what is the l-arginine hydrochloride
l-arginine hcl 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.
