Performance begins with the basic ingredients. BioTtech USA Native Whey Isolate is produced directly from fresh milk by pasteurisation followed by micro and ultra filtration at low temperatures, and then pulverisation in a special drying chamber. Due to this unique procedure, the protein structure is preserved in its fullest form and it also remains rich in immunoglobulin (antibody) and lactoferrin (part of your immune system). Also, the raw material is free from chemicals and any other contaminants.
