Spermidine - I am looking for a natural source of spermidine. Some say it is in grapefruit - but others say that is a myth and that the best source is Wheat Bran.
Wheat bran, it is claimed, has a whopping 243 mg/kg - that still sounds like a trace amount. Also, this is from a vegetarian source, and I do not know if it is well absorbed.
Spermidine aids in autophagy, from a different, more powerful angle that trehalose. It also prevents balding.
Obviously, wheat is an avoid for an O. Do you guys know if Oat Bran or Rice Bran have any Spermidine?
