L-arginine is one of the 20 most common natural amino acids in the human body. It is called semi-essential amino acid since our body learns to synthesize it only after birth.

While the L-arginine produced is usually enough for the body’s use, certain health states especially stress increase demand for the amino acid.

Stress, trauma, sepsis and aging are common factors that necessitate L-arginine supplementation to supplement the level of the amino acid synthesized in the body.

Arginine has an enormous effect on hair growth. As a precursor to nitrogen oxide, it is of vital importance for hair growth. The vasodilatory effect of arginine promotes hair growth as the nitrogen oxide generated from arginine opens the potassium channels of the cells.
