Dear Stacker 2,


Stacker 2 bills itself as the world's strongest fat burner. It is made up of Ephedra, Kola Nut and White Willow Bark.


Scientist at the University of California, San Francisco, at the request of the Food and Drug Administration, reviewed 140 reports of serious problems with Ephedra-containing products. Among the problems they found:

  • 43 cases were definitely or probably related to the supplements
  • 44 cases were possibly related to the supplements
  • 10 deaths
  • 13 people left with permanent disabilities

The New England Journal of Medicine (NEJM) subsequently published the study and warned " dietary supplements that contain Ephedra alkaloids pose a serious health risk to some users." The NEJM indicated that since Ephedra is considered a stimulant, people who have kidney disease, those with pre-existing heart disease, high blood pressure, overactive thyroid, psychiatric disorders or those with a history of seizures should avoid it.


Since Ephedra is considered a natural herb the Food and Drug Administration (FDA) have not regulated it in the past. However, in light of the recent medical concerns the FDA is now considering issuing some guidelines for its use.


To get back to your question, because of the above concerns, TeenHealthFX strongly discourages any of our readers from using any products containing Ephedra. As a note, TeenHealthFX does not recommend taking any supplements not only because of the potential negative side effects, but because as a teenager your body is still growing. Supplements can interfere with the growth process. As always if you are interested in losing weight or becoming fit we advocate eating healthy and regular exercise.
