Spermidine is a polyamine compound (C7H19N3) found in ribosomes and living tissues and having various metabolic functions within organisms. It was originally isolated from semen. Spermidine is a longevity agent in mammals due to various mechanisms of action, which are just beginning to be understood. Autophagy is the main mechanism at the molecular level, but evidence has been found for other mechanisms, including inflammation reduction, lipid metabolism, and regulation of cell growth, proliferation, and death.
