Frequently Asked Questions
Can I get spermidine from food?
Yes. Wheat germ (1.5mg/100g), aged cheese, mushrooms, and soy are rich sources. But supplementation ensures consistent dosing.
Spermidine vs fasting for autophagy?
Spermidine mimics fasting-induced autophagy. They work synergistically. Take spermidine A.M. then fast for best results.
Is it related to sperm?
The name comes from its discovery in sperm, but it has nothing to do with fertility. It is found in all living cells.
Spermidine vs rapamycin?
Spermidine is gentler with fewer side effects. Rapamycin is more potent but requires medical supervision. They target different pathways.
