Blue spirulina is a vibrant blue pigment extracted from Arthrospira platensis (blue-green algae), scientifically known as phycocyanin. Unlike regular green spirulina, blue spirulina is the isolated protein-phycocyanin complex that gives the algae its blue hue. This natural colorant has been used for centuries by the Aztecs and African communities as a nutrient-dense food source.
The modern extraction process involves cultivating spirulina in controlled environments, then carefully isolating and purifying the phycocyanin through a water-based extraction method. The result is an intensely blue powder that's 100% natural, vegan, and free from the earthy taste of regular spirulina.
Blue spirulina has gained global popularity not only for its striking color but also for its impressive nutritional profile. It's commonly used in health foods, smoothie bowls, desserts, and even cosmetics as a natural coloring agent and functional ingredient.
