Spermidine is a fascinating compound. And not until recently have researchers been able to better understand it.
We now know that spermidine is a unique, naturally occurring molecule, part of a group of molecules known as polyamines. Polyamines interact with our cells to perform various critical metabolic functions.
Spermidine is found in all plants and animals and in nearly every cell of your body. In our bodies, it can come from ingested food—synthesized in the gut microbiome or synthesized in cells.
