What is EGCG?

OPCs typically consist of four chemically similar molecules, each having varying degrees of antioxidant ability. The least potent is epicatechin (EC), followed by epigallocatechin (EGC), epicatechin gallate (ECG), and finally, epigallocatechin gallate (EGCG), the most potent of the four. Not all OPCs contain EGCG, so it is important to look for EGCG content in OPC products.

While pine bark and grape seed are the preferred source of OPC, it has recently been proven that green tea contains more than either one.  However, more of one form of OPC does not necessarily mean better results. ECs, EGCs, and ECGs provide unique health benefits as well.

As with any supplement, it is important to read up on and learn the antioxidant properties, as well as the EGCG content of certain products you are considering. Be sure to consider what health benefits you are striving to achieve before choosing the dietary supplement that is right for you. Remember that, although EGCG is the most potent of all OPC antioxidant molecules, ECs, EGCs, and ECGs are also quite beneficial.  The benefits of ECGC 's are quite stong!
