Does Garcinia Cambogia really work in helping you lose weight?

I have been looking at a lot of weight loss supplements and I'm a bit confused on picking the right one. One that really took my interest is Garcinia Cambogia and I saw it on Oz. But does it really work? If it does please suggest a good product.

I'm using Garcinia Cambogia Plus. Here's their website www.choicenutritionsupplements.com
