Arginine (Arg or R) is a non-essential amino acid. Arginine is the predecessor of nitric oxide and it is nitric oxide that helps to keep blood vessels dilated, allowing an adequate supply of oxygen to the heart. While in its early stages, some researchers have started using arginine in people who have congestive heart failure. Nitric oxide works when the inner layer of blood vessels (endothelium) of the arteries releases nitric oxide; this in turn relaxes those blood vessels, allowing flexibility and increased blood flow. Due to the natural effects of aging our bodies produce less nitric oxide and as a result it constricts the blood vessels and they lose their flexibility. This is a contributing factor to conditions such as hypertension and cardiovascular disease.
Arginine leads to nitric oxide and the nitric oxide keeps blood vessels dilated, which in turn leads to more oxygen traveling to the heart. For bodybuilders, nitric oxide dilates the blood vessels and causes the muscles to loosen up, allowing for a more effective workout and decreases the chances of injury, such as pulling or straining a muscle. It can easily be said that arginine is a preventative measure against Apart from these benefits, arginine is used in the prevention of colds, asthma, kidney failure and because it increases protein synthesis, which helps the body heal, it can be used after surgery.
Arginine is found mostly in various types of seeds, gelatins, soy protein, crustaceans and mollusks
