Inhibition of intestinal bile salt hydrolase (BSH) activity by compounds like theabrownin or riboflavin increases conjugated bile acids in the distal ileum, which inhibits intestinal FXR signaling and upregulates hepatic CYP7B1, thereby promoting the alternative bile acid pathway.

Consider incorporating Pu-erh tea or other sources of theabrownin into your diet. These compounds may inhibit bacterial enzymes in the gut, leading to a favorable shift in bile acid signaling that supports metabolic health.

oral administration of TB in mice suppressed the activity of intestinal bacterial BSH enzymes... accumulation of conjugated BAs in the distal ileum... inhibited intestinal FXR and downstream FGF15-FGFR4 signaling and thus, upregulated the BA synthesis genes... CYP7B1
