Whey Protein Isolate vs Concentrate

Whey protein has become an increasingly popular source of protein, but not all whey is created equally. There are two main types of whey protein used in supplements- whey protein concentrate and whey protein isolate. It should be noted that there are considerable differences in the way each is produced as well as the nutritional content of each.

So which one is better? Here are the facts:

Whey Protein Isolate

Whey Protein Isolate is produced from pasteurized whey and is a byproduct in the making of cheese. During this process, non-protein elements removed. Whey protein isolate has all the amino acids that we need in our daily diet, making it a complete protein.

Whey protein isolate has high levels of branched chain amino acids, which promote muscle growth since it can be metabolized directly into muscle tissue. Whey protein isolate also contains a high level of leucine, which also promotes muscle growth and loss of fat tissue. Whey protein isolate’s high levels of cysteine also helps to boost the immune system by elevating the body’s level of glutathione.

Whey Protein Isolate Key Points:

•Higher protein concentrate

•Less lactose, if any at all

•A complete protein

•50% more leucine than soy protein isolate

•High level of cysteine

Whey Protein Concentrate

Whey protein concentrate is much easier and cheaper to produce than isolate. Concentrate also retains more lactose per serving. Because there is more lactose, there is considerably less protein than in isolate. Whey protein concentrate also tends to have more fat than isolate.

Key Points:

•Cheaper

•Less protein

•More lactose and fat

Smoothie Complete is made with 10 grams of lean whey protein isolate. Many companies use a whey protein concentrate and add a miniscule amount of isolate, to keep the cost down and make it appear to customers that they are consuming a product with high quality whey protein isolate.
