L-Arginine is an amino acid, which provides energy to all cells throughout the body. L-Arginine can naturally be found in red meat, poultry, fish and dairy products. When consumed in the body, L-Arginine changes into nitric oxide, a powerful neurotransmitter that may help blood vessels relax and improve circulation. By improving circulation, L-Arginine promotes faster work-out recovery from exercise, and improves the work capacity of active muscles. L-Arginine is also known as a growth-hormone releaser, which can lead to increased lean muscle mass, strength and power. L-Arginine also improves the process of clearing waste from your muscles, which may result in a reduced sense of fatigue.
