Spirulina corakiana |
Spirulina is a genus of filamentous cyanobacteria (commonly called blue-green algae), with a coil-like shape. ITIS recognises 13 species.
Spirulina is also the commercial name for the species Arthrospira platensis (previously known as Spirulina platensis), which is cultivated around the world as a food source. It is a very rich source of nutrition. In fact, it was a staple of Aztec cuisine. The genus is also responsible for the flamingo's pink plumage.
It is currently popular as a health food in the U.S. and Europe, often taken as a dietary supplement in the form of powder or tablet.
Vegetarians and vegans should not rely on spirulina (among certain other foods) as a source of vitamin B12. See the B12 article for more information.
