Green tea influences liver enzymes differently based on an individual's health status, reducing levels in patients with Nonalcoholic Fatty Liver Disease, but slightly increasing levels in healthy subjects.
The researchers initiated a comprehensive review and analysis of randomized clinical trials relating to green tea supplementation's effects on liver enzymes. This analysis included forms of green tea supplementation, such as catechin. The information to support this examination was sourced from four medical and health databases and included all trials examining the influence of green tea or its derivatives on specific liver enzymes, including Alanine Transaminase, Aspartate Aminotransferase, Alkaline Phosphatase, and Bilirubin. Altogether, fifteen trials were considered for inclusion in this research.
The study found that while the overall effect of green tea on liver enzymes was nonsignificant, further analysis showed that the impact of green tea on liver enzymes varies depending on an individual's health status. Notably, the use of green tea reduced liver enzyme levels in participants diagnosed with Nonalcoholic Fatty Liver Disease. However, in contrast, a small but statistically significant increase in liver enzyme levels was observed in healthy subjects. These findings suggest that the therapeutic potential of green tea may differ significantly based on an individual's health condition.
