is a low-fat formula that is high in protein. Its protein content contributes to the maintenance and growth of muscle mass and also to maintenance of normal bones*. The product also provides carbohydrate energy on which high intensity exercise partially relies. MASS 20 contains whey protein, one of the best bodybuilding protein types. Our ultrafiltered whey protein concentrates provide lactoglobulin, lactoferrin, lactalbumin and immunoglobulin protein microfractions. Whey protein from milk is a so-called complete protein, because it provides 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.
Determination of the nutritional efficiency of protein in the diet is in most cases based on estimating the extent to which dietary protein nitrogen is absorbed and retained by the body and is able to balance daily nitrogen losses. Net Protein Utilisation (NPU) is the percentage of ingested nitrogen that is retained in the body, and the Biological Value (BV) gives the percentage of absorbed nitrogen that is retained. Biological Value is the product of NPU and digestibility. Whey protein has good digestibility and amino acid composition, thus it’s Biological Value is great compared to other dietary protein sources like meat, fish, eggs or soy. We added an extra ingredient to MASS 20 in Creatine.
