L-Arginine is a nonessential amino acid, which means that in normal conditions it can be synthesised by the human body to meet its needs.
In case of poor nutrition or heavy physical activity, the body is no longer capable of producing enough Arginine, so a certain amount should be consumed via diet or supplements.

Being the only precursor of nitric oxide (NO) and an important precursor to Creatine, Arginine supplementation is common among athletes and bodybuilders.
