Research Overview

Urolithin A

Urolithin A has both animal and human data showing effects on mitochondrial biomarkers and physical performance-related endpoints. It is one of the more promising mitochondrial-targeted longevity compounds in current literature.

Metformin

Metformin has extensive human data and remains a leading candidate in geroscience research. Observational and mechanistic studies suggest it may influence pathways tied to aging, though definitive anti-longevity proof in healthy humans is still lacking.
