Differences in Whey Isolate and Whey Concentrate?

[Veretta9]

I have always used optimum nutrition's protein--the 100% whey kind---I just received 100% whey isolate from Allthewhey.com--and was wondering if there is a difference in the two in terms of preserving muscle and building muscle? Does anybody really know any difference in the two when taking them?

The difference is the amount of protein you get.
The best protein is something like ISO AGB where you have an isolate that is nearly 98% pure yet has the digestabilty rating as high as baby food.

what would you say a pure isolate--such as the one I just got from allthewhey has compared to optimum nutrition's 100%whey has? How can you tell?

"optimum nutrition's 100%" is not 100% isolate. It's a blend of isolate and concentrate. It's 100% whey but not 100% PROTEIN.
You have to look at the protein content and how well it breaks down in your stomach. That's why digestability is an issue.
ISO AGB uses isolate from BiPro. BiPro makes the highest protein content, highest digestabilty content there is.
