after some research about nitric oxide I have found some interesting things. It is actually called Nitrogen monoxide. Nitric Oxide is actually a gas that the body uses. This is formed by breaking down arginine which is an amino acid. Nitric Oxide is a way for the body to stay active with cells within. This increases blood flow which brings more nutrients to the muscles as people work out. I had no idea that Nitric Oxide was so important for the body.
