Multipliers are applied to each ingredient's dose score when a product is graded. How multipliers are assigned.
How much Glucosamine should you take?
SuppScore grades doses across evidence zones rather than against a single recommended figure. Scored information, not a recommendation.
- Zone 10 to 375 mg per dayLow dose
- Zone 2375 to 750 mg per dayGeneral maintenance dose
- Zone 3750 to 1350 mg per dayFor deficiency or elevated need
- Zone 41350 to 2620 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.
