For centuries, civilizations have harvested spirulina, but its true biological identity is often misunderstood. Although commonly referred to as a blue-green algae, the scientific answer to 'what is spirulina classified as?' points to a different, more ancient, group of organisms: cyanobacteria.

According to scientific research, spirulina is not technically an algae but a type of cyanobacteria. Spirulina is also known by several common and scientific names, which often leads to confusion about its classification and properties.

While commonly sold and marketed as a 'blue-green algae,' spirulina is technically a type of cyanobacterium and was reclassified into the genus *Arthrospira* in the mid-20th century. This taxonomic reclassification, which also includes the newer genus *Limnospira* for modern cultivated strains, means that another name for spirulina is, scientifically speaking, *Arthrospira*. However, in commercial and popular contexts, the original, familiar name has persisted.

Multiple scientific studies report that certain microalgae, particularly Spirulina, can be composed of up to 70% protein by dry weight. This incredible protein density has sparked growing interest in algae as a sustainable protein source and has many people asking which algae has the highest protein.

Did you know that NASA included spirulina in astronauts' diets for its high nutrient density? With its long history and impressive profile, it's a popular topic for those exploring a nutritional diet, leading many to ask: **what is the other name for spirulina?**
