Research Overview
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.
Taurine
Taurine has a strong mechanistic literature in aging biology and recent high-profile work connecting taurine deficiency with aging phenotypes. Human supplementation is common, but anti-aging claims remain investigational.
