Despite FDA Warning, Sports Supplements Still Available Online: Study

DMAA sports supplements have been linked to at least two deaths and the U.S. Food and Drug Administration sent warning letters to 10 manufacturers last spring about a lack of data on their safety, but a new study finds these supplements can still be purchased online.

DMAA (dimethylamylamine) is a pre-workout supplement used by athletes to build muscle. Some research suggests that it may narrow blood vessels, which can elevate blood pressure, and may set the stage for a heart attack. Canada and the U.K have banned DMAA from all supplements.

Now, a small study published online Dec. 3 in the Archives of Internal Medicine reports that all 16 of the products mentioned in the FDA’s warning letters are still available through online retailers.
It’s good to know that the FDA is right on top of enforcement.

From the Journal:
The stimulant DMAA, also known as 1,3-dimethylamylamine, has been the subject of much controversy.1 In the United States, it is currently marketed as a dietary supplement, primarily in products promoted as a preworkout supplement for boosting strength, energy, and power. Two of the most prominent supplements containing DMAA are “Jack3d” and “OxyELITE Pro” (USP Labs) However, there are over 250 commercial dietary supplements containing DMAA on the market.2
