BioVin is a full spectrum grape extract made from whole red wine grapes. BioVin is locally produced from premium quality grapes grown in southern France, using only water and ethanol as solvents. BioVin supplies OPCs from grape seeds, plus anthocyanins and other flavonoids found in grape skins know as "red wine polyphenols." BioVin also provides resvertrol, a beneficial antioxidant photochemical found only in grape skins. The whole grape constituents in BioVin support the body's antioxidant defenses by counteracting the effects of free radicals.
