NOW® Grape Seed Extract is a highly concentrated natural extract with a minimum of 90% Polyphenols, including Oligomeric Proanthocyanidins (OPCs), which are the potent water-soluble free radical scavenging compounds found in Grape Seeds.*
A growing body of research indicates that Grape Seed OPCs may help to support the health of vascular, bone, kidney, brain and other tissues by supporting a healthy, balanced immune response to oxidative and metabolic stress.*
Natural color variation may occur in this product. This extra strength product has over four times the Grape Seed Extract (250 mg per capsule) as in our regular strength product (60 mg per capsule).
