Spermidine is a polyamine supplement. Like any supplement, it can interact with prescription medications, underlying conditions, and pregnancy or breastfeeding. Consult a qualified physician before starting any new supplement, including spermidine — especially if you are pregnant, nursing, under 18, over 65, have a chronic health condition, or take prescription medication.
