Digestion rate of protein is a highly overrated concern, mostly blown out of proportion by the protein manufacturing companies.
Whey protein synthesis peaks at the 2-3 hour interval, but is still being digested before and after.
Casien peaks at the 5-6 hour interval, again, hitting the bloodstream before and after.
Once you realize that most bodybuilders eat every 3-4 hours, you realize that what type of protein you consume is relatively meaningless except for two times:
* Post-workout -- should be largely if not exclusively whey.
* Before bed -- should be largely casien, or at least NOT whey.
The rest of the time you want a cost-effective, good tasting protein.
