        HOW THIS COUNTS

        • Caffeine — daily limit 5.7 mg/kg (max 400) for adults, 2.5 mg/kg under 18, 200 with heart issues/pregnancy. Single dose 3 mg/kg (max 200) per 2 h.
        • Body level — absorption ~45 min, half-life from your profile (5 h). Blood mg/L = body mg ÷ (0.7 × kg).
        • Taurine — flagged above 3000 mg/day.
        • Vitamin B6 — EU upper limit 12 mg/day. Red Bull has ~5 mg per 250 ml, so 3 cans already crosses it.
        • Synephrine, yohimbine, alcohol — interaction flags, not dose limits.
        • Pattern — days over limit and daily use across 7 days.
