How much is too much? Up to 400 milligrams (mg) of caffeine a day appears to be safe for most healthy adults. That's roughly the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two energy shot drinks. Although caffeine use may be safe for adults, it's not a good idea for children. And adolescents should limit themselves to no more than 100 mg of caffeine a day.
Drinking 400 milligrams of caffeine (the equivalent of four 8-ounce cups of coffee) is considered safe by most physicians. However, energy drinks can contain as much as 1200 mgs of caffeine â an amount three times higher than what is generally considered acceptable. This overload of caffeine is then âturbo-chargedâ with the addition of natural stimulants like Guarana and Yerba Mate in certain energy drinks.
