This book describes the role of nitric oxide in health and disease. Nitric oxide is one of the most important molecules produced by humans and is considered the "Holy Grail" in cardiovascular medicine. Loss of nitric oxide production is what leads to chronic disease. Without healthy NO (Nitric Oxide) levels you cannot be healthy and prevent the diseases of aging. Nitric oxide is the secret to anti-aging. This book reveals the latest scientific and medical information so that readers can understand the importance of nitric oxide for optimal health. This eye-opening book teaches how the body makes NO, what goes wrong in people that can't make NO, and perhaps most importantly, how to restore production of this "miracle molecule".
