How much caffeine is too much? Dr. Larry weighs in

OAKLAND, Calif. (KTVU) - A 16-year-old from South Carolina collapsed and died last month after consuming too much caffeine.

Authorities say the teen drank a large Mountain Dew, a latte and an energy drink within two hours. He had no history of heart problems, however, not even a healthy heart could take the stress of the reported amount of caffeine consumed.

How much caffeine is too much?

According to our medical expert, Dr. Larry, it’s all about timing,  “400 mg of caffeine within two hours certainly is gonna have a higher level of caffeine in your system than if you spread that out with four cups of coffee, over a whole day.” A typical cup of coffee contains about 100mg of caffeine, which is harmless.

While caffeine in moderation is otherwise harmless for most people, overdoes is possible for even the healthiest of people.

If you have a heart history, or palpitations, it may be time to think twice about your caffeine intake.
