The supplementation of 500 mg RSV for 12 weeks significantly decreased the alanine aminotransferase (ALT) concentration and hepatic steatosis in 50 NAFLD patients compared to the placebo (P < 0.05); however, no expected improvements in anthropometric measurements, insulin resistance (IR), lipid profile, and BP were observed (P > 0.05) [15]. This evidence concerns the gene GPT and fatty liver disease.
