The main difference between Whey Isolate and Whey Protein is in the manufacturing process. Whey protein is a general term for protein that comes from whey. It can be made from cow’s milk or soy, and it can be processed in one of two ways: with the use of enzymes called rennet casein, which separates the milk into curds and whey, or through microfiltration.
The process of making whey protein isolate is similar to that for whey protein concentrate with one major difference: whey isolate has been treated with heat and a low-level acid solution to remove lactose, cholesterol, and fat-soluble substances like vitamins A and D. This leaves only the purest form of protein in powder form; it takes more than
Whey protein is a type of protein that is derived from the cheese-making process. It’s made up of all essential amino acids. This includes being high in BCAAs, which are an important building block for muscle growth and recovery.
Whey Isolate is a type of protein that is made up of 90% or more Whey Protein. The reason for this increased concentration is to ensure that it has less fat, cholesterol, lactose, and carbohydrates than Whey Protein does.
