FAQ
Does sugar-free Red Bull still give you energy?
Yes, its primary energy boost comes from caffeine (about 80mg per 250ml can) and B-vitamins, not sugar.
Is it safe to drink every day?
Moderate consumption (1-2 cans) is generally considered safe for healthy adults, but daily use can lead to caffeine dependence and may affect sleep or heart health.
What is taurine, and why is it in there?
Taurine is an amino acid found naturally in the body. It's included for its potential role in supporting neurological development and regulating minerals, though its exact synergistic effect with caffeine in energy drinks is still studied.
