New Roots Herbal Grapeseed Extract - 500 mg - Grape seed extract is a rich bioflavonoid which is used for fighting free radicals and maintaining capillary health. It is very similar to pine bark extract, with a high content of proanthocyanidins. Grape seed extract is used for its free radical–fighting capabilities, and for a variety of conditions related to capillary health and permeability. It is synergistic with vitamin C, which is more potent and absorbed more rapidly when used together with proanthocyanidins. Proanthocyanidins present in grape seeds are known to exert anti-inflammatory, antiarthritic, and antiallergic activities; to prevent skin aging; to scavenge oxygen free radicals; and to inhibit the damaging effects of UV radiation from sunlight.
