Taking L-arginine as a supplement may increase blood flow and muscle growth. For some, it may also cause side effects, such as nausea or diarrhea. L-arginine is one of the amino acids the body needs to build muscle and heal wounds
When L-Arginine is converted into nitric oxide, it plays an important supporting role in cardiovascular health by supporting optimal circulation and inner blood vessel health by allowing oxygen, blood and nutrients to travel more efficiently throughout the body. The dilation of blood vessels created by nitric oxide not only promotes optimal circulation, but also plays an important role in cell division and healthy immune function.
