NEW YORK (AP) — Monster Beverage is suing San Francisco’s city attorney over demands that the energy drink maker reduce the amount of caffeine in its drinks and change its marketing practices.

The company, based in Corona (Riverside County), says it’s being unfairly singled out by City Attorney Dennis Herrera, who late last year had asked Monster to produce documentation showing that its drinks are safe. Since then, Monster says Herrera has asked it to reformulate its drinks and change its labels and marketing materials.
A representative for the city attorney’s office did not immediately return a call for comment.
The suit comes at a time when the energy drink industry has come under intense scrutiny. The Food and Drug Administration is investigating reports of deaths linked to energy drinks, although the agency has noted that the reports don’t prove the drinks caused the deaths.
New York’s attorney general has also subpoenaed Monster — as well as the maker of 5-Hour Energy shots and PepsiCo Inc., which makes Amp — as part of an investigation into how energy drinks are made and marketed. In addition, the family of a 14-year-old girl is suing Monster after they said she died after drinking two 24-ounce cans of Monster in a short period.
