Iterative Design Trial to Assess Dietary Supplements and Other Aging-targeted Therapies

Spermidine is a polyamine that forms naturally in plants, animals, and microorganisms as a byproduct of protein breakdown. While it's found in various foods, the highest concentrations are in wheat germ, soy, and fermented foods like cheese and miso (Madeo et al. 2018). Spermidine is known for its role in promoting autophagy, a cellular process that helps to clear damaged cells and improve overall cellular function (Eisenberg et al. 2009; Gabandé-Rodríguez, Gómez de Las Heras, and Mittelbrunn 2019). As a result, spermidine has recently attracted significant scientific interest for its potential to enhance lifespan and overall health in laboratory studies.
