How much Friendly bacteria 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 3 billion CFU per dayLow dose
  2. Zone 23 to 5 billion CFU per dayGeneral maintenance dose
  3. Zone 35 to 15 billion CFU per dayFor deficiency or elevated need
  4. Zone 415 to 30 billion CFU per dayTherapeutic dose
  5. Zone 530 to 50 billion CFU 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.
