I would research creatine before taking it. If you really want a great supplement, be sure to balance your essential fatty acids because... well... they really are essential. Take Carlson's Fish Oil to get EPA and DHA. Many omega-3 supplements have ALA, but you need the EPA and DHA too, which not many sources have. Also, get some GLA from blackcurrant oil or any other source you can find, it is an omega-6. Your intake of omega-3 to omega-6 should be anywhere from 1:1 to 1:3. There are many supplements I take, but if I had to choose one, it would be a high quality, potent fish oil like Carlson's, which is the gold standard. If your joints are bad, I have found hyaluronic acid to do wonders for my joints and eye sight.
