Question: How much caffeine in a Red Bull?
Answer: When we think of an energy drink, a Red Bull is likely one of our first thoughts. Red Bull is the top-selling energy drink brand as of 2015 with over 40% of the market share. In total, the company has sold 60 billion cans over its lifetime.
A big reason Red Bull is considered an energy drink is because it contains a significant amount of caffeine along with B-vitamins, and the amino acid taurine. Let’s look at how much caffeine is in a Red Bull.
An 8.4 fluid ounce can of Red Bull contains 80 mg of caffeine. A coffee of the same serving size has about 100 mg of caffeine.
