Spermidine

Coming later

Often sold from wheat germ or from synthetic or fermentation routes. Not in the directory yet.

Spermidine is a polyamine. Commercial articles include wheat-germ extracts and material produced by chemical synthesis or fermentation. Those routes are not interchangeable.

Fermentation and synthetic production are outside the current scope. This page does not approve a spermidine ingredient.
