Although non-alcoholic fatty liver disease (NAFLD) is the leading aetiology of liver disorders in the world, there is no proven treatment for NAFLD patients with normal or low BMI. The aim of this study was to evaluate the efficacy of synbiotics supplementation in NAFLD patients with normal or low BMI. In this randomised, double-blind, placebo-controlled, clinical trial, fifty patients with NAFLD were assigned to take either a synbiotic supplement or a placebo capsule for 28 weeks. Both groups were advised to follow a healthy lifestyle. At the end of the study, hepatic steatosis and fibrosis reduced in both groups; however, the mean reduction was significantly greater in the synbiotic group rather than in the placebo group (P<0·001). Furthermore, serum levels of fasting blood sugar, TAG and most of the inflammatory mediators reduced in the synbiotic group significantly compared with the placebo group (P<0·05). Our results provide evidence that synbiotic supplementation improves the main features of NAFLD in patients with normal and low BMI, at least partially through reduction in inflammatory indices. Further studies are needed to address the exact mechanism of action of these effects.
A two-arm randomized open labeled controlled clinical trial was conducted on 50 patients with non-alcoholic fatty liver disease (NAFLD). Participants were assigned to take either a lifestyle modification (LM), or LM +30 g/day brown milled flaxseed for 12 weeks. At the end of the study, body weight, liver enzymes, insulin resistance and hepatic fibrosis and steatosis decreased significantly in both groups (p< 0.05); however, this reduction was significantly greater in those who took flaxseed supplementation (p < 0.05). The significant mean differences were reached in hepatic markers between flaxseed and control group, respectively: ALT [-11.12 compared with -3.7 U/L; P< 0.001], AST [-8.29 compared with -4 U/L; p < 0.001], GGT [-15.7 compared with -2.62 U/L; p < 0.001], fibrosis score [-1.26 compared with -0.77 kPa; p = 0.013] and steatosis score [-47 compared with -15.45 dB/m; p = 0.022]. In conclusion, flaxseed supplementation plus lifestyle modification is more effective than lifestyle modification alone for NAFLD management.
Background:Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. The pathogenesis of this disease is closely associated with obesity and insulin resistance. Ginger can have hypolipidemic and antioxidant effects, and act as an insulinsensitizer.Objectives:The aim of this study was to evaluate the effects of ginger supplementation in NAFLD management.Patients and Methods:In a randomized, double-blind, placebo-controlled clinical trial, 44 patients with NAFLD were assigned to take either two grams per day of a ginger supplement or the identical placebo, for 12 weeks. In both groups, patients were advised to follow a modified diet and physical activity program. The metabolic parameters and indicators of liver damage were measured at study baseline and after the 12 week intervention.Results:Ginger supplementation resulted in a significant reduction in alanine aminotransferase, γ-glutamyl transferase, inflammatory cytokines, as well as the insulin resistance index and hepatic steatosis grade in comparison to the placebo. We did not find any significant effect of taking ginger supplements on hepatic fibrosis and aspartate aminotransferase.Conclusions:Twelve weeks of two grams of ginger supplementation showed beneficial effects on some NAFLD characteristics. Further studies are recommended to assess the long-term supplementation effects.
Background
The aim of the present study was to evaluate the effects of curcumin supplementation on inflammatory indices, and hepatic features in patients with non-alcoholic fatty liver disease (NAFLD).
Methods
Fifty patients with NAFLD were randomized to receive lifestyle modification advice plus either 1500 mg curcumin or the same amount of placebo for 12 weeks.
Results
Curcumin supplementation was associated with significant decrease in hepatic fibrosis (
p
< 0.001), and nuclear factor-kappa B activity (
p
< 0.05) as compared with the baseline. Hepatic steatosis and serum level of liver enzymes, and tumor necrosis-α (TNF-α) significantly reduced in both groups (
p
< 0.05). None of the changes were significantly different between two groups.
Conclusion
Our results indicated that curcumin supplementation plus lifestyle modification is not superior to lifestyle modification alone in amelioration of inflammation.

This study aimed to evaluate the effects of hesperidin on nonalcoholic fatty liver disease (NAFLD) characteristics. In this randomized, double-blind, controlled clinical trial, 50 NAFLD patients were supplemented with either 1-g hesperidin capsule or identical placebo capsule for 12 weeks. During the intervention, both groups were advised to follow healthy lifestyle habits including dietary and physical activity recommendations. At the end of the study, hesperidin supplementation, compared with placebo, was associated with a significant reduction in alanine aminotransferase (p = .005), γ-glutamyltransferase (p = .004), total cholesterol (p = .016), triglyceride (p = .049), hepatic steatosis (p = .041), high-sensitivity C-reactive protein (p = .029), tumor necrosis factor-α, and nuclear factor-κB (NF-κB). In conclusion, our results indicate that hesperidin supplementation accompanied with lifestyle modification is superior to lifestyle modification alone in management of NAFLD at least partially through inhibiting NF-κB activation and improving lipid profile. Further studies with higher dose of hesperidin are required to find the optimal dose.
