Natural Factors GrapeSeedRich™ concentrate is a 100:1 concentrate guaranteed to contain a minimum of 95% polyphenols and 80% proanthocyanidins. Unlike some grape seed products, Natural Factors Grape Seed (Vitis vinifera) is not made from oven -or- sun-dried seeds. It is made exclusively from fresh, non-GMO grape seeds separated during juice production. This method produces a high ratio of the key polyphenols. The extraction process uses water and ultra filtration, not organic or alcohol solvents. The result is a 100:1 concentrate of pure, potent polyphenols. Polyphenols in grape seed are leucoanthocyanins or proanthocyanidins. These flavonoids help to strengthen blood vessels, increasing the tone and elasticity of capillary walls, enhance the effect of vitamin C and help to quench free radicals.*
