Energy drinks are where people most often blow past a safe caffeine limit without noticing, because the number on the can ranges from modest to enormous.
Caffeine by the can
- Red Bull (8.4 oz): about 80 mg
- Monster (16 oz): about 160 mg. White Monster: about 160 mg
- Celsius (12 oz): about 200 mg
- Alani Nu (12 oz): about 200 mg
- Bang (16 oz): about 300 mg. Reign (16 oz): about 300 mg
- 5-Hour Energy (1.9 oz shot): about 200 mg
Why it's easy to overdo
A single Celsius or Alani is already half the 400 mg daily limit for adults. Drink two of them, plus a morning coffee, and you're over, often without feeling like you drank that much. The large serving size hides the dose.
Caffy has these energy drinks built in with up-to-date caffeine amounts, so one tap logs the real number and warns you before two cans push you past your daily limit.
