Spirulina refers to a biomass of cyanobacteria (Arthrospira platensis and Arthrospira maxima) that can be consumed by humans and other animals. These filamentous, photosynthetic bacteria grow in fresh and saltwater and are distinguished by their rich nutritional profile. Historically, spirulina was utilized by ancient civilizations, including the Aztecs in Mexico, who harvested it from Lake Texcoco. Its modern appeal as a dietary supplement stems from its high content of protein, vitamins, minerals, antioxidants, and phycocyanobilin, a blue pigment and chromophore which contributes to its unique color.
Commercially, spirulina is cultivated in large outdoor ponds and subsequently harvested and processed into various forms, including powder, flakes, and tablets. It is often marketed as a 'superfood' due to its comprehensive nutrient density. The interest in spirulina extends beyond its nutritional aspects, with research exploring its potential health-promoting properties related to its antioxidant, anti-inflammatory, and immunomodulatory effects. Understanding spirulina involves examining its biochemical composition and the scientific studies that investigate its physiological impacts. (Source: NIH ODS, PubChem)
