Youth Caffeine Regulations Around the World

Written by Eunseo Whaong

Why Regulate Teen Caffeine Consumption?

Teenagers have lower body weight and a slower caffeine metabolism compared to adults, which increases the risk of side effects.
These can include heart palpitations, anxiety, sleep disturbances, and reduced concentration.
For this reason, some countries have implemented policies such as age-based sales restrictions, mandatory warning labels, and advertising regulations.

Country-by-Country Overview

At-a-Glance Comparison

What’s Behind These Numbers?

Looking at this chart, you can see how each country takes a different approach to youth caffeine consumption. In South Korea, you won’t find high-caffeine drinks in school stores, while the UK’s big retailers won’t sell energy drinks to anyone under 16. The U.S. leaves it mostly up to each state, so rules can vary a lot. Canada stands out with clear age-based recommendations, and Australia/New Zealand keep things strict with an official caffeine cap per drink. On the other hand, Japan is more relaxed—there’s no sales restriction, but labels must show caffeine content.

Conclusion

Global teen caffeine regulations range from strict legal enforcement to voluntary guidelines.
However, a common trend is increasing awareness of the risks and expanding measures such as school sales bans and warning labels in major retail channels.
