Based on the Nobel Prize winning medical breakthrough of Dr. Louis Ignarro we present to you the MIRACLE MOLECULE “Nitric Oxide.” In the body Arginine converts to Nitric Oxide. Nitric Oxide helps relax blood vessels and improve circulation. Evidence also shows that Arginine may help increase blood flow in the arteries. This improved blood flow may help improve chest pain, clogged arteries and coronary artery disease. Because of the relaxed arteries and added blood flow there may be benefits which assist in erectile dysfunction. Other possible health benefits may include lowering of blood pressure and cholesterol.
