What’s in Your Energy Drink?

Energy drinks are packed with stimulants like caffeine, taurine, guarana, and ginseng, alongside sugar, vitamins, and other boosters like ginkgo biloba and carnitine. Marketed as performance enhancers, they’ve been popular since Red Bull’s 1997 debut. But while brands claim safety, research on their long-term effects, especially for adolescents, is limited.

The Dark Side: Health Risks Uncovered

Despite the hype, energy drinks can pose serious health risks. Here’s what science says: Caffeine’s kick can spike heart rate and blood pressure, potentially leading to serious issues like ventricular arrhythmias, QT prolongation, and even arterial rupture. Studies show energy drinks impair endothelial function (blood vessel health) and increase platelet activity, raising the risk of clotting.

Mind Games: Neurological and Psychological Effects

High caffeine doses can trigger anxiety, insomnia, and restlessness. In extreme cases, they’re linked to psychiatric disorders, epileptic seizures, and even hallucinations. Adolescents face higher risks, with studies showing connections to violent behaviour, conduct disorders, and ischemic stroke. Ingredients like taurine and guarana may also promote cell damage by reducing protective enzyme activity.

Gut and Metabolism: A Sugary Problem

Kidney Concerns: Renal Effects

It also increases sodium loss in urine, which can impair cardiovascular performance and reduce muscle strength. One case even linked daily energy drink use to acute kidney injury.

Smile at Risk: Dental Damage

Energy drinks aren’t all bad. Caffeine and glucose can boost memory, alertness, and mood. They’ve been shown to improve aerobic endurance, mental performance, and even driving reaction times. For example, glucose-based drinks reduce lane drifting and mental fatigue. Female volleyball players have reported better acceleration tolerance and strength.
