Panera Bread Charged Lemonade drinks

The announcement comes in the wake of ongoing controversy around energy drinks sold by Panera Bread, which has been linked to multiple deaths thanks to its high caffeine content, according to multiple lawsuits.

The Charged Lemonades, a set of highly caffeinated drinks in multiple flavors, have been accused of causing serious physical harm to customers who consumed them, even allegedly resulting in death. Two lawsuits, filed in October and December of last year, allege the drink's caffeine contents caused the cardiac arrests that killed two separate people, while a third filed this year alleges the beverage caused permanent heart issues.

While warnings about the product have since been added in-store and online by the company, the drinks are still available for purchase. Recently, Panera's request to dismiss one of the suits was denied by a judge, a sign these cases may take some time to move through the courts.
