The Difference: Whey Protein Concentrate (WPC) and Whey Protein Isolate (WPI)

After a sufficient protein concentration is achieved, the liquid can be spray dried to form whey concentrate powder that consists of up to 80% protein by weight. The remaining 20% of the whey concentrate powder contains carbohydrates and fats. If different processing steps are used to reduce the fat and carbohydrate content of whey, a whey isolate powder containing 90% or more protein by weight can be produced. 

Overall, the processing steps used in the production of whey isolate result in higher protein content and lower fat and carbohydrate content per serving. However, the types of amino acids found in both forms of whey are virtually identical, since they are derived from the same proteins.

In addition to having lower total carbohydrate content, whey isolate also has lower lactose content. This means that it could be a better choice for those who are lactose intolerant. Please see our lactose-free whey isolate. Nevertheless, the amount of lactose in both forms of whey protein is likely to be low enough for those who are lactose intolerant to use. In addition to their nutritional differences, there are cost differences between these two types of whey. Generally, whey isolate is slightly more expensive than whey concentrate. While this makes sense based on the higher purity of whey isolate, taking a larger quantity of whey concentrate can bring you the same dose of protein, often at a lower cost. There are also many whey protein powders on the market today that is a blend of the two. Whey Protein Isolate also may filter out some vitamins during the purification process. 

If you’re looking to supplement your protein intake to aid in fat loss, and muscle gain, or are just looking for a meal replacement, either whey concentrate or whey isolate is an amazing place to start.
