Emerging evidence indicates that the role of Grape Seed Extract (GSE) in support of cardiovascular health may extend beyond its important antioxidant functions.  Scientific studies have shown that the proprietary GSE found in NOWð Blood Pressure Health, MegaNaturalð-BPð contains flavonoids that can support healthy arterial function already within the healthy range through a number of mechanisms.  In fact, these studies suggest that MegaNaturalð-BPð can help maintain blood pressure already within the healthy range.  In addition, NOW has included standardized Hawthorn Extract as a synergist.  Hawthorn Extract provides powerful antioxidant flavonoids, including standardized Vitexin that, along with other components in Hawthorn, have also been found to support healthy range blood flow and healthy range blood pressure.*
