Caseins and caseinates make the other group of milk proteins besides whey. They are high in the essential branched-chain amino acids (BCAA’s) and in L-Glutamine (higher than whey), the most abundant free amino acid in human blood. NIGHT PRO’s calcium caseinate and micellar casein are so-called complete proteins, because they provide the body with all necessary amino acids, including the 9 amino acids (i.e. Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine) that are considered essential for life, because the body cannot synthesize them. They are also the substantial sources of calcium. NIGHT PRO can be used when meals are too far apart for some reason, or before going to bed. If you use pre- and intra-workout nutrition (including protein or amino acids), it may be preferable to include it as your post-workout protein! NIGHT PRO is a low-fat product with a high protein content. Its proteins contribute to the maintenance and growth of muscle mass and also to maintenance of normal bones. Calcium contributes to normal muscle function, energy-yielding metabolism and neurotransmission. It is needed for the maintenance of normal bones and teeth.
