L-arginine (or arginine) is a type of amino acid, and as we know, amino acids are the "building blocks" of proteins. We obtain it from our diets, especially animal sources of protein foods, including beef and other types of red meat, poultry, fish, eggs, and dairy products.L-arginine HCL is the hydrochloride salt of L-arginine, a non-essential amino acid that is a component in many proteins and is a central part of the urea cycle, a process which allows the body to dispose of excess nitrogen.L-arginine supplements provide support for healthy metabolic and immune system function.
In addition to occurring naturally in "complete proteins" that supply all the essential amino acids we need, L-arginine is also created in laboratory settings so it can be used to make supplements tha heart health, exercise performance, mental capabilities and much more.
