The US Food and Drug Administration is warning that DMAA-based bodybuilding products such as Jack3d and OxyElite Pro are illegal and may present serious health hazards to bodybuilders.
DMAA is a shortened form of the stimulant known properly as dimethylamylamine.
It is used by many bodybuilders to achieve a training boost, extra focus and, many claim an increased pump and vascularity.
But in a public warning the FDA said that the stimulant did not qualify as a legal dietary supplement ingredient and that it could raise blood pressure, potentially causing heart attacks and other health problems.
In a little over five years the FDA received reports of 86 health problems, including at least five deaths, in consumers who used DMAA products.
There is no direct scientific evidence proving the stimulant directly caused the health problems but agency officials warned people not to consume the ingredient.
Daniel Fabricant, FDA director of dietary supplements programs, said: ““We are very concerned. We think consumers should stay away from products containing DMAA.”
Steve Mister, president of the Council for Responsible Nutrition, a trade group, responded saying: “The FDA has spoken and we are urging the industry not to manufacture products with DMAA. Retailers should heed the advisory as well.”
A lawyer for USPlabs, the Dallas company that markets Jack3d and OxyElite Pro, said his client disagreed with the FDA's position.
