How much L-Arginine 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 750 mg per dayLow dose
2. Zone 2750 to 2250 mg per dayGeneral maintenance dose
3. Zone 32250 to 3000 mg per dayFor deficiency or elevated need
4. Zone 53000 to 9000 mg per dayPractitioner-grade dose
5. Zone 59000 to 13500 mg 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.
