London, Aug 7: A new trend gaining traction among teenagers in the US and potentially creeping into the UK is setting off alarm bells among health experts — caffeine pouches. These teabag-like products, discreetly tucked between the lip and gum, offer a direct hit of caffeine to the bloodstream, delivering an instant energy boost. But the seemingly harmless fad has left nutritionists and doctors deeply worried.

According to experts, a single pouch may pack the punch of up to two cups of coffee, raising the risk of overconsumption and associated side effects. While marketed on social media platforms like TikTok as a tool for gym-goers or students looking to stay sharp, experts fear the flashy flavours and influencer endorsements are luring teens into a potentially dangerous habit.

Dr Rob van Dam of George Washington University notes that the pouches' discreet nature makes them easier to hide from parents and teachers, potentially leading to unsupervised and excessive use. Alarmingly, some users even boast online about using two pouches at once to amplify the “buzz.”

Although caffeine is commonly used by athletes to boost performance — blocking the brain’s fatigue signals and dulling perceived exertion — excess intake can trigger serious health issues such as rapid heartbeat, irregular heart rhythms, seizures, and in rare cases, death.

Dr Lewis James from Loughborough University explains that while caffeine can aid physical activity, it also acts on the cardiovascular system, posing risks especially for younger users with low tolerance.

Currently, EU law mandates warning labels on energy drinks containing over 150mg of caffeine, but similar regulation around caffeine pouches is still lacking. This has raised fears of a repeat of past concerns surrounding nicotine pouches and snus — with both dentists and dietitians warning that caffeine pouches can irritate gums and potentially act as a gateway to stronger stimulants.

Bini Suresh, head of dietetics at Cleveland Clinic London, warns that caffeine may feel like a quick fix but can lead to sleep disruption and chronic fatigue — particularly harmful in growing adolescents.

“Instead of relying on stimulants, teens should focus on balanced meals, hydration, and iron- and protein-rich foods that provide lasting energy,” she advised.

With the European Food Safety Authority recommending just 3mg of caffeine per kilogram of body weight for children, experts are calling for immediate caution and regulation before the trend becomes widespread in the UK.
