The body is unable to produce sufficient amounts of arginine during periods of rapid growth, in case of trauma and in stressful situations. For this reason, studies have been carried out on the use of arginine as a nutritional supplement in the restoration of growth. Arginine plays an important role in the functioning of the cardiovascular system as the body uses arginine to produce NO (Nitric Oxide) which exerts a vasodilating effect, an important factor in maintaining healthy blood flow in the body. It is also required for optimal growth, taking part in the release of growth hormone while also contributing to the removal of ammonia (produced by nitrogen metabolism) from the body. Arginine is found in foods such as dairy products, meat, poultry, fish and nuts, but is generally present in low levels in fruits and vegetables. Lamberts ® L-Arginine is a pure, free-form amino acid ready to be absorbed by the body, without requiring its breakdown by digestive enzymes.
