So What's The Big Difference Between Whey Protein Isolate and Concentrate?
Most of the whey protein powders you find will contain mostly whey protein concentrate with some whey protein isolate mixed in. You will also find a lot of pure whey protein concentrate, and some whey protein isolate. Whey protein isolate is more expensive than concentrate because it is more pure and has a higher biological value (BV). Whey protein isolate contains more protein with less fat and lactose per serving. Usually, isolate contains 90-98% protein while whey concentrate contains 70-85%.
Whey protein isolate is the highest yield of protein currently available. Because of its chemical properties, whey protein is the easiest to absorb into your muscles. Obviously, with its high concentration, whey protein isolate would be the best to use, there is a downside. Whey Protein Isolate is more expensive, and just because it's more pure, doesn't mean it'll give you more muscle and size. Its extra concentration may not justify the extra costs for you.
To use Whey Protein Concentrate or Whey Protein Isolate?
So when all's said and done, should you use whey protein isolate, or concentrate? On the plus side, whey protein isolate is more pure, but it also costs more. Most protein powders you find will have mostly whey protein concentrate with some isolate blended in.
For most people, it is not worth the extra money to use pure whey protein isolate. Using whey protein concentrate with isolate blended delivers just as good results with less costs. Many bodybuilders say that they don't notice whey protein isolate giving them any large gains over whey concentrate.
Note: If you are lactose intolerant, whey protein isolate is a better choice because it contains less lactose.
