GPT and fatty liver disease: Carnosine supplementation improved neither fibroScan®-related parameters, including median stiffness (hepatic fibrosis), controlled attenuation parameter (CAP) score (hepatic steatosis), and interquartile range to median stiffness (reliability of hepatic stiffness) nor liver function tests, such as alanine transaminase (ALT), gamma-glutamyl transferase (GGT), and alkaline phosphatase (ALP) as compared with placebo.
