When I tried drinking Red Bull, I was like, “Wow! I’m smart again! Forget wings... this gives me brain cells!” Then, I read several articles saying the who Taurine fad was a load of nonsense; that Red Bull merely was a caffeine-based stimulant. Since coffee or soda makes me feel LESS intelligent, that explanation didn’t wash with me. But I noticed Red Bull also contains lots of vitamin B-12, so I tried taking B-12 supplements.
The liquid-form B-12 supplements have a similar effect as Red Bull. I’m guessing the solid-form ones I’ve had just aren’t digested as well. But I’m fairly certain that B-12 is a key ingredient to why Red Bull has such an effect on me.
