Years ago when I first started Proteinfactory.com the first product I sold was whey isolate. CFM to be exact. And the reason I sold CFM whey isolate was because it was not a whey protein concentrate. In addition, a whey isolate is much easier on the stomach and gave you no gastrointestinal problems from the lactose like in whey protein concentrate. I remember I bought about 200lbs and posted on message boards that I had whey isolate for sale. “Whey Isolate, what is that?”, most people asked me. I had to explain to them that a whey isolate was 90% protein with no fats and carbs and whey concentrate was 80% protein with fat and carbs. A whey isolate is a superior product. But the problem remained in how does someone know if the protein they have is a whey concentrate or a whey isolate. Because at that time alot of supplement companies we’re just listing “whey protein” in the ingredients of their whey protein and you so wouldnt know if you were drinking a whey concentrate or whey isolate.
So what I did was start telling people “to do the math”. Meaning you would take the protein grams per serving and divide it by the serving size. That number would give you the protein percentage of the powder. For example if the protein grams per serving was 20 grams and the serving size was 30 grams the protein percentage would be 66% protein. This would be a good indication of whether the protein was a whey concentrate of whey isolate. Typically if the protein percentage was under 80% it would be a concentrate and if the powder was over 80% it would be an isolate.
Fast forward to 2014 and now (if you’re a reader and/or customer of Proteinfactory.com) you should know that this mathmatical method that I taught people 15 years ago is out dated now. Its out dated because of companies labeling their whey proteins as “food” instead of a “protein supplement or dietary supplement” and most recently “protein spiking”.
Have no fear because now I’m going to teach you a simple way that requires no math to determine if the protein powder is high quality or not.
First and foremost you need to make sure that you are buying a whey protein supplement, not a whey protein food. If you have not read my article on that please read it first here. But you always want to make sure you but a whey protein supplement with a supplement facts panel on the back, NOT A NUTRITION FACT panel.
Secondly you want to make sure the whey protein is listed INSIDE the supplement facts panel not on the outside. When a company lists their protein on the inside of the supplement facts panel it means that you will know EXACTLY how much of that ingredient is used in the powder.
For example, many companies use protein blends. They will take whey protein isolate and whey protein concentrate and call it a whey blend. They do this to make it look like they are using isolate (the superior form of whey & more expensive) when all along they are using mostly whey protein concentrate. And forget about calling them up and asking them how much of each. They will give you the old “proprietary blend” excuse.
However to avoid this if the whey protein isolate and concentrates are listed INSIDE the supplement facts panel you can see EXACTLY how many grams are used of each.
And that’s it. Buy a whey protein that is labeled as a dietary supplement and make sure the protein ingredients are listed INSIDE the supplement facts panel so you can know exactly how much of each protein is used if that protein is a blend.
