Research Overview

Resveratrol

Resveratrol has extensive preclinical literature and a substantial human trial history in metabolic and aging-related endpoints. Results are mixed, but it remains one of the most studied longevity-associated compounds.

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.
