The aim of this study was to evaluate if Olife® consumption in patients with NAFLD could improve fatty liver grade and related metabolic and inflammatory parameters. Eighty-two Caucasian patients aged 18 of both sexes diagnosed with NAFLD, according to practice guidelines, were enrolled in a single-center, double-blind, open label, randomized, controlled study. Patients were randomized to follow a standardized Diet or a standardized Diet + Olife® for 3 months. No changes in BMI, circumference, FPG, TC, LDL-C, HDL-C and Tg were observed with either treatment. In the group of patients receiving Diet + Olife®, a significant decrease in hs-CRP and TNF- as well as an increase in ADN (p < 0.05 compared to Baseline and Diet) was observed, respectively. Transaminases and -GT were significantly reduced (p < 0.05 vs Baseline and Diet) in Diet + Olife® group compared to Diet group, respectively. In addition, AST/ALT ratio and HIS were significantly lower (p < 0.05 vs Baseline and Diet) in the Diet + Olife® group compared to Diet group, respectively. All patients showed signs of hepatic steatosis improvement or disappearance. In conclusion Olife® added to Diet ameliorates hepatic parameters and echography grading, and manages to reduce inflammatory parameters during the 3 months of study. https://pubs.sciepub.com/ajmsm/13/1/2/ajmsm-13-1-2.pdf food supplement oleuropein elenolic acid rutin hydroxytyrosol tyrosol hepatic steatosis
