But how much caffeine in healthy? Doctors say that teenagers shouldn't have more than 100 mg a day, which is about one cup of coffee, or about three cans of regular cola. That isn't to say that drinking three cans of cola is good for you, it contains a lot of sugar and can cause the negative effects mentioned earlier. You should also be very careful with energy drinks. Some large cans can contain over 150 mg of caffeine, which is more than the recommended daily amount for a teenager.
Remember if your heart often beats fast when you're resting and you don't have fizzy drinks or other drinks containing caffeine, you could have a medical problem. So, if you're even a little bit worried, you should go and ask the doctor to check you over.
