OLIMP Whey Pro Matrix is a unique highest-quality complex composition of whey protein concentrate (WPC), isolate (WPI) and hydrolysate (WPH) and of glutamine peptide, supplemented with anti-catabolic substances (glutamine and taurine), metabolic activators (choline and inositol from lecithin) and vitamins and minerals, ensuring the normal course of metabolic processes during vigorous physical exercise and increased intake of proteins. Whey proteins are characterised by the highest nutritional value and anabolic activity of all dietary proteins. Owing to their high nutritional value and anabolic activity, whey proteins are considered the most valuable source of dietary protein for high-performance athletes and physically active people. The composition of whey protein concentrate, isolate and hydrolysate leads to the obtaining of an extraordinarily active composition of whole functional whey proteins, pharmacologically active peptides and micropeptides and pure free amino acids. This composition owes its high nutritional value to the highest possible assimilability and optimal proportions of exo- and endogenous amino acids with and an exceptionally high share of branched chain amino acids (BCAA) and glutamine. The high anabolic activity, apart from the high nutritional value, results from metabolic parameters of whole whey proteins as well as of peptides and micropeptides formed by their hydrolysis, which act similarly as anabolic peptide growth factors. They facilitate the transport of amino acids into muscle cells and stimulate anabolism. They form an antioxidant barrier. They stabilise lysosomes and inhibit the activity of catabolic lysosomal enzymes. They reinforce the cardiovascular, nervous, and immune systems. The addition of glutamine peptide, L-glutamine and taurine (organic nitrogen deposits) substantially increases the nitrogen balance index of the composition of whey isolate, concentrate and hydrolysate, which extraordinarily potentiates the anti-catabolic and anabolic activity of the product.
