Research Overview
Rapamycin
Rapamycin extends lifespan in multiple model organisms and is a cornerstone compound in longevity biology. Human studies focus on immune function, inflammation, and age-related biomarkers rather than proven lifespan extension.
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.
