NOS Energy Drink is an energy drink sometimes distributed in a bottle designed to look like a NOS cartridge. It is produced by the The Coca Cola Company, and licensed by Holley Performance, which owns the trademark. NOS is available in 8 and 16 ounce aluminum cans, 11 and 22 ounce resealable bottle forms and as a 2 ounce "Powershot." The original version is flavored with juice, but other variants including "fruit punch" and "grape" are also available. Like many other energy drinks, NOS contains high levels of taurine, and caffeine, but differs via its inclusion of large amounts L-carnitine. read more
