L-arginine is an essential amino acid. Free base means that it is not bonded and is a free form amino acid. It has been shown to lower blood pressure and promote wound healing. Athletes have also found L-Arginine to be beneficial for muscle recovery.

L-arginine is required for the body to synthesise nitric oxide, which enables the arterial system to retain its youthful elasticity, thus alleviating hypertension in some people. Nitric oxide also helps to produce endothelial relaxation factor, which is needed by the arterial system to expand and contract with each heartbeat. The inability of arteries to expand and contract is a major cause of hypertension associated with ageing.

Surgical or traumatic injury greatly increases the body’s need for L-arginine, a key building block to repair damaged tissue and bone.
