The algae found in the formula have unique cell walls made of complex polysaccharides, which have been shown to stimulate interferon production and exhibit strong anti-tumour activity in a series of studies conducted over the last several decades.

Polysaccharides are relatively complex carbohydrates. They are polymers made up of many monosaccharides joined together by glycosidic bonds. Cell-surface polysaccharides as in microalgae like spirulina play diverse roles in the bacterial "lifestyle". They serve as a barrier between the cell wall and the environment and mediate host-pathogen interactions.

Studies on the consumption of food-grade microalgae have reported enhanced immune function in animals and humans.


  • Dietary spirulina has been shown to exhibit chemopreventive* and antiviral effects in humans. The active component for these effects has been investigated; it appears that several types of polysaccharides exhibit biological activity
  • Calcium spirulan inhibits replication of several enveloped viruses. These include herpes simplex, cytomegalovirus, mumps and measles viruses and influenza A virus
  • Another polysaccharide found in spirulina, immunlina, has been shown to activate monocytes and macrophages, which are central cells of the innate immune system, responsible for defending against diverse pathogens
  • Spirulina polysaccharides are clinically observed to provide immune system modulation and reduction of blood sugar levels to normal
  • Scientists also found that spirulina's polysaccharide acts similarly to Phycocyanin, a highly potent agent that activates the immune system. It improves the immune system's ability to detect and destroy foreign microbes or eliminate toxins. It also enhances T-cells and improves Thymus gland function. Also observed were increased antibody levels and normalisation of other cellular functions
