I've read SO much of this around the boards here. Whey is all they seem to have in stores around here. It seems that you absorb more of the protein in a Casein based mix?

This is my understanding based on everything I've read here, correct me if I'm wrong.

And if this is correct can someone direct me to a store, online or otherwise, where I can find this kind of Casein mix (shake)? I eat a lot of tuna, lean beef, chicken etc... (and virtually NO dairy by the way) - and it would be nice to have something at least effective to supplement with. I've been taking this whey crap religiously.

thx
