Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease. It is characterized by a variety of pathologies, ranging from benign fatty liver to extensive fibrosis and even hepatocellular cancer. Among the several potential risk factors, insulin resistance and increased oxidative stress are the most important. Vitamin E is an antioxidant with a potential to be used as a treatment for NAFLD. Therefore, we carried out a structured systematic review of all RCTs conducted between 2010 and January 2020. After screening, eight RCTs were included. Our systematic review showed that vitamin E has clinical utility in improving biochemical (ALT and AST levels) and histological abnormalities in NAFLD (hepatic steatosis and lobular inflammation). However, vitamin E does not seem to have significant effects on liver fibrosis. Still, vitamin E has the potential to be used as an adjuvant for the treatment of NAFLD, and its use in clinical practice should be advocated.
