Is 15 coffees a day bad?
For most adults, the FDA has cited 400 milligrams* a day — that’s about two to three 12-fluid-ounce cups of coffee — as an amount not generally associated with negative effects. However, there is wide variation in both how sensitive people are to the effects of caffeine and how fast they eliminate it from the body. There are guidelines for children ages 12 to 18 that suggest a limit of 100 milligrams of caffeine per day, which is about two cans of soda or eight ounces of coffee. Adults should limit caffeine intake to 400 milligrams, which is about two to three cups of coffee a day.Extremely high daily intakes of 1,000 mg or more per day have been reported to cause nervousness, jitteriness and similar symptoms in most people, whereas even a moderate intake may lead to similar effects in caffeine-sensitive individuals.Up to 400 milligrams (mg) of caffeine a day seems safe for most adults. That’s about the amount of caffeine in four cups of brewed coffee, 10 cans of cola or two energy shot drinks. Keep in mind that the caffeine content in drinks varies widely.
