Red Bull contains 32mg of caffeine per 100ml (80mg per 250ml can), which triggers the EU/UK mandatory 'high caffeine content' warning on the label. The caffeine is equivalent to roughly one small espresso per can. Red Bull uses taurine (0.4%), an amino acid originally sourced from bull bile — now synthetically produced — which is claimed to have a synergistic effect with caffeine, though evidence for enhanced cognitive performance beyond caffeine alone is limited.
