Polyphenols are a very diverse and multi-functional group of active plant compounds (phytochemicals) with substantial health potential in many areas. OPCs (Oligomeric Proanthocyanidins) are a powerful subset of these phytochemicals which are present in diverse plant sources and found in the highest concentrations in grape seed and pine bark extract. They are 20 times stronger than Vitamin C and 50 times stronger than Vitamin E as an antioxidant, but this action as a direct antioxidant is not the most important of their potential benefits. Their ability to modulate intracellular signaling pathways throughout the body is one of their most important functions and is being heavily researched. In addition, through the activation of Nrf2, the “cellular master regulator,”they have diverse actions on metabolic, immune and cellular-protective pathways in the body and help to re-establish signaling pathways to aid in healthy cellular and tissue function.

The most valuable OPC ingredients known are extracts of French Maritime Pine Bark, Grape Seeds and Red Grapes (our Red Grape Extract does not come from wine and is never fermented). In addition, Bilberry extract (containing potent anthocyanins) and Citrus Bioflavonoids provide two more powerful plant-extracted polyphenols. that add even more power and protective properties. OProCyn has combined high-quality sources of all these ingredients into a synergistic combination and is isotonically delivered for better absorption… giving you unprecedented potency-per-dose in our OProCyn™ High Potency OPC Formula – making it the most powerful isotonic OPC supplement on the market today.

A Note on Quality: As we will describe later, the QUALITY of the OPCs you buy is everything! Only high quality and purity of OPC ingredients like those used in OProCyn can give you the amazing benefits of OPCs that everyone is talking about. The scientific literature is very clear on this point.
