What Is Spermidine?

Spermidine is a naturally occurring polyamine found in every living cell. It is one of the most studied compounds in the longevity field, primarily for its role in triggering autophagy — the body's built-in cellular recycling process. As we age, spermidine levels decline, which is why supplementation has attracted significant research interest. This is synthetic spermidine trihydrochloride (3HCL) at 99%+ purity, not a wheat germ extract.

Why 3HCL Form at 10mg?

Most spermidine supplements on the market use wheat germ extract, where the actual spermidine content is a fraction of the stated dose. This is pure spermidine 3HCL — what you see on the label is what you get. At 10mg per capsule, this is a meaningful research-grade dose, not a token amount buried in a proprietary blend.
