Multipliers are applied to each ingredient's dose score when a product is graded. How multipliers are assigned.

How much Vitamin C 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 20 mg per dayLow dose
2. Zone 220 to 60 mg per dayGeneral maintenance dose
3. Zone 360 to 100 mg per dayFor deficiency or elevated need
4. Zone 3100 to 160 mg per dayFor deficiency or elevated need
5. Zone 4160 to 2000 mg per dayTherapeutic 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.
