β-Muricholic acid (β-MCA) is a murine-specific primary bile acid.[1],[2] Dietary administration of β-MCA reduces HMG-CoA reductase activity in liver microsomes from mice fed a high cholesterol and cholic acid diet.[3] Dietary administration of β-MCA also dissolves 100% of gallstones in a gallstone-susceptible mouse model of diet-induced cholesterol gallstones.[4]
