L-Arganine – Arginine has excellent nitrogen retention ability, which is important for muscle protein synthesis and enhancing the immune system.

It is used widely in supplements associated with rejuvenation and anti-aging, since it is known to stimulate activity in the Thymus gland which is important, particularly for those recovering from illness and injury.

L-Arginine is also key in weight control and muscle retention. Arginine appears to increase HGH levels by blocking the secretions of growth hormone inhibitor Somatostatin.

L-Arginine may assist in stimulating the pancreas to release insulin, is a component of the pituitary hormone vasopressin and may assist in the release of growth hormones.
