Spermidine is a natural polyamine that induces autophagy through AMPK/SIRT1 signaling and eIF5A hypusination, and is a very popular longevity supplement often derived from wheat germ. The human evidence is largely observational, linking higher dietary intake to cardiovascular and cognitive benefits, with only small interventional trials to date. Mechanistically compelling but causal human proof is still thin.
