Arginine is a naturally occurring amino acid found within the body. Your body also receives arginine from various foods you may consume that are high in protein such as fish, poultry, red meat, grains, nuts, wheat germ, and dairy products. Arginine has been lauded for its known heart benefits. Within the body, arginine is converted to nitric oxide which acts as an agent to widen blood vessels, a vasodilator that improves blood flow and may improve many conditions. Common issues that arginine may improve are as follows: headaches caused by swelling of the vessels, artherosclerosis, chest pain, erectile dysfunction, heart disease, and vascular disease. In some patients arginine may help reduce blood pressure. Other possible uses centered around arginine's ability to cue the body to create protein include wound healing, increasing sperm production, and bodybuilding.
