A large Charged Lemonade contains 390 milligrams — nearly the 400-milligram daily maximum of caffeine that the Food and Drug Administration says healthy adults can safely consume. The legal complaint called Charged Lemonade a "dangerous energy drink" and argues that Panera failed to adequately warn consumers about its ingredients, which also include guarana extract, another stimulant. The caffeine content of Panera's Charged Lemonade has always been listed in-store, Panera said. Katz had gotten a large Charged Lemonade hours before she died, and had had at least one Charged Lemonade in the days prior, according to Victoria Rose Conroy, Katz's roommate and close friend. Crawford said if Charged Lemonade is going to remain on the menu, it should be less accessible to customers.
