NOS

NOS Energy Drink is an energy drink sold in 16 and 24oz cans. The drink was also once distributed in a bottle designed to look like a NOS (Nitrous Oxide Systems) tank, which was discontinued in 2015. Formerly a property of The Coca-Cola Company, it is currently produced by Monster Beverage and licensed by Holley Performance, which owns the trademark. NOS contains high levels of taurine and caffeine, and it also contains guarana. L-Theanine was removed as a "CMPLX6" ingredient in 2016, with inositol becoming listed as one of the six featured ingredients on the can. NOS Energy is currently available in Original, Sugar Free, Charged Citrus, Cherried Out, GT Grape, Rowdy, and Nitro Mango.
