Spermidine

Varies

Spermidine is a naturally occurring polyamine found in high concentrations in aged cheese, wheat germ, soybeans, and mushrooms. It has gained significant research interest for its ability to trigger autophagy — the cellular process that clears damaged proteins and organelles. Spermidine levels decline with age, which has led to investigation of both dietary and supplemental approaches to maintaining adequate levels.

“In single cells in the lab, spermidine activates a process called autophagy or the cell clearance process. By clearing away those damaged components, we can rebuild new ones.”

Safety & Cautions

Side Effects

Mild gastrointestinal discomfort
Nausea at higher doses
Allergic reactions in wheat-sensitive individuals

Spermidine from wheat germ extract is generally well-tolerated at typical doses, but individuals with wheat allergies or celiac disease should choose non-wheat-derived forms. As with any autophagy-promoting compound, those undergoing cancer treatment should consult their physician before supplementing.
