Marathon runner who collapsed and died took now-illegal supplement

A London Marathon runner who collapsed and died near the end of the race by Buckingham Palace took a dietary supplement that might have contributed to her death, a Southwark coroner reports. Claire Squires had the stimulant Jack3D, which contains dimethylamylamine (known as DMAA), in her drinking water, according to the report. DMAA was recently banned by the World Anti-Doping Agency, but was legally available to the public in England before August of 2012. Marathon officials say they only asked that runners be medically fit to participate in the race. But following the coroner's findings, they'll update medical advice to include notes about supplements.
