Whey Protein concentrates: Whey concentrate has the best flavor with 70 to 80% protein along with some lactose and fat content which is why they are known as the best whey protein powders.

Whey Protein isolate: Isolate contains 90% or even more protein with an insignificant quantity of fat or lactose. 

It also lacks any other beneficial nutrients that are usually found in the whey protein concentrate.
