Red Bull sugar-free products contain the same functional ingredients as Red Bull Energy Drink (caffeine, taurine and some B-group vitamins) but are made with non-caloric sweeteners instead of sugars. The sugars, sucrose and glucose, have been replaced by the sweeteners sucralose and acesulfame potassium. It's all about choice. Some Red Bull Editions are also available without sugars. Same wiiings and same fantastic flavors, just sugar-free.
