So what exactly is so special about this product? Let us take a close look at spirulina superfood.

About Spirulina

Spirulina is a blue-green alga which comes under the cyanobacteria category. 

Each individual algae has a length of about 300-500 microns and embedded within the algae is unfathomable strength of life's vital forces.

This unicellular organism got its name coined from the Latin word "Spira" which means 'spiral' or 'helix', due to its appearance when looked under a microscope.

Scientifically, spirulina is known as Arthrospira platensis, one of the oldest living organisms present on the earth.

For most people, the entire idea of consuming blue-green algae won't be a delectable choice. Surprisingly, this tiny microorganism powers the entire food chain.

Historically spirulina has been the fundamental choice of nutrition for the great civilizations which existed around the globe. Cultures such as Mayans, Aztecs and the Toltecs are known to use this extensively in their diet.

The soft cell wall of this algae makes it easy to digest, helping the body to access all the nutrients with utter ease.

Where does spirulina come from?

Spirulina in its natural form can be found in many freshwater rivers, lakes and ponds that are rich in minerals. Many naturally occurring sites have been discovered in water bodies near volcanoes.

Environments with moderate temperature and very high levels of sunlight are best for growth. Extensive growth has been found at salt lakes of South and Central America and Africa.

The largest concentration of spirulina has been found around Lake Chad in Central Africa, along the Great Rift Valley in East Africa and at Lake Texcoco in Mexico.

Ever since its rediscovery in the 1960s, spirulina has been extensively tested by researchers all over the world. It is found to be the most well balanced and potent source of nutrition available on the planet.

The alga gained immense popularity as a superfood in 1963. A French botanist Jean Leonard during his expedition in Africa described a blue-green cake sold in the food market Fort Lamy, Chad. Popularly known in the local dialect as Dihe, consumed by the Kanembu tribe living close by.

Why is spirulina a superfood?
