Warning on gym 'killer'

POPULAR supplements taken before exercise face a possible ban in Australia after testing positive for an ingredient believed to be behind several overseas deaths.

Food Standards Australia New Zealand (FSANZ) has issued a warning about DMAA, also known as 1, 3-dimethylamylamine.

FSANZ deputy CEO Melanie Fisher said the products were typically used as a pre-workout supplement, but had been the source of adverse health reports.

DMAA is a stimulant popular among people looking to build muscles or lose weight, but has been listed by the World Anti-Doping Agency as being 'prohibited in competition'.

"DMAA has been linked in other countries with various adverse health effects including high blood pressure and vomiting, and there have been a couple of adverse health reports in Australia," Ms Fisher said.

"Regulatory agencies are working together to assess the products' safety and are currently seeking the assistance of retailers, importers and distributors on a withdrawal."

The Federal Department of Health and Ageing is also looking at whether DMAA should be prohibited.

One of the products to test positive, Jack3d, was found recently to have been used by mineworkers on shifts to manage fatigue, according to the Queensland Government's Chief Inspector of Coal Mines.

Overseas, the United States Army has been investigating whether certain dietary supplements, including those found to have DMAA, may have played a role in the deaths of two soldiers.

Both died after having heart attacks during fitness exercises in 2011.

Cotton Tree's International Fitness Studio personal trainer Mark Gunther recommended taking the DMAA products only when trying to set a personal best.

"So long as you don't abuse the stuff, and use it only every now and then, the side effects would be minimal on an otherwise healthy individual," he said.

Snap Fitness Kawana manager Scott Hammell said his gym was hesitant about restocking pre-workout supplements including Jack3d because of its uncertain future.

Another Coast supplement supplier, who asked not to be named, said it was an overreaction.
