Animal study: spirulina is a virus inhibitor
In vitro study
Viruses can glue cells together and make the form aggregates or plaques. The bigger the plaques, the more viruses there are present. The figure below shows that spirulina reduced the size of the plaques.
The doses that the researchers used varied. If the mice had been human, they would have received 80-400 milligrams of extract daily. Based on what the Taiwanese write about the extract, that comes down to 400-2000 milligrams of dried spirulina.
The higher the doses of spirulina extract, the greater the survival rate of the mice.
"A cold water extract of spirulina [...] significantly inhibited virus infection and replication in a broad range of influenza viruses", write the researchers. "Survival was also improved in influenza-infected mice treated with Spirulina extract."
"With a long history of food use, high tolerated dose, and broad spectrum of anti-influenza activities, spirulina extract may serve not only as a viable therapy for the treatment of influenza, but also as a potential prophylaxis for the prevention of disease."
