These discoveries were laid down in my U.S. Patent (no 4,698,360) of Oct. 6 1987, 'Radical Scavenging Effect of Proanthocyanidins' . . . The tests showed that in this respect OPC from Grape seed has an advantage over OPC from Pine bark. OPC from grape seed contains the gallic esters of proanthocyanidins (in particular: Proanthocyanidin B2-3'-O-gallate). These proanthocyanidins -esters have been recently described as the most active substances in the battle against free radicals." October 1991 Martiliac, France (Procyanidines de France). Independent research by Dr Ricardo Da Silva showed "Proanthocyanidin B2-3'-O-gallate" available only in grape seed was found the most effective compound in trapping free radicals.

 Strength: Pycnogenol (Pine tree) has an OPC strength ranging from 80-85% compared with Grapeseed normally marketed at 90-95%. Be careful that the Grapeseed is 95%. A slight difference in favour of grapeseed. Research points toward the fact that proanthocyanidin 100% purity is non-mutagenic. Thus the range 90-95% for maximum benefit.
