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.
Caffeine is classified by the Food and Drug Administration as âgenerally recognized as safeâ (GRAS). Toxic doses are usually considered anything over 10 grams per day for an adult. To put that into context, one cup of coffee contains 80â175 milligrams of caffeine depending on the bean and preparation method. So someone would need to have roughly 50â100 ordinary cups of coffee to reach a lethal dose and have a true caffeine overdose.
