Red Bull is a sugary drink made from a mix of water, sugar, and industrial flavorings. You're not getting any real nutrition from this stuff, just a crash from the caffeine and a stomachache from the sugar. It's a chemical cocktail, not a food.
Why trash
Synthetic caffeine, sugar, and taurine in a tiny overpriced can.
Try instead
Coconut water, water with lemon, or unsweetened almond milk.
