Blended whey proteins can mean a number of different things. Originally the term in Canada was meant to distinguish blends of whey protein concentrate and isolate from pure whey isolate. The issue has become a bit confused as bodybuilding supplement manufactures in Canada have found the benefits of blending whey protein isolates with non-whey proteins, like micellar casein and egg protein isolate.
Each type of protein has a biological value (BV) that has been calculated for it based on the whole egg, 100, which was considered the most bio-available protein in nature. More recently whey isolate sports nutrition supplements have been found with even greater values, with 104 for concentrate and 157 for whey isolate. But BV and bio-availability is not the be all end all for quality of whey proteins in Canada. It has been found in bodybuilding supplements that carbohydrates are needed for maximal absorption and some protein blends also are beneficial.
Unfortunately blends of whey protein concentrate and isolate are not one. They are often produced because it is cheaper then pure isolate products, and the BV depends on the ratios of each protein. I will stop short of others who see them as useless, and say that they offer a value for money as long as one understands they are substantially inferior to pure whey isolate bodybuilding supplements in Canada. For people in Canada who are serious about bodybuilding, sports nutrient, and fitness I would always recommend pure whey isolate supplements. If you are putting in 100% effort you should expect that same 100% from your supplements. But still, many people do see them as a good value for their money and a good source of protein.
Blended formulations in Canada that are excellent sports nutrition supplements are blends of micellar casein or egg isolate protein and whey protein isolate. These blends have synergistic effects in the body. Whey isolate is fast acting quickly absorbed where casein is slower and feeds the body after the whey is used. These bodybuilding supplement formulations are improvements upon the natural balance of proteins found in milk. Depending on the ratios of the proteins used these blends may be appropriate for day or night use.
