Energy Drinks for Children and Teens: Caffeine, Sugar, a Clear No
Energy drinks and children: the answer is no, all the way to 18. A single can can hold as much caffeine as two cups of coffee, plus 6 or more teaspoons of sugar, and a child’s smaller body feels both far more strongly than an adult’s. Racing heart, shaky hands, broken sleep, headaches when they stop. Exam week makes it tempting. It still doesn’t work the way teenagers think it does. Here’s what’s inside the can, what it does to a growing body, and what to hand them instead.
The short version
- Under 18: no energy drinks, including “sugar-free” ones.
- Caffeine per can: often about 80 mg in 250 ml, up to around 160 mg or more in large cans.
- Sugar per can: roughly 6 to 7 teaspoons in 250 ml, double that in 500 ml.
- Adults: 400 mg caffeine a day from all sources; 200 mg in pregnancy.
- Emergency signs: chest pain, fainting, a fit, a heartbeat that won’t settle.

Why energy drinks are a clear no for children
Caffeine works the same way in a 12-year-old as in a 40-year-old, blocking the brain’s “time to rest” signal so the body keeps revving when it should be winding down. The difference is size. A 35 kg child drinking one can gets roughly double the caffeine per kilo that a 70 kg adult gets, and children who don’t drink much chai or coffee have no tolerance at all.
That’s why a can that makes an adult feel alert can make a child’s heart pound, hands shake and stomach churn. Some children, including those with heart rhythm conditions nobody has diagnosed yet, can have dangerous rhythm problems after large amounts. Rare. Not worth it.
A can that wakes an adult up can wind a child’s heart up.
By age
- Under 6 months to 3 years: no caffeine at all. Milk and water only (and nothing but breast milk or formula under 6 months).
- 3 to 6 years: no energy drinks, no cola as a habit, no strong chai.
- Over 6, including teens: no energy drinks. If caffeine comes at all, it’s from a small cup of weak chai. Health Canada suggests children keep total caffeine to around 2.5 mg per kg of body weight a day at most, and one can blows past that for most kids.

What’s actually in the can
| Ingredient | Typical amount | What it does |
|---|---|---|
| Caffeine | About 32 mg per 100 ml | Alertness, racing heart, poor sleep |
| Sugar | About 11 g per 100 ml | Quick spike, then a slump |
| Guarana | Varies | More caffeine, often not added to the total |
| Taurine, B vitamins | Varies | Label decoration; no energy of their own |
Read the back of any can. The caffeine line is usually given per 100 ml, so multiply by the can size: a 500 ml can at 32 mg per 100 ml is 160 mg. The cheap bottled “booster” and “power” drinks sold at every kiryana store belong to the same class, whatever the colour or the price, and some come in even bigger bottles.
Energy drink side effects for teens
- Heart: palpitations, a fast pulse, a temporary rise in blood pressure.
- Sleep: caffeine lingers for hours. A can at 5 pm is still working at midnight.
- Mood: jitteriness, anxiety, irritability, and a crash when it wears off.
- Stomach: acidity, nausea, loose stools.
- Teeth: sugar and acid together soften enamel.
- Withdrawal: headaches and tiredness on days without, which pushes the next can.
Mixing energy drinks with other caffeine (coffee, cola, pre-workout powders) stacks the dose. So does drinking two or three cans during an exam night or a gaming session.
Sugar, weight and diabetes risk
A 250 ml can carries about 27 g of sugar, close to 7 teaspoons, and a 500 ml can double that, which for a teenager having one most afternoons adds up to a lot of liquid sugar that doesn’t fill them up, so dinner gets eaten on top of it anyway. Regular sugary drinks are a well-known driver of weight gain and type 2 diabetes risk, which is now showing up in young people too. “Sugar-free” versions drop the sugar and keep the caffeine, so they aren’t a child-safe swap.

Myth: energy drinks help you study
A tired brain on caffeine feels awake. It doesn’t learn better. Memory is laid down during sleep, so a can that buys two extra hours of cramming and costs three hours of deep sleep is a bad trade the night before a paper. Sleep, short breaks, a real meal and water do more for exam marks than any can.
Energy drink for a breastfeeding mom
Caffeine passes into breast milk in small amounts, and because a young baby’s liver is still learning to break it down, a newborn can take many times longer than an adult to clear the same caffeine, so it builds up across a day of cups and cans. Keeping to the lower pregnancy-level mark of 200 mg a day from all sources is a cautious target while breastfeeding, counting chai and coffee too. If the baby seems unusually fussy or sleeps badly, cut back. An energy drink’s sugar adds nothing a nursing mother needs; water, milk and a proper meal do far more for tiredness.
What to give instead
- Keep a 1 litre bottle of water in the fridge or school bag, and refill it once.
- Offer a glass (about 200 ml) of plain doodh or a small lassi with a snack after school.
- Pack a piece of fruit, a handful of roasted chana, or a boiled egg for sport or long study.
- For a match over an hour in the heat, water plus a banana at half time.
- Set a caffeine cut-off: nothing caffeinated after 2 pm for older teens who do drink chai.

Call for emergency help if a child or teen has chest pain, faints, has a fit, is confused, or has a pounding heartbeat that doesn’t settle after resting. If a young child has drunk a whole can, or several, go to hospital and take the can. Teens with a heart condition, fainting history, ADHD medicine, anxiety or high blood pressure should avoid caffeine drinks entirely and talk to their doctor.

Energy drink questions parents ask
What to do if a child drinks an energy drink?
One can in an older child usually causes jitters and poor sleep, then passes. Give water, keep them calm, and seek help for chest pain, fainting, vomiting or a racing heart that won’t settle.
Are energy drinks bad for you?
For adults, occasional cans within the 400 mg daily caffeine limit are a sugar and sleep problem more than a danger. For children and teens, yes, they’re not suitable.
At what age can you drink energy drinks?
Not before 18. Even then, count every can towards the adult daily limit.
Is a sugar-free energy drink OK for kids?
No. It still has the full caffeine load, which is the main problem for children.
Can children have energy drinks during a fever?
No. Caffeine and sugar don’t help a feverish child. Offer water, milk, or ORS if drinking little; see a doctor for a fever of 39 °C or over 3 days.
Is there a healthy energy drink for kids?
Water, milk and fruit. Anything sold as an energy drink is a no for children.
How much caffeine is in an energy drink?
Commonly about 80 mg in a 250 ml can and 160 mg or more in a 500 ml can. The label gives it per 100 ml.
Can energy drinks raise blood pressure?
Yes, for a few hours. That matters more for anyone who already has high blood pressure or a heart condition.
Is a homemade energy drink for kids safe?
If it’s nimbu pani with a little sugar and a pinch of salt, or a banana lassi, yes. Skip anything with coffee, green tea or “energy” powders.
Can a breastfeeding mom drink an energy drink?
An occasional one within about 200 mg of caffeine a day, counted with chai, is a cautious limit. Watch the baby for fussiness or poor sleep.
