The number #1 killer is Heart Attacks, Strokes and cardiovascular complications. The silent killer is HBP (High Blood Pressure) that can result in Brain strokes. The human body has over 60,000 miles of veins. Blood vessels dilate because the endothelial cells in arteries produce a molecule that signals to the surrounding vascular muscle cells "telling" them to relax. Nitric Oxide (NO), a gas comprised of one nitrogen molecule and one oxygen molecule - commonly found in our atmosphere. NO is your body's own built-in, natural protection against heart disease. No is continually working sending out signals to help relax your vascular muscles. Unfortunately, most adults over 40 don't produce enough in order to achieve optimal health. Now you can help your body make NO naturally.
