L-Arginine is an essential amino acid in stress situations and a precursor for the formation of nitric oxide: it helps to cause the relaxation of blood vessels and is involved in the processes of transport, storage and excretion of nitrogen. There are several scientific studies that explain the benefits of supplementation with L-Arginine. Among them, it is worth noting that its intake helps improve wound healing by favoring cell replication and the immune response1 and that, associated with a weight training program, its oral administration enhances the stimuli of exercise at the level of skeletal muscles, providing greater strength and muscle mass. Others claim that this substance stimulates the secretion of growth hormone from the pituitary gland; which is one of the precursors of creatine; and that it is essential for the production of urea (necessary for the elimination of toxic ammonia from the body). In the formulation of L-Arginine 2000 Vitobest® uses L-Arginine from Ajinomoto®, the renowned Japanese brand with more than 100 years of experience that only uses amino acids isolated by fermentation; and vitamin C (Quali®-C) (DSM®), which acts as an important antioxidant.
