Can you drink too much of Red Bull Energy Drink?

One 8.4 fl oz can of Red Bull Energy Drink contains 80mg of caffeine, about the same amount as in a cup of coffee. The consumption of Red Bull should conform to a person’s intake of caffeine generally.

Many authorities around the world have looked at the effects of caffeine. Health Canada scientists conducted an extensive review of the scientific literature on caffeine. Based on this review, they concluded that the general population of healthy adults is not at risk for potential adverse effects from caffeine if they limit their consumption to 400 mg per day. However, Health Canada recommends for pregnant women to limit their daily intake to 300 mg.
