What is Whey?

Whey is one of two primary proteins found in milk, and it's essentially a byproduct of the cheesemaking process. Once a starter culture has been introduced to milk as the first step in making cheese, it begins to thicken and coagulate. Milk solids become curds, and the protein-rich liquid is called whey. You may remember opening a yogurt and seeing a clear liquid on the surface, that is whey.

The Health and Fitness Benefits of Whey

While whey is a major ingredient in cheesed like ricotta and brunost, it's also the backbone of nutritional supplements and protein powders. The natural presence of 64 amino acids called glycomacropeptides makes whey one of the most nutritionally complete and balanced proteins. In fact, most of the amino acid isolates you see on the shelves in health and fitness stores are naturally found in whey protein. It's quickly absorbed and metabolized, so it's more easily digestible than many other sources of protein.
