How much Copper 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 0 mg per dayLow dose
  2. Zone 20 to 1 mg per dayGeneral maintenance dose
  3. Zone 31 to 2 mg per dayFor deficiency or elevated need
  4. Zone 31 to 1 mg per dayFor deficiency or elevated need
  5. Zone 32 to 5 mg per dayFor deficiency or elevated need

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.
