The systematic review and meta-analysis found that grape products had no significant effect on liver enzymes in adults. However, due to the limited number of studies included, further research is needed to evaluate the potential of grape products as a complementary treatment for improving liver enzymes.
Objective: This systematic review and meta-analysis were aimed to determine the effects of grape products on liver enzymes in adults. Methods: Databases including PubMed/Medline, Cochrane Library, ISI Web of Science, and Scopus were searched up to February 2021. Randomized clinical trials (RCTs) investigating the effect of grape products on serum concentrations of liver enzymes were included. Data were pooled using the random-effects model and weighted mean difference (WMD) was considered as the summary effect size. Results: Eight RCTs enrolling 291 participants met the inclusion criteria for this meta-analysis. The overall effect illustrated no significant change in serum levels of alanine aminotransferase (ALT) (WMD: 2.04; 95 % CI: 5.50 to 1.42; P = 0.24; I-2 = 72.5 %), and aspartate aminotransferase (AST) (WMD: 1.40; 95 % CI: 3.80 to 0.99; P = 0.25; I-2 = 76.0 %) in intervention group compared with the control group. Subgroup analyses revealed that the effect of grape products on ALT (WMD: 4.97; 95 % CI: 8.73 to 1.21; P = 0.01) and AST (WMD: 2.89; 95 % CI: 5.69 to 0.08; P = 0.04) levels was significant when the intervention period was equal or more than 12 weeks. Conclusion: Overall, grape products had no significant effect on liver enzymes in adults. However, due to the low number of included studies, these findings must be interpreted with great caution. Larger, well-designed RCTs are still needed to further evaluate the capacity of the grape products as a complementary treatment to improve liver enzymes.
