What is spermidine?
Spermidine, first isolated from semen or sperm, is a water-soluble polyamine ingredient that occurs naturally in all tissues of our human bodies and is also found in many other organisms like animals, plants, and typical dietary foods.

Spermidine is a small molecule with a molecular weight of 145.25 and a unique CAS Registry Number of 124-20-9. It’s stable at room temperature. The color of Spermidine-rich wheat germ extract is white to yellowish powder. Spermidine is also available in the chloride form as spermidine trihydrochloride or spermidine 3 HCL (CAS 334-50-9).
What is the difference between spermine and spermidine?
Both spermine and spermidine are polyamines involved in cellular metabolism. Popular polyamines include agmatine (AGM), putrescine (PUT), cadaverine (CAD), spermine (SPM), and spermidine (SPD). Spermine is a crystalline powder compound related to spermidine but is not the same.
Spermidine is a precursor to other polyamines, like spermine and thermospermine. The chemical name of spermidine is N-(3-aminopropyl) butane-1,4-diamine, while the CAS number of spermine is 71-44-3 (free base) and 306-67-2 (tetrahydrochloride).
Spermidine sources
There are two main ways to obtain bulk spermidine: one is from natural foods, and the other is from chemical synthesis.
There are several foods high in spermidine, such as wheat germ extract, fruits, grapefruit, yeast, mushrooms, meat, soybeans, cheese, Japanese Natto (fermented soybeans), green peas, rice bran, cheddar, etc. That’s why the Mediterranean diet is so popular since it has a high polyamine content in it. Below is the amount of spermidine content in foods from Wikipedia:
