A lot of people have never heard of arginine, yet it is a chemical our bodies produce naturally. This amino acid is a building block that helps create proteins. It stimulates the release of insulin and gets rid of ammonia. Most importantly, the body uses arginine to make nitric oxide. Children need arginine to help them grow and develop. In adults, it helps improves blood flow, heals wounds, and repair damaged tissue. The good news is that arginine is found in many foods, so it is easy to increase your intake when your body needs more.


1. How Arginine Works

Also known as L-arginine, the amino acid converts into nitric oxide, a powerful neurotransmitter that causes blood vessels to widen and relax, improving circulation and blood flow. It also plays a major role in how the body disposes of waste. Arginine helps produce urea, the end product from the break down of proteins that forms urine.
