Dosage information
Spirulina is usually dosed in the range of 2 to 10 grams daily in whole powder or capsule form. Extracts are sometimes used, but they are less thoroughly studied and do not contain the full array of compounds found in dried spirulina.
Higher doses of spirulina, in the range of 4 to 10 grams daily, appear to be most effective for improving lipid profiles and possibly for reducing fatigue during endurance exercise.[1][2]
A lower dose of 2 grams daily may help reduce symptoms of allergic rhinitis.[3]
