‘‘After discussions with the FDA, we have a greater appreciation for its concern about the proliferation of caffeine in the nation’s food supply,’’ said Wrigley North America president Casey Keller.

Michael Taylor, the FDA’s deputy commissioner of foods, said Wrigley’s decision to stop production for now ‘‘demonstrates real leadership and commitment to the public health.’’ He said the company made the move after a series of discussions with the agency.
