Already Something Else to add:

One of our friends (Alex H.) brought up a good point:

Stay hydrated when you're working out and even when you're not. If your pee is yellow, you probably aren't drinking enough water.

He also suggested baked sweet potatoes as another healthy food. They have:
-Complex Carbs -Beta Carotene -Vitamin C -Vitamin B6 -And dietary fiber to make all that protein powder get out easier

Also on the other hand, multivitamins might be a good investment if you feel like you aren't getting everything you need from the food you eat already. Generic brands and big bottles are good for you and your wallet. You don't need to have one every day but popping one at breakfast every couple days wouldn't be a bad idea. Too much of a good thing can be a bad thing.

More on Creatine: Someone didn't get the joke about livers exploding so I guess we'll go a little more in depth. Googling it for light research basically just ran into a lot of sites saying yes it helps gain mass, yes a lot of that mass is water weight till later on, and when you get off creatine your body might seem to "deflate" or get smaller because of losing all that extra water. Looks like most of the side effects like cramps and such occur because people don't drink enough water.

These go a lot more in depth than we do.

It probably won't make your liver explode.
