You should get tested first, chances are you don't need supplements if you live in the tropics and spend much time at all out in the sun. If you're a vampire like me (I rarely go out much during the day, my car is even in the garage :) ) you might need supplementation though. If you're an active person outdoors a lot the chances you need supplements are unlikely. Go to a doctor and get some blood tests, they can spot all kinds of deficiencies and tell you how normal things look
