Whey protein is a mixture of proteins isolated from whey which is the liquid part of milk that separates during cheese production. Whey protein is considered a complete protein as it contains all 9 essential amino acids. It is low in lactose content. It is a mixture of beta-lactoglobulin alpha lactalbumin bovine serum albumin and immunoglobins. Taking whey protein is a convenient way to add protein on top of your daily intake. This can be important for bodybuilders and gym enthusiasts as well as people who need to lose weight or are simply lacking protein in their diet. Whey is generally well tolerated though people with lactose intolerance need to be careful and some people may even be allergic to it.
