Extract From Grape Seeds Proves a Powerful Antioxidant

The seeds and skins of grapes are exceptionally rich in proanthocyanidins, members of the family of phytochemicals called flavonoids. Proanthocyanidins are particularly powerful antioxidants when they are bound together. In their bound form, they have come to be known as oligomeric proanthocyanidin complexes, or OPC’s. A French biochemist patented a process for extracting these compounds from pine bark in 1951, then from grape seeds in 1970.
