Monster Energy Zero Ultra is a zero sugar, zero calorie energy drink delivered in a light, refreshing citrus flavor. This Costco value pack includes 12 resealable 24 fl oz white cans, providing a total of 288 fl oz of the popular Zero Ultra variety. Each large-format can features a resealable cap, so you can enjoy part of the drink and seal the rest for later.

Each 24 fl oz can contains 210mg of caffeine along with the signature Monster Energy Blend of taurine, panax ginseng extract, L-carnitine, guarana extract, glucuronolactone, and inositol. The drink is sweetened with erythritol, sucralose, and acesulfame potassium—delivering the full Monster flavor experience without any sugar. The light sparkling citrus profile makes Zero Ultra one of Monster's most sought-after flavors for those who prefer a less sweet, highly drinkable energy drink.
