It may also protect against other disease causing microbes and cancer. Because it is a safe natural food, it has created a sensation among animal scientists. They are scrambling to replace ineffective antibiotics with probiotics like spirulina that strengthen immune systems and prevent disease. In 1979, Russian scientists published initial research on the immune stimulating effects on rabbits from lipopolysaccharides in spirulina.7 These discoveries are significant for human health. Overused antibiotics have created highly resistant bacteria.
Most antibiotics are no longer effective.
Now scientists want to identify probiotics that strengthen the immune system to prevent disease and cancer. Based on this animal research, as little as 3 grams per day of spirulina may be effective for humans. It seems to turbocharge the immune system to seek out and destroy disease causing microorganisms and cancer cells. Its dark green color comes from the combination of the phytonutrients carotene, chlorophyll and phycocyanin. It is also a source of polysaccharides and sulfoglycolipids.
