Resveratrol (Commonly misspelled as reservatrol) is a polyphonic bioflavonoid compound with antioxidant properties most commonly found in grapes and wine, and it is believed to be the main ingredient responsible for some of wine’s health benefits. Resveratrol is commonly taken as supplement for a number of benefits including supporting overall health and healthy aging. There is some evidence Resveratrol may support cognitive function by supporting cerebral flow, but more research in this area is needed. Double Wood's Resveratrol is Vegan Safe, Manufactured in the USA, Non-Gmo, and Gluten Free. It contains 120 capsules and each serving is two 250mg capsules (500mg). This is enough Resveratrol to last a full two months if taken daily.
