Spirulina (dietary supplement)

Spirulina is the dried biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are Arthrospira platensis, A. fusiformis, and A. maxima. Recent research has further moved all these species to Limnospira. L. fusiformis is also found to be insufficiently different from L. maxima to be its own species.

Cultivated worldwide, "spirulina" is used as a dietary supplement or whole food. It is also used as a feed supplement in the aquaculture, aquarium, and poultry industries.
