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.

Spermidine

Spermidine has meaningful preclinical support and a growing human observational literature linking intake with healthier aging metrics. Its core longevity mechanism is thought to involve autophagy and improved proteostasis.
