How much Selenium 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 14 µg per dayLow dose
  2. Zone 214 to 41 µg per dayGeneral maintenance dose
  3. Zone 341 to 69 µg per dayFor deficiency or elevated need
  4. Zone 369 to 110 µg per dayFor deficiency or elevated need
  5. Zone 5110 to 300 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.
