Spirulina (dietary supplement)
Spirulina is the dried biomass of cyanobacteria 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. The genus Arthrospira was formerly classified in the genus Spirulina, hence the name.
