Energy drinks often contain taurine, B vitamins, and guarana. But electrolytes? Almost none. Sodium, potassium, magnesium—that’s what you lose when you sweat. Most energy drinks are thirsty for these, not full of them. So if you’re doing a marathon or a hot yoga class, plain water or a sports drink might be better.

Here’s a quirky comparison: Energy drinks are like a sports car with no tires. They give you speed (energy) but no grip (electrolytes). Sports drinks are the sensible SUV—boring but reliable. Pick your ride wisely.
One study even found that drinking a sugar-free energy drink before exercise increased urine output by 12%. But that’s from the volume of liquid, not the caffeine. You’d get the same effect from drinking 12 ounces of tea. So blame the water, not the ginseng.
The Real-World Test: You vs. Your Can
Try this: Down an energy drink, then hit the gym. Notice anything? You’ll probably feel more alert, maybe a bit jittery. But you won’t suddenly turn into a desert. Unless you chug it on an empty stomach—then you might get the poo-zles (digestive chaos). But dehydration? Unlikely.
Research from the University of Birmingham had athletes drink a caffeinated energy drink before a 45-minute run. Their urine color (yes, scientists measure that) showed no dehydration. The only thing “dried out” was their opponents’ egos.
So why does the myth persist? Because your grandpa once drank coffee, ran a mile, and peed his pants. He blamed the coffee, but it was probably just old age. Myths stick when they sound plausible, even if science says “meh.”
