This freshwater algae, also known as Arthrospira platensis, is actually a type of cyanobacterium (also called blue-green algae). It is characterised above all by its extraordinarily high nutrient density and rich phycocyanin content, a plant pigment which gives the blue-green algae its naturally blue undertone. We offer spirulina from a variety of different cultivation methods. Each sourced from the world's leading producers, every individual technique brings its own unique set of advantages to the final product.
