How much L-Glutamine should you take?
SuppScore grades doses across evidence zones rather than against a single recommended figure. Scored information, not a recommendation.
- Zone 10 to 1250 mg per dayLow dose
- Zone 21250 to 3750 mg per dayGeneral maintenance dose
- Zone 33750 to 5000 mg per dayFor deficiency or elevated need
- Zone 45000 to 20000 mg per dayTherapeutic dose
- Zone 420000 to 30000 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.
