Doctor's Best Trans-Resveratrol 600, 600mg - 60 vcaps

Trans-Resveratrol 600 provides highly concentrated levels of trans-resveratrol from the root of the Japanese knotweed (Polygonum cuspidatum). Japanese knotweed provides one of the highest resveratrol concentrations found in nature. Resveratrol exists in both trans- and cis-forms. However, published research suggests that only the trans-form has valuable biological activity.
