OK some background. I am pre-op just started my 2 week liquid diet on Monday for my surgery date on December 6th.

I had my preadmin testing at the hospital yesterday then I had to go to a class about the surgery.

In the class, we were told to make sure our Protein powders/protein drinks after surgery contain whey isolate and not whey concentrate.

Now the information I got from the nutrition classes specifically gave pictures and names of acceptable Protein Drinks. Why did they have Premier Protein on there (which is what I ended up getting) if is doesn't have whey isolate? (I checked ingredients as soon as I got in my car and got my shake)

I am going to get my notebook out again this weekend and make sure I am not making this up. I know the one appointment they girl specifically told me to try premier protein in chocolate.

I already shelled out all this money for these shakes so I will be drinking them no matter what.

I think Premier used to be whey isolate a while back and they changed the formula. Perhaps the info with acceptable drinks was put together a while ago and no one knew about the change or bothered to update it?

Anyway, I know many people who drank primarily whey concentrate and did just fine. Yes, whey isolate is absorbed better by the body, but when I looked at the actual numbers for my own research, the difference didn't seem that great to me. It's not like whey concentrate is useless, it's just not quite as good as whey isolate (especially if you are lactose intolerant).

I did about 50/50 isolate and concentrate when I was in weight loss mode and I lost all my weight (200+ lbs) and never suffered from any sort of Protein deficiency or ill health. Tons of people here drink Premier Protein too! I think you will do just fine.
