Use whey protein. Honestly, if you've never taken it before, just start out with the cheap $15 crap from Wal-Mart. None of the flavors taste good. But I'd just start out with just skim milk and a banana blended with two scoops of the protein.
I'm assuming you've started a workout regiment. Make sure you have a good diet too. Too many people will just make a protein shake and then leave the rest of their diet alone. Yeah the extra protein helps SOME. But for the most part you're wasting your money because 90% of that protein will go straight through your body and into the toilet. Try to eat six meals a day. It's really not as hard as it sounds though.
8 AM: Bowl of oatmeal and a piece of toast
10 AM: Protein bar (I use the Big 100 bars. Like I said, since you're just starting it really doesn't matter THAT much.)
12 PM: Two turkey sandwiches
Right after you workout: Protein shake
6 PM: Grilled chicken and a baked potato
8 PM: Cottage cheese or yogurt
