L- Arginine isa α-amino acid that is employed in the biosynthesis of proteins. It is relevant for heart as well as blood vessel conditions including high blood pressure, congestive heart failure (CHF), chest pain and coronary artery disease.It makes nitric oxide in the body that relaxes the blood vessels and may benefit certain health conditions. As a pioneer to nitrogen oxide, it has a vital prominence for hair growth. The vasodilatory effect of L- Arginine boosts hair growth as the nitrogen oxide created from arginine unlocks the potassium canals of the cells. The blood source to the hair root is then recovered, which in turn excites hair growth.
