The caffeine content is 80mg for a 8.4oz can of Red Bull. Compare that to 96mg of caffeine in an 8oz cup of coffee according to the USDA Food Data website.
How about a 16oz can of Monster Energy? 160 mg of caffeine! But notice that even though the caffeine content is double, so is the size of the drink. So the caffeine content per oz is almost the same as the Red Bull.
