What is L-Arginine used for?

L-Arginine is the active form of the amino acid Arginine and is necessary for the body to make proteins. The enzyme Nitric Oxide Synthase (NOS) uses L-Arginine to make Nitric Oxide (NO). NO causes blood vessels to open wider for improved blood flow. The enzyme Arginase uses L-Arginine to make Urea and Ornithine in a process that also disposes of excess ammonia in the body. Arginine is found in protein food sources like red meat, poultry, fish, and dairy products. 

Arginine stimulates the release of Growth Hormone, Insulin, and other substances in the body. Arginine is also used for the treatment of heart and blood vessel conditions including Congestive Heart Failure (CHF), chest pain, high blood pressure, and coronary artery disease.
