L-Arginine - 90 capsules
Food supplement with L-arginine.
Arginine is an amino acid produced in the pituitary gland. This means arginine is not an essential nutrient, but during heavy exertion, your body may not be able to produce it in adequate amounts.
Therefore, arginine intake as a nutritional supplement may be necessary (it is conditionally essential).
Arginine plays a very important role in the synthesis of nitric oxide, also known as nitrogen monoxide or NO.
