SAN DIEGO (AP) -- Parents of a soldier who died after taking a dietary supplement called Jack3d (pronounced 'jacked') have sued the makers and retailer for wrongful death.
U-T San Diego (http://bit.ly/VVvCYL ) says Michael Sparling's family sued Wednesday in San Diego.
Sparling died of a heart attack in 2011 after collapsing during physical training at the Army's Fort Bliss in Texas. He'd been taking Jack3d before workouts.
The supplement contains DMAA, which the suit claims can cause heart problems.
The military pulled the supplement from its store shelves after Sparling and another soldier died.
U-T San Diego says the supplement maker, USPLabs, and the ingredient producer, San Marcos-based Natural Alternatives International, didn't immediately respond to comment requests. Retailer GNC said it doesn't comment on pending litigation.
