Grape Seed Extract to Improve Liver Function in Patients with Nonalcoholic Fatty Liver Change

Background/Aim:

Therapeutic interventions in nonalcoholic fatty liver disease are limited, while antioxidative materials have shown benefi ts in animal models. This study aimed to evaluate grape seed extract as an anti-oxidative material in this process. Therapeutic effects of grape seed extract were evaluated in comparison to vitamin C in a double-blind setting.

Materials and Methods:

Fifteen patients were enrolled in each group. Liver function tests were done; also, grade of steatosis and pattern of echogenicity of the liver were determined. Patients were followed up by the same evaluation repeated in first, second and third months.

Results:

Mean age ± standard deviation was 43.2 ± 10.3 years. Grape seed extract (GSE) significantly improved the grade of fatty liver change; and resulted in significant decrease in alanine aminotransferase in patients receiving the concentrate compared to those receiving vitamin C independently, from the initial grade of steatosis.

Conclusions:

This study describes the beneficial effect of using grape seed extract for three months in patients with nonalcoholic fatty liver disease. These results may improve with a longer period of follow-up.
