Sumac powder supplementation is beneficial for the management of non-alcoholic fatty liver disease

This randomized double-blind placebo-controlled clinical trial was conducted to assess the effects of sumac powder supplementation on hepatic fibrosis and some metabolic markers in patients with non-alcoholic fatty liver disease (NAFLD).

To do so, 80 patients with NAFLD were randomized to receive either 2000 mg/d of sumac powder or placebo for 12 weeks. Outcome measures were hepatic fibrosis and liver enzymes (ALT and AST) as well as fasting blood sugar (FBS), serum insulin, HbA1c, HOMA-IR (insulin resistance index), QUICKI (insulin sensitivity index), malondialdehyde (MDA), and high sensitivity C-reactive protein (hs-CRP).

Results showed that, after 12 weeks, subjects in the sumac group showed a greater decrease in hepatic fibrosis and liver enzymes as well as FBS, serum insulin, HbA1c, HOMA-IR, MDA, and hs-CRP, compared to the placebo (p < 0.05); while the QUICKI was significantly higher in the sumac group at the end of intervention.

In conclusion, sumac powder along with a low-calorie diet for 12 weeks was beneficial for the management of NAFLD.
