Personal trainer Steven Marinkovich said he does not start a workout before taking a supplement called Hemo Rage.

"It just gives me an enormous amount of energy," he said.

However, Marinkovich admits that the boost soon turns to bust.

"It's weird," he said. "It's a like a hangover afterwards where you feel kind of jittery for a while."

Hemo Rage is so potent that there is even a warning label on the lid. The powder supplement is one of 200 on the market with DMAA, or 1,3-dimethylamylamine.

DMAA is marketed as an energy booster and a weight loss aid but the Food and Drug Administration calls it a synthetic substance that can lead to major health problems.

Now, the military has banned all service members from taking the dietary supplements.

According to the "Army Times," the military worries the substance may have contributed to the deaths of two soldiers and the collapse of at least five other service members.

"This is news to me, to be honest," said Marinkovich. "It makes me a little more cautious for sure."

Several companies that manufacture DMAA are also in the FDA's crosshairs because the FDA said they did not provide evidence the products were safe.

10News found several of those companies fighting back against the FDA's claims and standing by the product's safety.

A Department of Defense spokesman said there has not been a scientific link between DMAA and the medical conditions reported by the military and that the ban is a precautionary measure until there is further information.
