I lift weight ince 5 month, with a good diet and intense workout, I lose some fat. I was not overweight but I have too much of fat for me. If it still remains a little bit of fat on my abs, do taking creatine will help me to get rid of it ?

Creatine is a good supplement, but not a fat burner. What it will do is help you work a little harder for a little longer in the gym. You'll be able to squeeze out that last rep more often.

For fat on the abs, look at your diet. Bodybuilders have a saying "Abs are built in the kitchen, not the gym." Cut out all white carbs from your diet (sugar, bread, rice, pasta, potatoes, cereals) and replace with protein, healthy fats and green vegetabls.
