Green Tea infusions are safe but the supplements can be hazardous to your liver

Taking high doses of supplements containing green tea extracts may be associated with liver damage, according to a new research from the European Food Safety Authority.Tea infusions as used for brewed tea, are considered safe. 

Instant tea drinkers are also fine as they contain lower levels of the antioxidants naturally present in green tea, Parma based EFSA said. Consuming too many of these antioxidants can be harmful, which is why the amount contained in supplements can have a harmful effect on liver.
