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.
NMN
NMN has a substantial preclinical and growing human literature centered on raising NAD+ levels. Research is strongest for biomarker changes and metabolic endpoints, while long-term aging outcomes remain under investigation.
