IMMUNE SYSTEM SUPPORT AND MANY OTHER BENEFITS. l-Arginine is most well-known for its use in cardiovascular support. Its other critical functions include assisting in wound healing, helping remove excess toxic ammonia from the body, supporting immune function, and promoting the secretion of several hormones, including glucagons, insulin, and growth hormone. It plays an important role in muscle metabolism by working to transport, store and excrete nitrogen.

CARDIOVASCULAR SUPPORT. l-Arginine is required to synthesize nitric oxide, which is produced by all tissues of the body. Nitric oxide regulates smooth muscle contraction, allowing blood vessels to relax and support blood flow. By supporting blood vessel dilation, l-arginine may play a role in supporting healthy circulation.

A GREAT SUPPLEMENT FOR A VARIETY OF PEOPLE. Many benefit from it, and it is also popular with athletes. l-Arginine is a key nutrient in the energy-generating Krebs cycle, where it participates in the detoxification of ammonia from the liver. Ammonia is a toxic byproduct of energy metabolism. It is converted to urea and eliminated from the body. Any l-arginine not converted to urea enters general circulation, where it is distributed to various tissues and metabolized for other uses such as protein synthesis.
