Pulsin Whey Protein is produced from sweet whey, a natural by-product from cheese manufacturing where milk is separated into curds (casein) and whey. The whey protein is isolated using a combination of Cross-Flow Ultrafiltration and Microfiltration techniques, which preserves the delicate structure of the whey protein without causing denaturation. The resulting protein isolate is then mixed with soya lecithin to improve miscibility. All of our whey protein is produced from UK milk from grass fed cows that have been reared without hormone treatment and is 100% vegetarian. Whey protein is best used mixed into a fruit smoothie or milkshake with a serving size of 10-20g. Our favourite is banana and mixed berries with rice milk Whey protein can also be mixed into a glass of milk or yogurt without noticing any difference in taste. We do not recommend cooking whey protein as it can become denatured by heat. Whey protein isolate is absorbed so effectively that some sports people prefer to combine it with another slower releasing protein to lengthen the duration of satiety and to give a sustained amino acid release into the bloodstream; this can be particularly effective when consuming a protein shake before going to sleep. We find that whey protein and pea protein combine particularly well for this purpose, at a ratio of approximately 1:1, and hence we use them both in the Protein Sport bar Ingredients: Whey protein isolate, soya lecithin (trace).
