Why arginine is good for you

Arginine is a semi-essential amino acid which is required to ensure the liver, joints, muscles (including the heart muscle) and skin are kept healthy. Arginine strengthens the immune system, promotes male fertility and is involved in regulating many hormonal processes in the body (the pituitary gland, the pancreas and human growth hormone).

Arginine is a semi-essential amino acid because the body can usually produce enough arginine in normal circumstances, but if the body is under a great amount of physical stress or illness, then more arginine is required. In addition, new born babies cannot make their own arginine for the first few months of their life.
