Recommended dosage, active amounts, other details
10-13mg daily has once been shown to improve liver regenesis rates in a clinically ill population, and may be the lowest estimate of an active oral dose. When looking at improving bile salt composition, a dose around 15-20mg/kg bodyweight TUDCA seems best according to one study.
Benefits have been seen at 1,750mg daily for muscle and liver insulin sensitivity, which is the highest dose used for treatment of fatty liver disease.
