What is whey protein isolate?

Whey is by-product of milk generally derived while cheesemaking. After processing milk with few enzymes and heat we are able to separate the liquid and the solid part of milk.

This liquid is termed as whey which contains the maximum amount of protein. After this, it is converted into the powder form for the usage of consumers.

This whey is concentrated form of whey. From the further filtration of this product, we finally get the whey protein isolate which has very minimum amount of lactose, carbs and fat contents.

What is the difference between whey Isolate and concentrate? 

 We get whey isolate and whey concentrate from the same product. The only difference is in the last step of the processing, which extracts the maximum amount of carbohydrates and fats present in the solution.

The additional effort taken for the cold micro-filtration process ensures that the protein isolate contains higher density of protein than protein concentrate. This is one of the major differences in these two components.

Many protein shake takers complain that they are facing digestive issues or noticeable bloating after consuming whey protein. These may cause by the lactose present in the whey.
