L-Arginine 500 mg (Item #738)

L-Arginine is one of the amino acids produced in the human body by the digestion, or hydrolysis, of proteins. Because it is produced in the body, it is referred to as "nonessential," meaning that humans do not need to ingest it through food or supplements. Because L-Arginine is naturally converted into nitric oxide, a blood vessel dilator, by the human body, researchers have conducted preliminary studies to determine the effectiveness in using it as a supplement for supporting cardiovascular health. Other studies indicate that L-Arginine promotes immune health and supports the liver. Athletes supplement with L-Arginine for its benefits in building lean muscle mass and supporting blood flow while performing strenuous exercise.
