Polyphenols from Grape Seed Extract
This highly advanced product contains OPCs (oligomeric proanthocyanidins) derived exclusively from grape seeds. France is the leader in OPC applications for human health. Grape seed OPCs are much more popular in France than the pine bark source. The grape seed OPCs have been subjected to rigorous bioavailability studies using advanced isotope marking techniques. And perhaps another reason they are preferred in France can be explained by the fact that only the grape seed source contains gallic esters which have been described as the most active substances. The OPCs in this product are provided in a synergistic base of bioflavonoids.
