How Much Caffeine is there in a Red Bull?

Red Bull contains 148mg of caffeine per can

This is rather typical for energy drinks on the market, and translates to 9.2mg/fl oz or 30mg/100ml. This is comparable to other drinks like Monster Energy, but is actually behind popular competitors like Ghost (200mg/can).

Do note that Red Bull comes in several serving sizes, usually 8.4 fl oz (258g), 12 fl oz (369g) and 16 fl oz (492g). As is common with many energy drinks, Red Bull contains a range of other stimulants other than caffeine, all purported to give you wings.

For reference, a Starbucks Espresso contains 150mg of caffeine in a single serving.

Is it safe to consume that amount of caffeine?

The US Food and Drug Administration (FDA) recommends a maximum daily intake of 400mg of caffeine per day for healthy adults. These guidelines vary for children (100mg/day) and pregnant women (200mg/day).

The bottom line is, you should be fine as long as you don't go overboard. Keeping in line with health awareness trends, Red Bull also offers a zero sugar product which could help dial back on the calories, but take note that the caffeine intake is still there.

I need a boost but I don't have a can!

That iconic blue and silver can of Red Bull is not always on-hand when you need it the most. You could be driving, in class or at a meeting, where it would be a no-no to crack one open and gulp down.
