The U.S. Food and Drug Administration has ordered fitness supplement companies to immediately stop selling popular bodybuilding and weight-loss products containing DMAA, because of the substanceâ??s potentially fatal side effects.
The agency has determined DMAA which is sold as 1,3-dimethylamylamine, methylhexanamine, or geranium extract is a synthetic substance that could cause heart attacks by elevating blood pressure in users. There have been 42 public complaints about products containing DMAA, indicating it might be linked to other serious health effects including nervous system and psychiatric disorders as well as death, the agency said Friday in a news release.
Products containing DMAA were pulled from military exchange store shelves in December. The substance has fallen under increasing scrutiny since Stars and Stripes reported that DMAA was found during toxicology tests of two soldiers who suffered heart attacks and died during physical training at a base in the Southwest U.S.
