Gen-Tec Nutrition Hydro PRO Whey Protein Isolate Swiss Vanilla Powder nutrition source and blend this precise blend of ultra and micro filtered whey protein isolate (WPI) and hydrolyzed whey protein isolate (HWPI). WPI is manufactured using cross flow microfiltration which comprises a filter size 4 times smaller than WPC. This extra filtration results in the highest quality whey protein which is virtually free of undenatured protein, lactose, carbohydrates and fat. The digestion rate of WPI is very fast resulting in a rapid increase of amino acids into the bloodstream after consumption. HWPI is the result of WPI being processed even further again using an enzyme hydrolysis process. This chemical free process breaks down the longer amino acid chains to very short di and tripeptides. These short chain peptides immediately absorb into the bloodstream intact with no digestion required. HWPI is the fastest digesting protein food on the planet. The resulting spike in blood amino acid levels signals muscle protein synthesis more effectively than any other protein powder available. Bovine colostrum (containing 20 percent IGG) has been added to this product to support gut health and immunity.
