For what it's worth, a can of Red Bull has 80mg of caffeine, while a double shot of espresso has 150 mg and a 12 oz drip coffee has more like 260mg.

- Flankk 16y agoAgreed. Red Bull is not "high caffeine." The active ingredient in Red Bull is taurine. The study was on caffeine but yet they didn't isolate the drug in question. The margin of error for this experiment is at least 1/√(80) or 11%. This is science?
- hugh3 16y agoI'm sure there's lots of research out there on the effects of caffeine. A review of the literature on its short-term effects on tiredness, concentration and ability on various tasks would be pretty interesting, but a single result in isolation on some artificial test really isn't.
- silentbicycle 16y agoIt depends on the size of the can. That's IIRC the 8 oz size. There are also 12 and 20 oz cans. (Yeesh.)
- billswift 16y agoIt is still less than the same size drip coffee.
- silentbicycle 16y agoIndeed. Espresso isn't necessarily higher in caffeine than coffee, either, once volume is factored in. For that matter, a 100 mg caffeine pill may have less than a big mug of coffee. There's too much variation.
