CASE warns teenagers about the health risks of combining energy drinks with other caffeinated beverages such as coffee or matcha, after testing showed very high caffeine levels in a common mix. One tested combination of Monster, Red Bull and espresso contains 282.1mg of caffeine, which is described as roughly equivalent to about three cups of brewed coffee.

The Straits Times reports that the same type of mixture can reach nearly three times a recommended daily limit for young people, depending on the guideline used. Channel NewsAsia similarly highlights the measured caffeine content and frames the warning around teens who may drink multiple caffeinated products to stay alert. Across both outlets, the focus is on caffeine intake exceeding recommended thresholds and the potential for excessive consumption when energy drinks are mixed with coffee-based drinks.
