Can a common spice boost liver health in fatty liver disease?
NCT ID NCT07768657
First seen Aug 17, 2026 · Last updated Aug 18, 2026 · Updated 1 time
Summary
This trial tests whether adding sumac spice to a calorie-restricted diet can improve liver function and metabolic health in adults with obesity and non-alcoholic fatty liver disease (NAFLD). About 100 participants aged 30-60 will be randomly assigned to take either a placebo or one of two doses of sumac daily for 12 weeks. Researchers will measure changes in liver enzymes, blood sugar, insulin resistance, cholesterol, and inflammation to see if sumac offers extra benefits beyond diet alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sumac (Rhus coriaria L.) supplement at 1.5 g/day or 3.0 g/day, combined with a calorie-restricted diet (1250-1300 kcal/day) for 12 weeks.
- What this could lead to
- If sumac proves effective, it could offer a natural, low-cost addition to diet plans for improving liver function and metabolic health in people with fatty liver disease.
- What could go wrong
- This is a small, early-stage trial, and results may not be conclusive. The benefits of sumac beyond calorie restriction alone are uncertain, and individual responses may vary.

Inclusion Criteria: * subjects were required to be obese adults aged 30 to 60 years with a Body Mass Index (BMI) of 30 kg/m2 * confirmed diagnosis of Non-Alcoholic Fatty Liver Disease (NAFLD) via abdominal ultrasonography. * Biochemically, participants met the criteria for elevated liver enzymes, defined as alanine aminotransferase (ALT) \> 56 U/L, aspartate aminotransferase (AST) \> 40 U/L, or alkaline phosphatase (ALP) \> 147 U/L. * They also exhibited impaired glycemic status with a fasting blood sugar (FBS) \> 130 mg/dL and a glycated hemoglobin (HbA1c) level between 6.0% and 8.0%, . * dyslipidemia characterized by total cholesterol \>200 mg/dL, triglycerides \>150 mg/dL low-density lipoprotein (LDL) \>100 mg/dL, or high-density lipoprotein (HDL) \< 40 mg/dL. * Finally, all selected individuals demonstrated a documented willingness to participate in a supervised, calorie-restricted dietary intervention. Exclusion Criteria: * individuals were excluded from the study if they presented with secondary causes of hepatic steatosis, including significant alcohol consumption, chronic viral hepatitis (B or C), * autoimmune hepatitis, or drug-induced liver injury. * Potential participants were also excluded if they had a history of advanced liver disease (cirrhosis or hepatocellular carcinoma), * severe renal or cardiovascular comorbidities, or were currently taking medications known to induce steatosis (such as systemic corticosteroids or amiodarone). .Pregnant or lactating women were likewise excluded from enrollment.
