L-arginine is an amino acid. It is necessary for the body to make proteins. L-arginine is found in red meat, poultry, fish, and dairy products.
L-arginine is used for heart and blood vessel conditions. Some people use L-arginine for blood pressure, improving athletic performance, boosting the immune system, and preventing inflammation of the digestive tract.
How does it work?
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.
Possibly Effective For:
Blood Pressure: There is early evidence that taking L-arginine by mouth can reduce blood pressure.
Inflammation of the Digestive Tract: Using L-arginine seems to prevent inflammation of the digestive tract and people report feeling soothed.
Blood Flow: L-arginine increases blood flow by converting into nitric oxide and causing the blood vessels to open for improved flow.
