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.
To best minimize your risk, consume less than 100 milligrams of caffeine per day, or no more than 1 to 2 cups of coffee. Caffeine may also have adverse impacts in children, such as disturbing their sleep, and intake should be limited to 2.5 milligrams of caffeine per kilogram of their body weight per day.he Journal of Food Science notes that the dose at which caffeine becomes toxic to your body is difficult to establish, but may be near 10 grams per day, or roughly 100 cups of coffee.
