L-arginine is one of the 20 amino acids that build upprotein. L-arginine is one of the non-essential amino acids, meaning it can besynthesisedin 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 easilyrecognised. 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 thisreasonL-arginine helps in stimulating and maintainingerection. Men with erectile dysfunction benefit especially from the intake of L-arginine rich foods or l-arginine supplement.
Arginine is a part of ornithine, which hastremendouseffect ofphysiometry. L-arginine has been used for erectile dysfunction. Like the drug Weilinafil citrate (Viagra), L-arginine is thought to enhance the action of nitric oxide, which relaxes muscles surrounding blood vessels supplying the penis. As a result, blood vessels in the penis dilate, increasing blood flow, which helps maintain an erection. The difference in how they work is that Viagra blocks an enzyme called PDE5 which destroys nitric oxide and L-arginine is used to make nitric oxide.
