Most health authorities, like the FDA and EFSA, say 400 mg of caffeine per day is safe for most adults. That’s about five 8.4 oz Red Bulls. But that’s a math equation, not a life goal.
Just because you can doesn’t mean you should. That limit ignores your personal sensitivity, your sleep schedule, and the fact that you probably also had a Diet Coke and a piece of chocolate today. Caffeine adds up!
Also, Red Bull contains taurine, B vitamins, and that mysterious “proprietary blend.” Mostly, it’s a legal cocktail of hype and hope. Don’t put your entire energy strategy on one tiny can.
