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.
âA recommended target is about 1.5 mg of caffeine per pound of body weight,â says Clark, and that's the high end of sports nutrition guidelines. So if you weigh 150 pounds, that equates to 225 mg of caffeineâabout 12 to 18 ounces of coffee. A pill that contains 200 mg of caffeine is close to that target but if you've already had coffee that day, or if you take a caffeine supplement before an afternoon workout, you might be awake all night, Clark warns.
