250 ml Red Bull. 500 ml Monster. A pre-workout. A gaming booster. Anyone active in the gaming scene, in their studies, or working shifts knows these quantities. And anyone who knows them also knows what comes next: trembling, racing heart, tingling, a mind that can't rest.
Energy drinks affect you differently than coffee. This isn't imagination – it's chemistry.
Why Energy Drinks Have a More Intense Effect Than Coffee
An espresso contains 60–80 mg of caffeine. A 250 ml can of Red Bull contains 80 mg – sounds comparable. But the difference isn't just in the caffeine.
1. Sugar + Caffeine: The Dopamine Rush Combo
Energy drinks often contain 25–30 g of sugar per can. Sugar triggers an insulin surge that provides short-term energy – and then abruptly drops. Combined with caffeine-induced adrenaline, this creates a stronger and more abrupt peak-and-crash effect than with coffee.
2. Taurine: Misunderstood and Overestimated
Taurine, on its own, has rather calming properties. However, in combination with high amounts of caffeine and sugar, it can amplify cardiovascular effects.
3. Rapid Absorption Due to Liquid Form
Liquid caffeine sources are absorbed more quickly. The caffeine peak comes faster and more steeply – and with it, the side effects.
The Most Common Symptoms After Too Many Energy Drinks
Trembling and Tingling
A slight tremor in the hands, sometimes a tingling sensation in the lips or fingers. This is a direct consequence of adrenaline release and muscular overstimulation by caffeine.
Racing Heart and Irregular Pulse
Multiple 500 ml cans of energy drink can raise the heart rate to 120 beats per minute and more – even without physical activity. It is almost always harmless but feels dramatic.
Anxiety and Panic Attacks
High doses of caffeine can trigger genuine anxiety reactions – racing heart + tingling + shortness of breath. The brain interprets the body's signal as a threat, creating a vicious cycle.
The Crash
After 2–4 hours, energy collapses. Adenosine floods the brain, sugar is depleted, the body is exhausted. Many then reach for the next can – starting the cycle all over again.
Stomach Problems
The combination of caffeine, sugar, and acid in energy drinks is a sure recipe for stomach problems: heartburn, nausea, sometimes cramps. Especially on an empty stomach.

When You Should Stop and See a Doctor
Heart palpitations that last longer than an hour. Chest pain or shortness of breath. Loss of consciousness or pre-stages thereof. More than 400 mg of caffeine daily (equivalent to about 5 cups of coffee or 5 cans of Red Bull). EFSA recommends a maximum of 400 mg of caffeine per day for healthy adults.
Conclusion: You Don't Have to Choose Between Performance and Well-being
Energy drinks are not the problem – uncontrolled side effects are. With the right balance, you can reap the benefits and minimize the downsides.
