Aim: The aim of this study was to determine the efficacy of a 6-month intramuscular vitamin D supplementation in improving the liver parameters in adult patients with non-alcoholic fatty liver disease (NAFLD).
Background: The association between vitamin D level and NAFLD has not been determined.
Methods: A single-blinded non-randomized controlled trial was conducted in 80 NAFLD patients assigned to receive a monthly single intramuscular dose of 200,000 IU cholecalciferol/vitamin D3 (n= 40), or placebo (n= 40) for six months.
