Monster® Energy Drink Zero Ultra. Zero sugar. Zero calories. 16 fl oz (473 ml). Some people are impossible to please. As soon as they get what they thought they wanted they always want more. Our team riders and Monster girls are no different...they've been dropping some hints lately. They've been asking us for a new Monster Drink. A little less sweet, lighter-tasting, zero calories, but with a full load of our Monster Energy blend. Sure, white is the new black, we want all out: Monster Energy Zero Ultra. Unleash the ultra beast! Caffeine from all sources: 70mg per 8 fl.oz. serving (140 mg per can). www.monsterenergy.com. © 2012 Monster Energy Company.
