 levels and support overall cellular health.
