Our Acid Whey Protein is a Whey Protein Concentrate 80 (WPC80) manufactured from high quality vegetarian Acid Cheese Whey produced by a leading western European dairy. Having the highest Biological Value (BV) of any known protein Whey Protein contains high levels of both essential and non-essential Amino Acids. Our Acid Whey Protein is instantised so mixes instantly with a very bland flavour profile. Of course it also has excellent nutritional properties including over 80% protein (dry basis). Traceability is a key part of our quality monitoring process and to aid this process we work with dedicated European whey suppliers so that we are able to control the supply of whey right back to the source. Acid Cheese Whey, or as it’s sometimes known as Sour Cheese Whey, is obtained during the production of acidic cheese such as cottage cheese. The more common Sweet Whey is derived from hard cheese such as Cheddar or Swiss Cheese. Whey Protein sourced from Acid Whey has numerous benefits including the fact it is particularly rich in natural beta-lactoglubin. This is the protein able to trap the lipidic molecule. Other benefits for whey derived from acid whey over sweet they are: Increased amounts of naturally occurring Lactoferrin (1%). Naturally higher Leucine levels which highly stimulates protein synthesis. Naturally higher Cystein levels which will enable faster glutathion synthesis. Naturally higher Typtophan levels could reduce stress and improve sleep. The protein fractions of Acid Whey Protein are: 60% Beta lactoglobulin, 20% Alpha lactalbumin, 8% BSA, 10% Immunoglobulin-G (IgG), 1% Lactoferrin, 1% Others. This is an Acid Whey Protein. If this doesn’t mean anything to you, we then recommend you choose our Impact Whey Protein® which is from sweet whey.
