What is L-arginine?

L-arginine is a chemical building block called “an amino acid.” It is obtained from thediet and is necessary for the body to make proteins. L-arginine is found in red meat, poultry, fish, and dairy products. It can also be made in a laboratory and used as medicine.



L-arginine is used for heart and blood vessel conditions including congestive heart failure (CHF), chest painhigh blood pressure, and coronary artery disease. L-arginine is also used for recurrent pain in the legs due to blocked arteries (intermittent claudication), decreased mental capacity in the elderly (seniledementia), erectile dysfunction (ED), and male infertility.

L-arginine is converted in the body into a chemical called nitric oxide. Nitric oxide causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body.
