Gut & MicrobiomeGut Microbes May Unlock Exercise's Health Benefits as Drug-Like Molecules
Exercise transforms the gut microbiome, prompting bacteria to release metabolites that may replicate many of exercise's health benefits. Researchers from the University of Kentucky and the Buck Institute have coined the term 'microbial-derived exerkines' (MDEs) to describe these compounds. Candidates include pipecolic acid, succinate, short-chain fatty acids, indole-3-propionic acid, and 3-hydroxyphenylacetic acid. Each shows potential against conditions strongly linked to aging: inflammatory bowel disease, skeletal muscle atrophy, cancer, diabetes, cardiovascular disease, and Alzheimer's disease. The review argues that MDEs represent a largely untapped drug discovery pathway — one that could eventually deliver exercise-like therapeutic benefits to people unable to exercise adequately, or amplify benefits for those who do.
