Do you drink just a cup of coffee or tea first thing in the morning, hoping that the caffeine will help you start your day? Do you follow it up with one or two caffeinated drinks and then drink several more cups of coffee throughout the day?

does it matter?

according to fda scientists, caffeine can be part of a healthy diet for most people, but too much caffeine can pose a danger to your health. depending on factors such as body weight, medications you may be taking, and individual sensitivity, “too much” can vary from person to person.

learn more about caffeine in the following questions and answers.

1. what types of food and drinks contain caffeine?

caffeine can be found naturally in the plants we use to make coffee, tea, and chocolate. It is also found in some plants used as flavoring, such as guarana, or alternative teas popular in South America, such as yerba mate (ilex paraguariensis) and ilex guayusa.

caffeine can also be added as an ingredient to foods and beverages.

2. How do you know how much caffeine is in a food or drink?

Many packaged foods, including caffeine-containing beverages and dietary supplements, voluntarily provide information on the label about the amount of caffeine they contain. consumers should exercise caution when consuming a new packaged food that contains added caffeine for the first time if the amount of caffeine in the food is not declared on the label.

There are several online databases that provide estimates of the caffeine content of certain foods and beverages, such as coffee and tea. however, the amount in these brewed beverages can vary based on factors such as how and where the coffee beans and tea leaves were grown and processed, and how the beverage was prepared.

for reference, a 12-ounce can of a caffeinated soft drink typically contains 30 to 40 milligrams of caffeine, an 8-ounce cup of green or black tea 30 to 50 milligrams, and an 8-ounce cup of coffee close to from 80 to 100 milligrams. the caffeine in energy drinks can range from 40 to 250 mg per 8 fluid ounces.

3. If a coffee or tea says “decaffeinated”, does that mean it is caffeine free?

no. Decaffeinated coffees and teas have less caffeine than their regular counterparts, but still contain some caffeine. for example, decaffeinated coffee typically has 2 to 15 milligrams in an 8-ounce cup. if you react strongly to caffeine in a negative way, you may want to avoid these drinks altogether.

4. how much caffeine is too much?

for healthy adults, the fda has cited 400 milligrams a day (which is equivalent to about four to five cups of coffee) as an amount not generally associated with dangerous negative effects. however, there is a wide variation in both how sensitive people are to the effects of caffeine and how quickly they metabolize (break down) it.

Certain conditions tend to make people more sensitive to the effects of caffeine, as do some medications. In addition, if you are pregnant, trying to become pregnant, or breastfeeding, or have concerns about another condition or medication, we recommend that you speak with your health care provider about whether you need to limit your caffeine intake.

The FDA has not set a level for children, but the American Academy of Pediatrics advises against caffeine and other stimulants in children and adolescents.

5. How do you know if you have consumed more caffeine than you can tolerate?

Excessive caffeine intake can cause:

  • insomnia
  • nerves
  • anxiety
  • fast heart rate
  • upset stomach
  • nausea
  • headache
  • a feeling of unhappiness (dysphoria)
  • 6. Does caffeine pose a health hazard?

    The FDA estimates that toxic effects, such as seizures, may be seen with a rapid intake of about 1,200 milligrams of caffeine, or 0.15 tablespoons of pure caffeine.

    Pure and highly concentrated caffeine products pose a significant threat to public health and have contributed to at least two deaths in the United States in recent years. (In April, the FDA took action to protect consumers of these products.)

    Often labeled as dietary supplements, these products consist of pure or highly concentrated caffeine in powdered or liquid form and are often marketed in bulk containers with up to thousands of servings per container, requiring the manufacturer to consumer to measure out a safe portion of what can be a toxic or even lethal amount of bulk product.

    The risk of caffeine overdose increases as the concentration of caffeine in the product increases, which means that even small doses of a highly concentrated product could cause dangerous effects. Just one teaspoon of pure caffeine powder can contain the same amount of caffeine as 28 cups of coffee, and a half cup of a highly concentrated liquid caffeine product contains the equivalent of more than 20 cups of coffee. these are toxic amounts that can have serious health consequences, including death.

    7. Is it okay for children to consume caffeine?

    We recommend that you consult your health care provider for advice on your child’s caffeine intake.

    8. Is drinking a lot of caffeine a sleep substitute?

    no. Caffeine is a stimulant, which can make you more alert and awake, but it is not a substitute for sleep. Typically, it can take your body 4-6 hours to metabolize half of what you consumed. therefore, a cup of coffee with dinner can keep you awake at bedtime.

    9. How can I reduce my caffeine intake without causing unpleasant side effects?

    If you’re used to drinking caffeinated beverages every day and want to cut back, it’s best to cut back gradually. stopping abruptly can cause withdrawal symptoms such as headaches, anxiety, and nervousness. Unlike opiate or alcohol withdrawal, caffeine withdrawal is not considered dangerous, but it can be unpleasant. you may want to talk to your health care provider about cutting back.
