Creatine

There's a long answer to this and a short one. Short version: Creatine is used to create ATP which helps power your muscles. Taking creating after a workout "loads" your muscles with creatine and lets you store more of it for next time. There several other beneficial side effects, like increased mental performance, etc., but the main reason most people take it is to help with recovery from workouts. If you do take creatine, get the "normal" version which is creatine monohydrate. Other types of creatine probably won't be significantly better to warrant the price. Don't keep creatine in water too long before you take it - it basically starts to rot before too long. Some people consider that creatine bloats them - if this is the case, you may want to stop taking it. Also, you don't necessarily need to "load" or cycle creatine. Just take the standard scoop - it's more than likely more than you'll need. Any creatine that isn't doesn't get absorbed into your muscles is excreted.

There's a lot of stuff you could look into or take. It depends on your goals and where you are in your training. Just be aware that they're called "supplements" for a reason - your primary concern should be a smart diet and workout plan. The only other thing I would recommend off the top of my head would be fish oil, but that's a good idea for anyone to take.
