whey protien

I would like to know if protien really works like they advertise in these magazines. My husband works out pretty much everyday in one way or another. He reads these magazines relegiously, he drinks this protien everyday the whey and  and at night he drinks the casien and he also does the creatine every day and then has diahrea afterwood. I try to talk to him about it, but it seems he is convinced by these magazines. Please help!!!! Angie
