A type of blue-green algae, spirulina is a microscopic aquatic plant species. The two most common species consumed by humans are Spirulina maxima and Spirulina platensis. Spirulina is rich source of nutrients. It is high in protein, and it also contains Carotenoids, vitamins, minerals, and Essential Fatty Acids (1). Most supplemental uses of spirulina and other blue-green algae are based on anecdotal rather than scientific evidence. A number of test tube and animal studies have shown that large amounts of spirulina possess antiviral (2), antiAllergy (3,4), immune-enhancing (5) effects.
Spirulina is not an essential nutrient. However, it does contain a number of important nutrients, and can be used as a source of protein as well as Carotenoids. In general, large amounts of blue-green algae are necessary to provide significant amounts of nutrients.
Spirulina is available as a powder, flakes, capsules, or tablets.
