Research Overview
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.
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.
