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.

Taurine

Taurine has a strong mechanistic literature in aging biology and recent high-profile work connecting taurine deficiency with aging phenotypes. Human supplementation is common, but anti-aging claims remain investigational.
