New Whey Liquid Protein is more bioavailable than regular whey, whether it is isolated or concentrated because of the speed in which whey passes through the stomach and small intestines. This high speed causes a significant amount of malabsorption.
Additional malabsorption from existing whey drinks and bars is the result of the denatured protein molecules. What is Denatured protein? Denaturing occurs when the normal structure of the protein molecules are broken down into an abnormal structure as a result of heat or acid processing (typically for the purposes of pasteurizing or baking protein drinks and bars).
This denatured protein can be much more difficult to absorb than non-denatured protein. In contrast, New Whey Liquid Protein is extremely heat stable because it is made completely with peptides and not denatured in any way.
