Our whey protein (Whey PROtein+) is a pure whey protein concentrate (WPC) obtained by ultra-microfiltration through membranes. This protein is characterized by its high solubility, even at an acidic pH (in the stomach), allowing for rapid digestion (Wilson J. et al., JISSN. 2006) without digestive problems. It quickly delivers amino acids into the bloodstream (hyperaminoacidemia), so that they can be used by muscle cells for recovery, both after training and throughout the day. In addition, and most importantly, we have improved its formula by adding the branched-chain amino acid Leucine in sufficient quantity to ensure that we reach at least 3 g/serving recommended by science to activate the mTOR pathway, which induces protein synthesis and thus optimizes muscle recovery processes (Jäger R. et al., JISSN. 2017). We have also added L-Glutamine because this amino acid, among other functions, seems to improve the functioning of the immune system, serving as a fuel (Calder PC et al., AA. 1999), mainly for macrophages and lymphocytes. In addition, whey protein supplementation itself may also be beneficial for the immune system, as amino acids are signaling molecules that, among other things, regulate lymphocyte function (Bumrungpert A. et al., JMF. 2018). The amount per serving is 5.9 g, including the added protein and the precursors naturally present in whey protein. Since it is obtained by ultra-microfiltration through membranes, the protein does not suffer any damage or loss of essential amino acids, such as lysine, which is the most heat-sensitive amino acid. The lysine concentration is used as a quality reference for this type of protein. And, like all Crown Sport Nutrition® products, it boasts spectacular taste, solubility and digestibility
