USN Whey Isolate is formulated with pure whey protein isolate. This ultra-pure protein source has gone through a more intense & meticulous cold filtered purifying process to deliver a product with far less fat & carbohydrates than regular whey protein concentrate. The system to analyse & prove the quality of a protein source is called PDCAAS (Protein Digestibility Corrected Amino Acid Score) which is utilized to establish the percent daily value for nutrients on food labels. The maximum PDCAA Score is 1.00 & whey protein isolate (WPI) received a score of 0.99 to 1.00. WPI is one of the best sources of essential amino acids. It naturally contains high levels of Branched Chain Amino Acids (BCAAs). USN Whey Isolate mixes instantly, tastes great & is ideal during low carbohydrate diets too. Use it before & after workouts or any time of the day between meals.
