Pulsin Whey Protein Isolate is one of the best quality proteins available from any food source, due to its full spectrum amino acid profile, rapid speed at which it can be assimilated during digestion and a protein content of 90%. Whey protein has always been the top choice for sports people for these reasons, in addition to its mild palatable flavour that blends perfectly with milkshakes and fruit smoothies. Our whey protein is not to be confused with Whey Protein Concentrate: an inferior quality extract with a lower protein content, a cheesy taste and higher levels of lactose.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 and is 100% vegetarian.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.Suitable for Vegetarians.
