The recommendation to take Garcinia Cambogia started about 20 years ago. I tried it then with no results then and am pretty sure I tried more than 1 brand because I was pretty despirate at the time. I have since learned there's no easy pill or powder to loose weight with. If there was all the doctor's would recommend it to their overweight patients. I have been a nurse for a very long time and I tend to think Dr. Oz is full of fluff, but he is a charming man. My wish is not to offend anyone........it's just my humble opinion.
