Rating (out of 5): 2

Spirulina, a blue-green algae, has been studied for its potential antiviral properties, particularly in relation to respiratory viruses such as those causing the common cold. Laboratory (in vitro) studies have demonstrated that extracts of spirulina can inhibit the replication of several viruses, including influenza and herpes simplex virus, by interfering with viral entry and replication. Some animal studies also suggest that spirulina supplementation can enhance immune responses, such as increasing the activity of natural killer cells and promoting the production of cytokines, which may help the body combat viral infections.

However, human clinical evidence specifically supporting the use of spirulina to prevent or treat the common cold is limited. Most available studies focus on its general immune-modulating effects or its antiviral properties against viruses other than those typically responsible for colds (such as rhinoviruses). While a few small trials have suggested that spirulina may reduce the incidence or severity of viral infections, these studies are preliminary, often of low quality, and usually not directly focused on common cold viruses.

In summary, while laboratory and animal studies provide a scientific rationale for the antiviral and immune-supportive effects of spirulina, robust clinical evidence in humans for its use against the common cold is lacking. More well-designed clinical trials are needed to confirm any benefits for this specific condition.
