A Probiotic in Fermented Milk Protected Muscle in Mice by Reshaping Bile Acids
Graded Preliminary — mouse study of dexamethasone-induced muscle wasting with no sample size reported, still the effect has not been tested in people.
This early animal work hints gut bacteria may influence age-related muscle loss.
Certain probiotic strains changed the mix of bile acids in the gut, which flipped a signal that told muscle to stop breaking down protein. In mice with drug-induced muscle wasting, two Bifidobacterium strains preserved muscle mass and fiber size. The researchers also turned them into a fermented milk that tasted fine in testing. This is early animal work, so it says nothing yet about human muscle loss with age.
