NOS

NOS is an energy drink sold in 16-and-24-US-fluid-ounce (470 and 710 mL) cans. The drink was also distributed in a bottle designed to look like a NOS (Nitrous Oxide Systems) tank but this bottle has been discontinued. 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.
