The available review was specific to HIV-related nutrition
No immune-protection claim for SPRU

Spirulina has been studied in nutritional research, but those studies do not establish that SPRU prevents or treats infections or strengthens immunity.

A 2013 Cochrane review examined nutritional interventions in people living with HIV. It included trials of spirulina among other interventions, but it was not a study of SPRU or a general test of infection prevention in healthy people. The review cannot support an immune-protection claim for our product. Read the review on PubMed.

SPRU is a food, not medicine, and is not a substitute for vaccination, prescribed treatment or medical care.
