How much Iodine 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 38 µg per dayLow dose
2. Zone 238 to 113 µg per dayGeneral maintenance dose
3. Zone 3113 to 188 µg per dayFor deficiency or elevated need
4. Zone 5188 to 300 µg per dayPractitioner-grade dose
5. Zone 5300 to 600 µg 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.
