The search for compounds that extend healthy lifespan has intensified over the past two decades. Among the most promising candidates emerging from this research is spermidine, a natural polyamine spermidine found in cells across virtually all living organisms.

Unlike many supplements that rely on theoretical mechanisms, spermidine has accumulated substantial preclinical evidence showing lifespan extension in yeast, flies, worms, and mice. The compound works primarily by inducing autophagy—the cellular housekeeping process that declines with age.
