How Much Caffeine Is Too Much Caffeine (cont.)

Amounts of Caffeine in Food and Drinks

Coffee may be the most common source of caffeine, but there are a lot of other sources. Cup for cup, tea has about half as much caffeine as coffee. Other sources include colas, energy drinks, over-the-counter medicines, chocolate, gum, and some snack foods.

When it comes to the amount of caffeine in drinks, don't try to guess how much by the size of your beverage. "The amount of caffeine in coffee and tea depends on how they are brewed. Different brands can have different caffeine levels. One small energy drink could have the same amount of caffeine as a huge cup of coffee. You need to read labels," says Everett.

Here are some examples (in milligrams) of how much caffeine is in some typical foods and drinks:

  • 20 ounces Dunkin' Donuts with Turbo Shot: 436
  • 20 ounces Starbucks coffee: 415
  • 23.5 ounces Jolt energy drink: 280
  • One caplet of NoDoz: 200
  • 16 ounces McDonald's coffee: 133
  • Two Excedrin Migraine tablets: 130
  • 8.4 ounces Red Bull: 80
  • 8 ounces brewed black tea: up to 80
  • 16 ounces Snapple lemon tea: 62
  • 8 ounces brewed green tea: up to 60
  • 12 ounces Pepsi MAX: 69
  • 12 ounces Coca-Cola: 35
  • One piece of Jolt gum: 45
  • 4 ounces of Dannon coffee yogurt: 30
  • One Hershey's Special Dark chocolate bar (1.5 ounces): 20
  • One Hershey's Kiss: 1

How Much Caffeine Is Safe for You?

"Most people do not have to worry about cutting back on caffeine as long as they are staying under about 500 milligrams. That's about four cups of coffee a day," says Jeffers. According to the Food and Drug Administration (FDA), the average American consumes about 300 milligrams of caffeine per day.

Most experts agree that getting more than 600 milligrams of caffeine per day is too much. "But if you are sensitive to caffeine, even one or two cups of coffee could cause side effects. Children may be very sensitive to the effects of caffeine. For pregnant women, the safe limit is only 200 milligrams," says Everett.

"You may need to be extra careful about caffeine if you have a heart condition, high blood pressure, or acid reflux disease," says Jeffers. At high enough doses, caffeine can be deadly for anyone. A lethal dose is about 10 grams, which would be about 100 cups of coffee.

"It's all about moderation. If you don't overdo it, caffeine can have some benefits. But I wouldn't recommend that you start a caffeine habit for the benefits. Remember that most of the health benefits from drinking coffee will also come from drinking decaf," says Jeffers.
