Whey protein is a supplement made from the liquid part of milk that separates during the cheese making process. It comes in several forms, including WPC (Whey Protein Concentrate), WPI (Whey Protein Isolate), and WPH (Whey Protein Hydrolysate), or as a blend of these types.
It is primarily used to increase daily protein intake to help build and repair muscles after exercise. Because it is a complete protein, it contains all the essential amino acids, which are the basic building blocks of protein that the body cannot make on its own.
While Whey Isolate is a type of whey protein, it is more refined than the standard Whey Protein Concentrate.
| Feature | Whey Protein (Concentrate) | Whey Isolate |
|---|---|---|
| Protein Purity | Lower protein percentage per scoop | Higher protein percentage per scoop |
| Fat and Sugar | Contains more lactose (milk sugar) and fat | Most lactose and fat are removed |
| Digestion | Standard digestion speed | Faster absorption into the bloodstream |
The process begins by filtering the liquid whey left over from cheese production. This liquid is processed through membranes to separate the protein from the water, fats, and sugars. The resulting liquid is then spray dried, which means it is turned into a fine powder using hot air, and then mixed with flavourings or sweeteners before being packaged.
This supplement sits in a mid-range price bracket. This is because the raw materials are a byproduct of the massive dairy industry, making them widely available, but the industrial filtration and drying processes required to create a shelf-stable powder add to the final cost.
