                                Historically used as a food source by the Aztecs, spirulina is a type of cyanobacteria known for its high nutritional value. While many assume it is a single organism, the question "Are there different types of spirulina?" has a nuanced answer, particularly when considering taxonomy and commercial products. Understanding these variations is key to choosing the right supplement for your health needs.
