What is WPC? (Whey Protein Concentrate)

The growing demand for Whey Protein has led to the production of different types of the products. The two most popular proteins on the market is whey protein concentrate and isolate. For better results, one must put his goals and objectives under consideration while choosing between the two.

The difference between Whey Protein Concentrate and Whey Protein Isolate

The Concentrate

Whey Protein CONCENTRATE (WPC) is often used to describe any type of protein that is ultra-filtered to achieve 25%-85% protein content, after pasteurization. Hence, it has a high level of denatured proteins, cholesterol, fat, and lactose. Furthermore, it is usually much cheaper.

The Isolate

Whey Protein ISOLATE (WPI) is a more pure substance that contains more than 90% whey. Furthermore, it has a lower level of denatured proteins, cholesterol, fat and lactose compared with the CONCENTRATE.

Whey is an excellent source of high-quality protein. It is a liquid by-product of the cheese making process. When the water is removed from the whey, the resulting powder is whey protein concentrate – a great source of essential amino acids, glutathione, cysteine, and calcium. To retain these nutrients, the process of water removal must be carefully managed. For example, heat will destroy several of these nutrients.

Further isolating the protein requires additional processing, and more processing equals a greater chance of damaging the protein molecule. The isolate form is up to 90% protein. The other nutrients have been stripped away.

Benefits of whey concentrate

Concentrated whey, when properly produced, retains the valuable enzymes, vitamins, minerals and proteins that naturally occur in the whey.

Glutathione is in every cell of your body and is critical to maintaining good health. It is a very strong antioxidant, and studies show that whey protein concentrate is very beneficial in helping the body to produce glutathione whereas raising glutathione levels via direct supplementation is difficult
Cysteine is an amino acid that the body uses to help detoxify the organs. It is also important in collagen production. It is a component of glutathione.

When shopping for a whey protein concentrate, look for one that has been cold processed to retain these valuable nutrients. The best quality whey comes from grass-fed cows and is made from hormone-free, pesticide-free, GMO-free milk.

Summary
Both WPC and WPI have many benefits to offer. However, WPC would more appropriate for those seeking economical proteins or proteins that possess more stimulating growth properties. On the other hand, WPI would be ideal for those looking for fast acting high proteins with low fat and those that are quite lactose intolerant.
