Not all protein is created equal, here is a handy guide to make it easier when you are shopping for your next protein powder.
The Types of Whey
The most basic and cheapest form of whey protein. It typically contains 70-90% protein per serving with the rest being lactose and fat.
Whey protein isolate is created when whey concentrate is microfiltered removing basically everything that isn't protein. This means you are left with more pure protein without fats and even lactose.
Hydrolyzed whey goes through an addition process where the protein is exposed to heat, acid or enzymes that break down the bonds hold amino acids together. Protein makers typically claim this process 'pre-digests' the protein which enhances bioavailability.
Reading a Label
Supplement makers use proprietary blends when they don't want you to know exactly what is in their product.
The FDA requires ingredients to be listed by their predominance (weight) in the product. So, our label for example (below) we show exactly what you get in each 30g scoop.
In this example below, you can see this maker uses a "Proprietary Blend Matrix" - a proprietary blend.
This means you do not know how much of each type of protein you are getting, it contains the most of whey isolate and the least of skim milk, but how much?
By using a blend, they are able to show they use whey isolate, a high quality whey, but in reality 'blend' it with a lot of other lower quality proteins as well.
This practice is done in all supplements, not just protein. So next time you are shopping for a nutrition product, check the label.
