100 mg standardized grape seed extract Rich in protective polyphenols & OPCs

Grape Seed Extract delivers concentrated levels of our unique standardized extract. Grape seed has long been viewed as one of nature's most abundant sources of protective compounds called polyphenols and our Grape Seed Extract is standardized to provide a remarkable concentration of 80% polyphenols including the highly protective and desirable OPCs (oligomeric proanthocyanidins) that neutralize a wide variety of damaging free radicals in the body. Grape seed extract's protective benefits extend throughout the body, but it has long been recognized for its healthy support of the circulatory system; including the hard-working blood vessels and delicate capillaries that nourish our legs, skin, eyes and other vital organs. Grape seed is one of Mother Nature's richest sources of anti-oxidants and our unique Grape Seed Extract now concentrates those protective benefits to previously unavailable levels.

Contains no additives or common allergens Contains no milk, soy, yeast, corn, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
