What is the best diet supplement?

I be honest I have no idea about which is the best diet supplement. I know that for many people dieting is hard work so the thought of using a supplement appeals to them and in these cases I think it's important to be honest with yourself and make sure you need it.

If you really think you do, then talk to your doctor or a health professional. Try and stick with all natural products and make sure you read reviews of these products from other genuine users.

I have just started an intense fitness plan that I trust and they recommend quite a few dietry supplements.
