Gut microbiota metabolism of branched-chain amino acids and their metabolites can improve the physiological function of aging mice
The metabolism of branched-chain amino acids by gut microbiota can improve overall health and may reverse aging. In this study, we investigated Parabacteroides merdae, a gut microbe that is known to catabolise branched-chain amino acids (BCAAs). Three metabolites of BCAAs isovalerate, 2-methylbutyrate, and isobutyrate were used to treat D-gal induced aging mice. The results showed that these treatments could delay aging in mice by providing health benefits in reducing oxidative stress and...
