EFSA has assessed the safety of green tea catechins from dietary sources, following concerns regarding their possible harmful effects on the liver. EFSA concluded that catechins from green tea infusions and similar drinks are generally safe. However, catechin doses at or above 800 mg/day may pose health concerns when taken as food supplements.
For green tea infusions, EFSA’s experts concluded that there is no indication of liver damage even after high consumption and that the few cases of liver damage reported in humans are likely due to rare and unpredictable reactions. Experts, therefore, considered catechins from green tea infusions brewed with hot water, and instant and ready-to-drink green tea beverages with similar catechin content, as generally safe.
