How much Iron 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 4 mg per dayLow dose
2. Zone 24 to 11 mg per dayGeneral maintenance dose
3. Zone 311 to 18 mg per dayFor deficiency or elevated need
4. Zone 418 to 28 mg per dayTherapeutic dose
5. Zone 428 to 40 mg per dayTherapeutic 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.
