I looked at the ingredients and there was only one ingredient that I didn't recognize:
Guggul - Guggulsterones (This information was provided by them, not by a third party)
Guggulsterones have been used in ayruvedic medicine in India for thousands of years. Guggulterones, or guggulipids, extracted from to Comiphora mukul plant are believed to help regulate thyroid function, which in turn among other functions regulates metabolism.
Research studies using guggelsterones showed a reduction in triglycerides (fats) and LDL (bad) cholesterol as well as increases in HDL (good) cholesterol7. Further studies have shown similar effect of guggulsterones related to reduction of body fat8.
It looks like a pretty standard diet pill to me, containing ingredients that haven't been proven to be effective and may be potentially dangerous (synephedrine).
