Research Overview

Pterostilbene

Pterostilbene has supportive preclinical data and smaller human studies across metabolic and oxidative stress endpoints. Its anti-aging potential is plausible, but it is less established than resveratrol or NR.

NR

NR has substantial human and animal research showing reliable NAD+ elevation after oral dosing. Clinical outcomes are still being defined, but it is one of the better-studied longevity-related compounds.
