Spirulina is a blue green micro alga that is especially rich in nutritives.  The speed at which these micro algae convert sun light is the highest known in the plant world which is why Spirulina is also often called "sun food".

Spirulina has been known for thousands of years in many parts of the world. The Aztecs in Mexico and the Mayas in Central America already valued Spirulina as a remarkable addition to their daily diet. The World Health Conference in the United Nations has described Spirulina as the "food of tomorrow". That is not really strange when it is remembered that a gram of Spirulina has as much nutrition as a kilogramme of ordinary vegetables.

Spirulina consists of freely moving spiral threads with a diameter in the region of 0.1 mm that live in strongly alkaline salty water in a temperature of 30 to 35 degrees Celsius. Strictly speaking it is neither a fresh water nor a salt water alga. The many valuable components are formed through natural photosynthesis under the hot sun of the sub-tropical climates of Africa, Asia and Hawaii. Especially the Spirulina from Hawaii (Spirulina Pacifica) is exceptionally valuable.  It is grown in special flat growing basins on a lava plain on the sunny coast of the Pacific.  It is fed with fresh sweet spring water and with sea water taken from a depth of 600 metres, rich in minerals and the biological food dissolved into it. Spirulina from Hawaii has as speciality an extremely fine cell membrane made up of mucopolysacharrides (a sugar complex) and which dissolves immediately on coming into contact with saliva, thus making the more than 100 nutritive elements available at very short notice.

Scientists in many countries have confirmed that there is no other plant which has such a high nutritive value. Spirulina is rich in protein (60 to 71%), vitamins and minerals. Its protein is made up of 18 amino acids, including all those necessary to the human body. Spirulina contains an excellent combination of vitamins and minerals: beta-carotine, vitamins A, B1, B2, B6 and B12, inisitol, folic acid, vitamin E and H and in addition contains phosphor, calcium, magnesium, zinc, potassium, iron, cystein, phycocyamine and carbohydrates as well as gamma-linolic acid and trace elements. Its chlorophyl content is also important; chlorophyl is by far the most important nutritive and the only substance that can pass on stored solar energy to the human body via the digestive process.

Spirulina is an important nutritive supplement for everybody. Spirulina is also recommended as a useful part of the diet in cleansing and slimming diets, partly because of its slight hunger stilling effect.
