A big chunk of a day's sugar in one serving.
A single 8.4 fl oz can of Red Bull carries about 27 g of added sugar — close to a full day's recommended limit — packed into a can smaller than a typical soda. It's paired with about 80 mg of caffeine, roughly what's in a cup of coffee, so the sugar rush and the caffeine hit land together.
Energy drinks are often reached for daily, sometimes more than once, which stacks that 27 g fast. Sugar-free versions exist and remove the sugar, but they keep the same intense sweetness and caffeine — worth checking whether it's the sugar or the buzz you actually need before reaching for a second can.
Lower-sugar swaps
- Black coffee or plain caffeine for the energy without the sugar
- Sugar-free Red Bull if you specifically want the taste and the caffeine
Frequently asked questions
- Is Red Bull worse than Coke for sugar?
- Gram for gram, yes — Red Bull's 27 g comes in a smaller 8.4 fl oz can than Coke's 39 g in 12 fl oz, so Red Bull is actually more sugar-dense per ounce.
- Does the caffeine in Red Bull make the sugar worse?
- They compound rather than cancel — caffeine doesn't offset sugar's blood-sugar spike, and the two together can make the crash feel sharper once both wear off.
