Caffeine Safe Limit Calculator
Calculate your absolute safe maximum daily caffeine limit based on your body weight and sensitivity.
Pregnant women and individuals with heart conditions should consult a doctor regarding caffeine intake.
How This is Calculated
Safe daily caffeine limit = body weight (kg) × 6 mg/kg (FDA general adult maximum: 400 mg/day). Sensitivity adjustments: High sensitivity reduces to ~3 mg/kg; low sensitivity allows up to ~8 mg/kg. One cup of brewed coffee ≈ 95 mg caffeine. The EFSA recommends ≤400 mg/day for healthy adults.
