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.
Urolithin A
Urolithin A has both animal and human data showing effects on mitochondrial biomarkers and physical performance-related endpoints. It is one of the more promising mitochondrial-targeted longevity compounds in current literature.
