L-arginine is one of the 20 amino acids that build up protein. L-arginine is one of the non-essential amino acids, meaning it can be synthesised in the body.
L-arginine is a precursor of nitric oxide and other metabolites. It is an important component of collagen, enzymes and hormones, skin and connective tissues. L-arginine plays important roles in the synthesis of various protein molecules; creatine and insulin being the most easily recognised
It may have antioxidant property and reduces accumulation of compounds such as ammonia and plasma lactate, by-products of physical exercise. It also inhibits platelet aggregation and has also been known to decrease blood pressure.
When consumed, L-arginine is converted to nitric oxide which aids in the relaxation of blood vessels. The effect is better blood circulation in the body and especially in the extremities; specifically the genitalia. For this reason L-arginine helps in stimulating and maintaining erection. Men with erectile dysfunction benefit especially from the intake of L-arginine rich foods or l-arginine supplement.
