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.
There's general agreement that pregnant women and those trying to conceive should avoid consuming large quantities of caffeine. But after decades of controversy and conflicting evidence, there's still no consensus on how much caffeine is safe during pregnancy. To err on the side of caution, the March of Dimes advises women to limit their caffeine intake to less than 200 milligrams per day, which is about one 12-ounce cup of coffee.
