Grape seed extracts are industrial derivatives from whole grape seeds that have a great
concentration of vitamin E, flavonoids, linoleic acid and phenolic OPCs. The typical
commercial opportunity of extracting grape seed constituents has been for chemicals
known as polyphenols having antioxidant activity in vitro.
Grape seed extract consists of some of the most powerful antioxidants known. These
compounds are known as proanthocyanidins (OPC's). Grape seed extract helps support
cholesterol levels already within a normal range and the blood vessels. OPC's are
powerful antioxidants that can help reduce free radical damage. Grape seed extract
helps mop up free radicals that may cause damage to healthy tissue. OPC's can help
regenerate oxidized vitamin C and vitamin E providing an extended antioxidant value
to these molecules.
