An amino acid useful for angina, high blood pressure, congestive heart failure and heart health. L-arginine boosts nitric oxide levels, which causes blood vessel relaxation (vasodilation). L-arginine also triggers the body to make protein and has been studied for wound healing, bodybuilding, enhancement of sperm production and prevention of wasting in people with critical illnesses. L-arginine also stimulates the body to release growth hormone and may enhance sexual performance. Note: Studies indicate that people who have already had heart attacks should not use arginine as it may worsen their condition.
