Natural Factors Resveratrol Concentrate 60 vcaps
Natural Factors ResveratrolRich Super Strength Resveratrol provides a high potency of 250 mg of trans-resveratrol in each 500 mg vegetarian capsule. The resveratrol is extracted from the skins of red grapes (Vitis vinifera), grown in the Okanagan Valley of British Columbia, and from Japanese knotweed (Polygonum cuspidatum). The knotweed is highly purified to remove 99% of the emodin, a natural substance that can act as a laxative in some sensitive people. Knotweed is commonly used in traditional medicines for the liver and heart.
