Spermidine delays aging in humans

This is a preprint derived from other sources. If it holds up, it is useful information. There is no direct translation but a reasonable inference for diet and supplementation is that a typical diet might not want to supplement dietary sources (wheat germ, legumes, mushrooms, aged cheese, natto/tempeh, and other fermented foods) with more than 5 mg/day. Doublewood offers 5 mg capsules.
