What is it and what is it used for? Infisport ND4 Cross Up 50g Lemon is a semi-liquid gel formulated with different types of carbohydrates. It provides fast and long-lasting energy. It contains branched-chain amino acids (BCAAs), particularly L-leucine, which has an anti-catabolic and fatigue-reducing effect, delaying the onset of central fatigue. It also contains glutamine, which helps prevent overtraining and acts as an antioxidant by neutralizing ammonium radicals. This product is enriched with vitamins B and C, which have antioxidant properties and effects. These elements protect muscle fibers from the effects of free radicals generated during exercise. Vitamin B1 and magnesium facilitate the metabolism of carbohydrates into energy. It is a nutritional supplement that includes citrate and citric acid among its ingredients. These active ingredients are very effective in combating metabolic acidity. It is a gel that acts on all the physiological conditions of the body involved when undergoing intense exertion. During sports training, glycogen reserves in the muscles are depleted more rapidly. This is when metabolic acidity increases, and a large number of free radicals are produced, damaging muscle fibers. This glycogen deficiency increases the consumption of amino acids, particularly glutamine and branched-chain amino acids, which increases the production of ammonia, a highly toxic substance. These are the causes of fatigue. ND4 Cross Up helps balance all these elements by providing them to the body through its intake. The user will be able to maintain their muscles in ideal condition for exercise. Who is it for?
