Protien Powder--Soy or Whey

x2

 In what application?  There is correlation between soy (not soy based protein supplements) consumption and reduced rates of cancer but correlation is not causation.

 Whey isolate is a very good source of protein for recovery after exercise as the concentration of Amino acids is high.  Egg was the golden standard at one point (hence Rocky's raw egg shakes).  Soy is good for pre and mid workout fuelling as it produces less ammonia.

I use both, although I tried to eliminate any dairy products from my diet I still use Optimum Nurtition 100% Natural protein powder for my everyday nurtition shake because soy/pea protein are just too damn chalky! I need to use at least 12-14 ozs of liquid in that shake and that much of soy/pea protein is too much.

When I have a hard enough workout to think I would benefit from a recovery shake I use Nitro Fusion which is an all natural tri part protein with a scoop of glutamine and about 8ozs of rice milk.

casein before bed and during the day, whey before and after workouts.

I've had soy protein, but can't find a brand i can stand the taste of, much like egg protein.

x2  I get mine at Costco and it's a combo of whey and casein, no soy.

Me too.  I also had an allergic reaction to soy during allergy testing.  So far, no reaction while eating, but I do limit the amount of soy I eat.

go with soy, all the whey...

Ditto.  I hate the gritty soy thing.  I like Hammer's Whey protein since it's completely lactose free!
