Gut microbiota play a key role in polyphenol metabolism, participating in the breakdown of dietary components and producing various small molecule metabolites that affect human health. However, little is currently known about how gut microbes metabolize dietary compounds and produce bioactive metabolites. This study aims to use metabolomics to precisely identify food-derived metabolites in the blood to investigate whether probiotics (BLa80, LRa05) can enhance the breakdown of dietary components and improve their absorption and utilization in the human body.
