The only supplements you really need are:
Omega 3 fish oils / capsules
And possibly a strong multi-vitamin each day.
Other than that, get your daily nutrition sorted and you won't need supplements at all.
As Tourney rightly pointed out, creatine is used by athletes and body-builders to help the muscles retain energy for performance benefits.
As such, creatine CAN help you push harder and do more intense workouts, which would then help you lose weight. But creatine won't DIRECTLY stimulate fat loss.
All the best
