Is taking pure green coffee bean extract and garcinia cambogia extract good and safe for weight loss?

NO. Don't use it: Garcinia cambogia is in most weight loss supplements, and can cause liver failure.It was also used in Hydroxycut which was taken off the market as people died from using it. I see a handful of patients per month with abnormal liver tests after using this medicine. I would NOT recommend it. There is no "magic pill" for weight loss. Diet and exercise remain the #1 way to lose weight and keep it off
