L-arginine is an amino acid naturally found in red meat, poultry, fish, and dairy. It is necessary for making proteins and is commonly used for circulation.
L-arginine is an amino acid that helps the body build protein. Your, body usually makes all the L-arginine it needs. L-arginine is also found in most protein-rich foods, including fish, red meat, poultry, soy, whole grains, beans and dairy products.

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. It can be made in a lab and used in supplements.

Uses

L-arginine for chest pain and various blow flow issues, erectile dysfunction, high blood pressure during pregnancy, and a serious disease in premature infants called necrotizing enterocolitis (NEC).

• Studies suggest that L-arginine might decrease symptoms and improve quality of life in people with a mild to severe form of this type of chest pain.
• High blood pressure (hypertension).Some research has shown that oral L-arginine can lower blood pressure in healthy people, people with mild blood pressure elevation and diabetes, and in people with a type of high blood pressure that affects the arteries in the lungs and the right side of the heart (pulmonary hypertension). Infusions of L-arginine also appear to lower blood pressure in people with hypertension.
• High blood pressure during pregnancy.Some studies show that L-arginine infusions may lower blood pressure in pregnant women who develop high blood pressure.
• Peripheral arterial disease (PAD).When taken orally or by infusion for a short period of time, L-arginine may improve symptoms and blood flow in people with this circulatory condition.
