Spirulina is a type of blue-green algae, scientifically classified as cyanobacteria, that has garnered significant attention for its impressive nutritional profile. It’s considered a “superfood” because it’s packed with vitamins, minerals, antioxidants, and protein. Historically, it was consumed by ancient civilizations like the Aztecs, and more recently, it has been used as a dietary supplement for astronauts during space missions. Spirulina thrives in warm, alkaline water and is commercially available in various forms, including powders, tablets, and capsules. Its rich composition includes essential nutrients like B vitamins, iron, and copper, as well as phycocyanin, a pigment with antioxidant and anti-inflammatory properties. While generally considered safe, it’s crucial to obtain spirulina from reputable sources to minimize the risk of contamination.
