Magnesium supports healthy cellular electrolyte function and vascular smooth muscle cells. The importance of magnesium intake was demonstrated in the 10 year follow-up of the Womens Health Study, where higher intakes of dietary magnesium were associated with maintaining healthy vascular relaxation. Both hawthorn and olive leaf have a long history of traditional use for maintaining cardiovascular health and have supported vascular function in studies. Patent pending MegaNatural-BP supports healthy blood vessel relaxation in volunteers, as demonstrated in a study conducted at the University of California, Davis. MegaNatural-BP grape seed is unique in that the extraction process maximizes the concentration of monomeric and oligomeric procyanidins and minimizes the concentration of polymeric procyanidins. Pomegranate, standardized to contain 40% punicosides, offers the antioxidant and vascular benefits associated with pomegranate juice. A recent double blind, placebo controlled trial in Israel suggests that the carotenoid lycopene from tomato extract provides powerful vascular antioxidant protection and healthy blood vessel relaxation support. Polyphenols from cocoa powder extract support healthy endothelial function and vasodilation. Studies using dark chocolate have reported positive effects with daily intakes of 75-100 milligrams of flavonols.Pure Encapsulations recommends 4 capsules daily,in divided doses, with meals.
