Monster Nitro refers to Monster Nitro Super Dry, an energy drink that uses nitrous oxide for a smooth, creamy, and “dry” texture and a citrus flavor. It contains a classic Monster energy blend, including caffeine, taurine, and B-vitamins, to provide an energy boost. The drink is packaged in 16-ounce cans and has a unique, light, and fizzy feel similar to fine champagne.
