Olympian Labs Grape Seed Extract contains 95% Oligomeric Proanthocyanidin B2-3'-O-gallate. Oligomeric Procyanidins are a more potent anti-oxidant than those from pine bark. Pycnogenols is a chemical term used to distinguish the polyphenolic calls of bioflavonoids which contain Flavin-3-oils from the simpler bioflavonoids. These Pycnogenols are also called Oligomeric Procyanidins. Both these terms refer to condensed structure of the Flavonol molecule.
Olympian Labs Grape Seed Extract, through a low temperature extraction method, is completely water soluble and free of dangerous solvents and food coloring additives. Water solubility means optimum bioavailability.
