How Much Caffeine Is Too Much Caffeine (cont.)

Medical Reviewer:

Most experts agree that getting more than 600 milligrams of caffeine per day is too much. "But if you are sensitive to caffeine, even one or two cups of coffee could cause side effects. Children may be very sensitive to the effects of caffeine. For pregnant women, the safe limit is only 200 milligrams," says Everett.

"You may need to be extra careful about caffeine if you have a heart condition, high blood pressure, or acid reflux disease," says Jeffers. At high enough doses, caffeine can be deadly for anyone. A lethal dose is about 10 grams, which would be about 100 cups of coffee.

"It's all about moderation. If you don't overdo it, caffeine can have some benefits. But I wouldn't recommend that you start a caffeine habit for the benefits. Remember that most of the health benefits from drinking coffee will also come from drinking decaf," says Jeffers.
