How much caffeine is too much?

The FDA recommends that healthy adults consume 400 mg per day. This is equivalent to four to five cups of coffee. It is not associated with any dangerous or negative side effects. There are many factors that can affect how sensitive individuals are to caffeine, and how quickly they break it down.
Some medications and certain conditions can make people more sensitive than others to the effects of caffeine. We recommend speaking to your doctor if you are pregnant, planning to become pregnant, breastfeeding, or have any other concerns about caffeine.
Although the FDA has not established a minimum level for children, the American Academy of Pediatrics strongly discourages children and adolescents from consuming stimulants such as caffeine.

How can you tell if you have taken more caffeine than your body can handle?

Caffeine intake can lead to:
Fast heart rate
Symptoms of upset stomach
Dysphoria is a feeling of sadness or unhappiness.

Does "decaffeinated" refer to a cup of coffee or tea that does not contain caffeine?

No. Decaf coffees or teas may contain less caffeine than their regular counterparts but still contain some caffeine. Decaf coffee has typically is between 2-15 mg per 8-ounce glass. These beverages may be harmful if you are sensitive to caffeine.

Treatment for caffeine overdose

The treatment is intended to reduce the effects of caffeine and help you manage your symptoms. You may be prescribed carbon, which is often used to treat drug overdoses. This helps prevent the caffeine from getting into your gastrointestinal tract.
You might be offered a laxative if caffeine has already reached your gastrointestinal tract. Gastric lavage involves the use of a tube to remove any contents from your stomach. Your doctor will probably choose the most efficient method to get the caffeine from you. During this time, your heart rate and rhythm will be monitored using an EKG. Sometimes, you might also need breathing support.
Home treatment might not always be effective in accelerating your body's caffeine metabolism. If you aren't sure if treatment is necessary, contact your nearest medical center for professional assistance.

How can you determine how much caffeine is in a beverage or food?

Many packaged foods, including drinks and dietary supplements, include information on the labels about how much caffeine they contain. If the caffeine content is not listed on the label, consumers should be cautious when they consume a new packaged food that contains caffeine.
Many online databases provide estimates of the caffeine content of various foods and beverages, such as tea and coffee. The amount of caffeine in these brewed beverages will vary depending on many factors, including where and how the tea leaves and coffee beans were grown.
A 12-ounce caffeinated soft drink can typically contain 30-40 mg of caffeine. An 8-ounce cup of green or black tea contains between 30-50 mg, and an 8-ounce coffee cup has 80-100 milligrams. Energy drinks contain between 40 and 250 mg of caffeine per eight fluid ounces.
