With catechin from green tea leaves
The most important representatives of catechins are epicatechin (EC), epicatechin gallate (ECG), epigallocatechin (EGC) and epigallocatechin gallate (EGCG). Most of the antioxidant effects of green tea are attributed to the catechins. In particular, the polyphenols naturally contained in some types of tea (especially epigallocatechin gallate, EGCG) are thought to be responsible for a preventative effect.
