Product Information
Grape seed extract is made from grape seeds, largely recovered from wine and juice production. It is valued for proanthocyanidins, also called OPCs (oligomeric proanthocyanidins), a class of polyphenols. The catalog lists grades at 45% and minimum 95% proanthocyanidins, a grade at 90% polyphenols with 25% monomers, and 4:1 and 5:1 ratio extracts. The powder is reddish brown with a strongly astringent taste, so it is usually encapsulated or tableted rather than used in unflavored drinks.
