Gut bacterium and its metabolite found to delay aging

A new study published in Nature Aging on Aug. 25 reports that a single gut bacterium—Bifidobacterium pseudocatenulatum (BP)—together with a small molecule it produces, 5-aminovaleric acid betaine (5-AVAB), can alleviate multiple hallmarks of aging and extend healthy lifespan in mice, opening a promising avenue toward healthier aging in humans.
