One of the most ubiquitous supplemental protein sources today is Whey protein. Whey is the watery part of milk that is separated from the curd in the cheese making process.

Whey has become extremely popular over the last decade because of the fact that it is a complete protein source i.e. it contains a full spectrum of the amino acids necessary for overall health. Whey is contraindicated however, for anyone with dairy allergies or lactose intolerance due to its derivation from milk. Whey protein has two concentration levels; whey protein isolate is the purest form of whey, about 90% of it is protein with a little fat and lactose. Whey protein concentrate, the lower grade of whey, can be anywhere from 25% to 85% protein, and tends to have higher traces of fat and lactose. When it comes to concentrate in a powdered form, it is usually sold at about 80% protein. Whey protein can also be hydrolyzed, meaning the aminos are pre broken down into peptides for easier digestion and a lesser incidence of allergic reactions. Whey protein is one of the highest rated protein sources on the PDCAAS (Protein Digestibility Corrected Amino Acid Score), the PER (Protein Efficiency Ratio) and the BV (Biological Value) evaluation scale making Whey one of the most efficient supplemental proteins…period.
