A standard 8.4 fl oz (250 ml) can of Red Bull contains about 80 mg of caffeine , which is roughly equivalent to the caffeine content in a cup of home-brewed coffee
. Larger can sizes contain proportionally more caffeine; for example:
- 12 fl oz can: approximately 114 mg of caffeine
- 16 fl oz can: approximately 151 mg of caffeine
- 20 fl oz can: approximately 198 mg of caffeine
The caffeine content may vary slightly depending on the country due to legal restrictions, but 80 mg per 250 ml is the typical amount in the original formula
. In comparison to other caffeinated beverages, Red Bull has less caffeine than a typical Starbucks coffee (which can have over 200 mg per cup) but more than black tea or a Coca-Cola can
