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.

- Zone 250 to 150 mg per dayGeneral maintenance dose
- Zone 3150 to 200 mg per dayFor deficiency or elevated need
- Zone 5200 to 400 mg per dayPractitioner-grade dose
- 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.
