How much Caffeine Anhydrous should you take?

SuppScore grades doses across evidence zones rather than against a single recommended figure. Scored information, not a recommendation.

  1. Zone 10 to 50 mg per dayLow dose
  2. Zone 250 to 150 mg per dayGeneral maintenance dose
  3. Zone 3150 to 200 mg per dayFor deficiency or elevated need
  4. Zone 5200 to 400 mg per dayPractitioner-grade dose
  5. Zone 5400 to 600 mg per dayPractitioner-grade dose

Zones describe what the evidence supports at a dose. They are not advice on what to take, and they do not replace a conversation with a doctor or pharmacist.
