Yes, I use whey. It's the only protein supplement I use. I've read nothing but good things about it, and best yet, it's the only type that I find tasty. I avoid soy protein because of the estrogens in it and because thyroid problems run in my family. Soy can make thyroids run amok. I've also tried brown rice protein, but I think it tastes terrible.

My favourite smoothie recipe is a scoop of whey protein, a banana, a big dollop of natural, unsweetened peanut butter, and a cup of milk. Ice is optional. I think this is pretty tasty, whether I use chocolate or vanilla whey, and it's also very filling.
