Most of us aren't doing complex calculations when we crack open a can; we just want the jolt. But the lethal dose of caffeine for an average adult is roughly 10 grams spread out over a short period. A standard 8.4-ounce Red Bull has about 80 milligrams of caffeine. So, do the quick mental math, and you’re looking at roughly 125 cans.
Let that sink in. That’s not a case of Red Bull. That’s a pallet of Red Bull. That’s enough to fill a small bathtub, which, by the way, is not a good place to drink it. You’d have to chug one can every few minutes for hours, and your stomach would probably stage a rebellion long before your heart gave out.
Realistically, you’d be in the bathroom so often that you’d miss your own funeral. I once drank four in one night to study for a final, and I thought my eyeballs were going to vibrate out of my skull. Imagine 125. You’d be a human tuning fork.
But Wait, There’s More Than Just Caffeine
It’s not just the caffeine, though. Red Bull is a cocktail of taurine, B vitamins, and sugar. The sugar is the sneaky villain here. That same 125-can scenario would have you consuming over 3,000 grams of sugar—enough to send you into a diabetic coma before you even got half way through the pile.
Think of it like this: you wouldn’t eat 125 candy bars in one sitting, so don’t try the liquid version. And the taurine? It’s an amino acid found in bull testicles—no, really—but in these doses, your body would just flush it out. Your kidneys would be working overtime, filing expense reports for every sip.

So the real answer is that you’d die of liquidity poisoning. Your blood would turn into a fizzy, sweet syrup, and your heart, which is basically a dumb, loyal pump, would say, “Hey boss, I’m tired,” and just clock out.
