1,3-dimethylamylamine (DMAA) is an amphetamine derivative w/effects reported as greater than ephedrine but less than that of amphetamine. In just 1 study available, the authors claimed in a now defunct journal that they were able to extract DMAA from geranium oil. Due to arcane FDA rulings, dietary supplements can only be grandfathered into use if they are naturally occurring substances w/documented history of use & benefit. I mention this because most, if not all, peer-reviewed trials have not been able to duplicate the findings of this one study, yet manufacturers continue to claim the "natural origins" of this stimulant. And in fact, the American Herbal Products Association recently stated that DMAA should not be labeled as a derivative of geranium.
reviewing the research letter published early online yesterday in the Archives of Internal Medicine.
And take heart in that Health Canada (our neighbor to the North's version of the FDA) and the US military, both stateside & abroad, have both banned the sale of DMAA. In fact, the FDA just recently declared DMAA a drug rather than a supplement, thus making it illegal for current manufacturers to continue doing so w/o evidence of safety, as required of medications, both prescription & over-the-counter. It's a start! And as expected, GNC and other manufacturers & retailers of DMAA are not too happy about this turn of events. In the meantime, be careful what shortcuts you decide to take in your nutritional habits and watch out for the legal brouhaha about to take place.
