According to scientists at the U.S. Food and Drug Administration, caffeine can be part of most people's healthy diets, but too much caffeine can be a threat to your health.
Caffeine can occur naturally in the plants we use to make coffee, tea, and chocolate. It is also found in some plants used as a condiment, such as guarana, or in alternative teas popular in South America, such as yerba mate (Ilex paraguariensis) and Ilex guayusa.
Caffeine can also be added as an ingredient in foods and beverages.
Can children drink energy drinks that contain caffeine?Many packaged foods, including beverages and dietary supplements that contain caffeine, voluntarily provide information about their caffeine content on the label. Consumers should be cautious when consuming new packaged food containing caffeine for the first time if the caffeine content is not declared on the label.Energy drinks contain more than twice as much caffeine as the same amount of coffee. According to the American Academy of Pediatrics, "there is a heightened awareness of the risks of use, abuse, and even toxicity in children and adolescents." * Talk to your health care provider about recommendations for your child's caffeine intake.

There are several 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 depending on factors such as how and where coffee beans and tea are grown and processed, as well as how the beverage product is prepared.
For reference, a 354ml can of caffeinated soft drink typically contains 30 to 40 mg of caffeine, a 236ml cup of 30-50 mg of green tea or black tea, and a cup of close to 80 to 100 mg of 236ml of coffee. The caffeine content in energy drinks is 236-40 mg per 250ml.
No. Decaf coffee and tea have less caffeine than regular caffeine, but they still contain some caffeine. For example, decaf coffee typically contains 15-8 mg in a 60ml cup. If you have a strong reaction to caffeine, you may want to avoid these drinks altogether.
For healthy adults, a dose of 400 mg (about four to five cups of coffee), as this amount is not usually associated with dangerous negative effects. However, there is a wide variation in how sensitive people are to the effects of caffeine and how quickly they metabolize (breakdown) caffeine.
Certain conditions tend to make people more sensitive to the effects of caffeine, as do certain medications. Additionally, if you are pregnant, trying to conceive, or breastfeeding, or are concerned about other medical conditions or medications, we recommend that you consult your healthcare provider to see if you need to limit your caffeine intake.
Levels have not been set for children, but children and adolescents are discouraged from ingesting caffeine and other stimulants.
Excessive caffeine intake can lead to:
Insomnia. Up tight.
Anxiety. The heart rate is fast.
Upset stomach. Disgusting.
Headache. Feelings of unhappiness (irritability).
The U.S. Food and Drug Administration estimates a quick intake of about 1,200 mg of caffeine or 0Toxic effects, such as seizures, can be observed with 15 tablespoons of pure caffeine.
Pure and highly concentrated caffeine products pose a significant threat to public health and are responsible for at least two deaths in the United States. The U.S. Food and Drug Administration has taken action to protect consumers from these products.
These products, often labeled as dietary supplements, consist of pure caffeine or highly concentrated caffeine in powder or liquid form, and are often sold in bulk packages, with up to thousands of servings per container, requiring consumers to weigh safe portions from potentially toxic or even deadly bulk products.
As the concentration of caffeine in a product increases, so does the risk of caffeine excess, which means that even small doses of highly concentrated products can lead to dangerous effects. Just one teaspoon of pure powdered caffeine can contain the equivalent amount of caffeine in 28 cups of coffee, while half a cup of liquid high-strength caffeine product contains the same amount of caffeine as more than 20 cups of coffee. These are toxic amounts that can have serious health consequences, including death.

No. Caffeine is a stimulant that may make you more alert and awake, but it is not a substitute for sleep. Normally, it can take 4 to 6 hours for your body to metabolize half of what you consume. So, having a cup of coffee at dinner may keep you awake before bed.
If you're used to drinking caffeinated beverages every day and want to cut back on them, it's best to take it a step at a time. Abrupt cessation can lead to withdrawal symptoms such as headaches, anxiety, and nervousness. Unlike opioid or alcohol withdrawal, caffeine withdrawal is not considered dangerous, but it can be unpleasant. You may need to talk to your healthcare provider about how you can reduce your expenses.
