Spirulina (Artrospira platensis)

Spirulina is a microscopic algae that is almost as old as life on Earth. It grows in fresh water rich in mineral salts. It exists naturally in certain areas and is now cultivated in ponds. In addition to being exceptionally rich in beta carotene and vitamins, that can considerably improve the absorption of iron, Spirulina contains phycocyanine, a natural blue pigment and chlorophyll.
