Garcinia Cambogia has become very popular over the years because of its professed weight loss effects. However, not all products that have this ingredient can be 100% genuine and they do not prove to be effectively working on reducing excess fat and calories. These supplements fail to work because this ingredient either does not come from the same source that is proven to be effective as per clinical studies or it is not formulated with accurate dosage. There is another reason for its failure which can be lack of Hydroxycitric Acid or HCA. It is important for buyers to understand what is behind a Garcinia Cambogia Extract Pure.
