Arginine is a non-essential amino acid that is important to many different bodily processes. Arginine HCL is a form of arginine that combines the amino acid with a hydrogen chloride molecule and can be found in either powder or capsule form.
L-arginine is the only naturally occurring amino acid that produces nitric oxide. Nitric oxide is essential to the body for circulatory health. It helps with the elasticity of arterial walls and increases vasodilation, allowing for better blood flow.
Hydrogen chloride has a neutral PH so is combined with arginine to make the supplement more palatable and to enhance its absorption by the digestive system.
L-arginine is found in red meat, poultry, fish, and dairy products. It can also be used in dietary supplements such as dry blends, nutraceutical drinks, powdered sports beverages, protein shakes.
