The medical community is raising questions regarding athletes using performance-enhancing stimulants in light of recent evidence that has emerged from a marathoner’s death.
While running a city marathon last April, Claire Squires, who was an otherwise healthy 30-year-old runner, collapsed near the Buckingham Palace and died due to heart failure. She was running to raise awareness and money for an organization that helps to prevent suicides, and had inspired over $1 million in donations.
A coroner’s report has released evidence that says the energy supplement Squires consumed during the race, Jack3D, contributed to the runner’s heart failure.
Jack3D, which features the stimulant dimethylamylamine (DMAA), was in fact banned in England four months after Squires death because it was found to be too dangerous.

"DMAA ... on the balance of probabilities, in combination with extreme physical exertion, caused acute cardiac failure, which resulted in her death," said coroner Philip Barlow.
"Claire was passionately against the use of drugs and would never, ever, have taken anything that would have caused her harm or even worse risked her life," Squires' partner Simon Van Herrewege told the Daily Mail. "She innocently took a supplement which at the time was entirely legal, and widely available on the high street, and somewhat worryingly, apparently used by so many others."
Overseas in America, the Food and Drug Administration is investigating other deaths that may have been linked to different energy drinks and supplements, specifically 5 Hour Energy and Monster Energy. The FDA suspects that 14 deaths over the past four years could be attributed to 5 Hour Energy.
