Spirulina is a powder produced from a water-based organism that appears blue in color, even though it uses sunlight to produce energy like green plants do. Spirulina is a popular “super food” taken in capsule form or added directly to smoothies, yogurt, soups and other foods and beverages. Spirulina is a rich source of calcium iron, protein, essential fatty acids, B vitamins, trace minerals, carotenoids and other antioxidants.
Spirulina powder is obtained from a free-floating aquatic organism commonly referred to as a blue-green algae, although it’s actually a type of cyanobacteria. This simply means that it manufactures energy using photosynthesis just like plants, despite being blue in color. As a rich source of fatty acids, minerals, vitamins and various oxidants, spirulina powder is added directly to foods or is encapsulated as a dietary supplement.
