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 Women’s 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. CranLoad delivers a unique cranberry and grape seed blend developed as part of an extensive research program with the Institute of Nutrition and Functional Foods (INAF) and Universite Laval in Quebec, Canada. In addition to possessing antioxidant activity, these compounds offer specific vascular support mechanisms that are associated with enhanced endothelial function. In a pilot trial involving elite athletes, CranLoad provided statistically significant support for healthy flow-mediated dilation (FMD) at rest, an effect similar to arginine administration.
