Spirulina is a nutrient-dense blue-green microalgae widely recognized for its exceptionally high protein content, typically around 55–70% of its dry weight. It provides all essential amino acids, along with naturally occurring vitamins, minerals, antioxidants, and beneficial pigments.
Its signature blue pigment, phycocyanin, is a powerful antioxidant and one of Spirulina’s most distinctive bioactive compounds. Spirulina is also a source of iron, beta-carotene, and other micronutrients that complement its rich nutritional profile.
With high protein density, efficient cultivation, and relatively low resource requirements, Spirulina offers a sustainable alternative to many conventional protein sources. This combination of protein, nutrition, antioxidants, and sustainability has earned Spirulina its reputation as “The King of Protein.”
