Autophagy plus NAD+.

Spermidine is a compound (also found in foods like wheat germ and aged cheese) that may switch on autophagy, the cell's recycling and clean-up process, while NMN raises NAD+ for repair and energy, so the two target distinct longevity pathways.

A common longevity pairing, though human outcome data is limited. Spermidine can be obtained partly from diet, the evidence base is still building, and it is wise to keep expectations measured and check with a doctor before adding either if you take medication.
