Abstract in brief

  • The systematic review found that green tea and its extracts can pose liver toxicity risks, especially when consumed in concentrated forms or as large bolus doses, with the hepatotoxicity linked to certain catechins like EGCG.
  • Human studies confirmed that large, concentrated doses of green tea extract may cause liver adverse events, but regular brewed tea or food-based preparations generally do not pose this risk when consumed in typical amounts.
  • The review suggests safe intake levels of EGCG for adults, with 338mg per day as a limit for solid supplements and up to 704mg per day considered safe for tea drinks, based on toxicological and human safety data.]
