Does Protein Source Matter in a Blend?
Protein sources included in a blend really matter! It is also great to see the ratio of the blend as well. Many companies will start their blends with Whey Protein Concentrate (which can be as low as 34% protein). Then they may follow it up with Whey Protein Isolate. On paper that looks good, but really they may be using cheap protein to fill the majority of the serving size, with very little high quality protein.
When you look at the label, you want to look for call outs like WPC80 – this means that this whey protein concentrate is 80%. This is a quality WPC. If the label starts with Whey Protein Isolate then you know it is using the 90% quality protein first followed by others.
So yes, the type of protein matters in a blend because if low quality protein is used first, it can be an ineffective blend that is a big waste of money.
Ideally, you want your blend to start with Whey Protein Isolate or Whey Protein Concentrate 80 (Hydrolysate is great too). Make sure you hold your brands accountable and only put your money toward quality protein blends, like the ones you will find on this list.
