Our Impact Whey Isolate& is an extremely rich source of whey protein derived from vegetarian sweet cheese, sourced directly from the world's leading whey protein manufacturers. Whey Protein Isolate (WPI) is the ultimate form of whey protein, containing over 90% protein with very little fat and lactose. Having the highest Biological Value (BV) of any known protein, Whey Protein Isolate contains high levels of both essential and non-essential Amino Acids. In the manufacture of our Impact Whey Isolate® we use Cross-Flow Micro-filtration, a delicate process, which uses filters to separate protein from fat, cholesterol and lactose based on molecular size and weight. Impact Whey Isolate® provides over 90g of protein per 100g on a dry matter basis, is low in fat and lactose and rich in calcium. Our production methods help to preserve the biological activity of the whey protein ensuring all the immune-boosting components remain intact. Traceability is a key part of our quality monitoring process and to aid this process we work directly with the world's leading whey manufacturers to ensure we have complete knowledge and confidence in the production process of our whey protein. The protein fractions are: 47% Beta lactoglobulin, 17% Alpha lactalbumin, 1.5% Bovine serum albumin,2% Immunoglobulin G, 0.5% Lactoferrin, 27% Glycomacropeptide.
