What is Spermidine?

Spermidine is a naturally occurring polyamine compound found in all living cells. It plays a crucial role in cellular growth, repair, and longevity. Spermidine levels decline with age, making supplementation a popular anti-aging strategy. It is well-known for its ability to induce autophagy, the cellular "cleanup" process that removes damaged components and promotes cellular renewal.
