ApoLife 48 Phytospermidine 60 capsulesSpermidine is a biogenic polyamine found in all living organisms. Spermidine is a natural component of our cells, which our body produces in larger or smaller amounts depending on the metabolic situation. Humans produce about a third of our spermidine level themselves, the rest is ingested through food. The body's own spermidine production decreases with age, so that the amount of spermidine to be supplied from outside becomes increasingly important.
