Notes
grade-b Notable Very High See all 5 studies
The decrease in liver enzymes associated with cholestasis is quite strong, and TUDCA is a reference drug for these effects
grade-b Notable Low See all 9 studies
There appears to be a notable decrease in both ALT and γ-GPT in persons with non-alcoholic fatty liver (NAFLD) which may exceed 50% when vitamin E is supplemented above 300mg for half a year; there does not appear to be any influence whatsoever in healthy controls.
grade-b Minor Moderate See all 16 studies
No significant influence on liver enzymes associated with curcumin supplementation in most people, however, a small reduction is more likely in people with elevated liver enzymes.
