Research Overview
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.
Fisetin
Preclinical studies show fisetin can selectively target senescent cells and reduce age-related inflammatory markers. Early human research exists, but definitive anti-aging outcomes in humans are still unproven.
