Gut Bacteria Could Slow Age-Related Muscle Loss | Science News

A gut bacterium called Roseburia inulinivorans may be the secret to staying strong as you age. New research shows this microbe is linked to better muscle performance in both humans and mice, helping preserve fast-twitch muscle fibers crucial for power and mobility. Older adults with higher levels of this bacterium had significantly stronger grip strength, while younger adults with more of it also showed superior fitness. In mice, introducing R. inulinivorans boosted grip strength by 30% and increased fast-twitch muscle fibers. As this beneficial bacteria naturally declines with age, scientists are exploring it as a potential probiotic target to fight age-related muscle loss and help people stay active longer.
