Epigallocatechin- gallate (EGCg) is the main catechin in green tea and provides many health benefits. High EGCg intake (>800 mg/day), either in pure form or in form of green tea extracts, especially consumed on an empty stomach can cause side effects such as liver inflammation. Therefore, the EFSA regulated EGCg in pure form as approved NOVEL FOOD (Novel Food Regulation EU 2017/2470) and EGCg containing green tea extracts in the EU regulation No. 2022/2340. Both regulations limit the daily dosage of EGCg and requires labelling warnings for EGCg.
