How much Kelp Extract 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 150 mg per dayLow dose
  2. Zone 2150 to 400 mg per dayGeneral maintenance dose
  3. Zone 3400 to 800 mg per dayFor deficiency or elevated need
  4. Zone 4800 to 1500 mg per dayTherapeutic dose
  5. Zone 51500 to 3000 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.
