Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Catechins, a class of polyphenolic compounds found predominantly in green tea, have been investigated for their potential benefits in treating non-alcoholic fatty liver disease (NAFLD). The primary catechin of interest is epigallocatechin gallate (EGCG). Several preclinical studies (in vitro and animal models) and a limited number of human clinical trials have explored the effects of catechins on hepatic fat accumulation, oxidative stress, and inflammation—key features of fatty liver disease.

A meta-analysis of randomized controlled trials (RCTs) published in 2020 (Phytotherapy Research, PMID: 32702280) showed that green tea or green tea extract supplementation resulted in modest reductions in liver enzyme levels (ALT and AST), which are surrogate markers for liver injury. A few clinical trials (J Nutr 2009; Int J Mol Med 2013) have reported improvements in hepatic steatosis and metabolic parameters among NAFLD patients taking green tea extracts rich in catechins. However, these studies often suffer from small sample sizes, short durations, and varying dosages, which limit the strength of their conclusions.

While preclinical evidence is promising and several mechanisms—such as improved lipid metabolism, reduced oxidative stress, and anti-inflammatory effects—have been proposed, the overall clinical evidence remains preliminary. Major liver societies do not currently recommend catechins as a standard therapy for NAFLD. Thus, catechins may offer benefit, but their efficacy is not yet strongly established.
