Spermidine: a physiological autophagy inducer acting as an anti-aging vitamin in humans?

Autophagy. 2019 Jan;15(1):165-168. doi: 10.1080/15548627.2018.1530929. Epub 2018 Oct 11.

Abstract

Spermidine is a natural polyamine that stimulates cytoprotective macroautophagy/autophagy. External supplementation of spermidine extends lifespan and health span across species, including in yeast, nematodes, flies and mice. In humans, spermidine levels decline with aging, and a possible connection between reduced endogenous spermidine concentrations and age-related deterioration has been suggested. Recent epidemiological data support this notion, showing that an increased uptake of this polyamine with spermidine-rich food diminishes overall mortality associated with cardiovascular diseases and cancer. Here, we discuss nutritional and other possible routes to counteract the age-mediated decline of spermidine levels.

Keywords: Autophagy; cancer; cardiovascular diseases; health span extension; longevity.
