There is no single caffeine limit accepted by every health authority for all children and teenagers. Health Canada recommends no more than 2.5 milligrams per kilogram of body weight per day for people up to age 18; the European Food Safety Authority (EFSA) proposes 3 mg/kg per day as a safety level for habitual intake by children and adolescents. These are authority-specific reference levels, not goals to consume. For children and teens, the FDA relays medical experts’ advice against energy drinks.
What are the recommended caffeine limits for children and teens?
The numbers differ because they come from different authorities and frameworks. Neither should be treated as a universal U.S. standard or as a recommended daily serving.

| Authority and scope | Reference amount | How to interpret it |
|---|---|---|
| Health Canada: children and adolescents up to age 18 | Maximum of 2.5 mg per kilogram of body weight per day | Health Canada’s recommended maximum daily intake. Health Canada guidance. |
| European Food Safety Authority (EFSA): children and adolescents | 3 mg per kilogram of body weight per day | A proposed safety level for habitual consumption, based on EFSA’s 2015 scientific assessment and summarized on its caffeine topic page. |
The values should not be blended or treated as though one automatically replaces the other. Both use body weight: multiply a child’s weight in kilograms by the relevant authority’s figure to calculate that authority’s reference amount. This arithmetic does not make the result a target, and a daily total below either reference is not a guarantee that caffeine will cause no effects.
Health Canada notes that healthy older and heavier adolescents aged 14–18 may be able to consume caffeine similarly to healthy adults. That observation does not erase its stated recommendation for people up to age 18 or establish that the same intake is appropriate for every teenager.

Why a reference amount is not a daily goal
Caffeine affects people differently. Sensitivity, health conditions, medicines, the amount consumed at once, and the time of day can all matter. EFSA notes that around 1.5 mg/kg may affect sleep duration in some children and adolescents, particularly when consumed close to bedtime. That is an observed sleep concern, not a separate daily limit.
For practical decisions, less caffeine—and avoiding it, especially late in the day—is preferable to trying to use up a calculated maximum. If a child has a health condition, takes medication, or has symptoms after caffeine, ask their clinician for advice specific to them.

Are energy drinks safe for children and teens?
FDA consumer guidance says medical experts advise against energy drinks for children and teens. Health Canada says children should not consume caffeinated energy drinks; its labeling information includes the warning “Not recommended for those under 14 years old.” That label warning is not permission for older teens to use these drinks.
The American Academy of Pediatrics’ 2011 clinical report said, “Stimulant-containing energy drinks have no place in the diets of children or adolescents.” The AAP page identifies that report as retired in July 2021, so the sentence is historical report wording, not a current standalone policy statement. See the FDA consumer update and Health Canada’s energy drink guidance.

How to count caffeine across a day
Caffeine can come from more than coffee. It occurs naturally in tea, chocolate, kola, guarana, and yerba mate, and manufacturers can add it to foods and drinks. Soft drinks and other packaged products may contribute too. Check the ingredient list for sources such as guarana or yerba mate, not just the product name.
- Check the amount per serving. Use the label’s caffeine amount where provided, and note how many servings the child actually drinks or eats.
- Compare serving size with container size. A package may contain more than one serving; consuming the whole container can mean more caffeine than the per-serving figure suggests.
- Add sources consumed throughout the day. Include drinks, chocolate, and any foods or supplements with caffeine rather than counting only coffee or tea.
- Consider timing as well as the total. A quantity that appears modest against a daily reference can still interfere with sleep, especially near bedtime.
Caffeine amounts vary by product and serving size. The FDA and AAP materials provide practical context for why a familiar beverage name or container size is not enough to estimate intake; see the AAP parent resource.

What effects can too much caffeine cause?
The FDA lists increased heart rate, heart palpitations, high blood pressure, anxiety, sleep problems, digestive problems, and dehydration among possible effects of too much caffeine in children and teens. These effects are reasons to reduce or avoid caffeine and seek medical advice when appropriate, not a checklist for deciding that an amount is safe.
