This gut microbe may help keep you strong as you agehttps://www.sciencedaily.com/releases/2026/08/260820202904.htm
Scientists have linked a specific gut bacterium, Roseburia inulinivorans, to stronger muscles in both humans and mice. Older adults who carried it had 29% greater handgrip strength, while treated mice gained about 30% more grip strength and developed larger, more fast-twitch muscle fibers. The bacterium was also less common in older people. Researchers say it could eventually become a probiotic candidate for helping combat age-related muscle loss.
