What is Spirulina?

Home / What is Spirulina?

Spirulina (Athrospira platensis) is a microscopic blue-green algae, or cyanobacteria. The important thing about cyanobacteria is that they photosynthesize. That is, just like trees, they capture the sun’s light energy into their bodies and use it to make carbohydrates from CO2. In so doing, they release oxygen.In primordial epochs, when life was just beginning, it was the actions of Spirulina, and other cyanobacteria, that put oxygen in the atmosphere. This allowed life on earth to explode, thrive and diversify into all its wondrous forms including you and me.

Spirulina – A Blue Green Algae With Benefits

Spirulina was here at the beginning of time and is one of the earth’s older species. It floated around in the primordial seas over 3.6 billion years ago when life was just getting started. In fact, Spirulina and its cousins are among the original species which gave rise to all other life forms.

The take home message here, is that Spirulina is a survivor. Perhaps, as we go forward to an uncertain future, Spirulina will help us survive too.

Spirulina Can Take Different Forms

Just like the morphological variation that can be observed in the same species of animals or plants – think of the different races of humankind – Spirulina has different forms depending on where they originate and the conditions under which they are grown. The trichomes (multi-celled filaments) can be straight or tightly spiralled and anywhere in between. What they all have in common, is their chemical make-up and, by extension, their nutrient profile.

The Natural Habitat of Spirulina

In nature, Spirulina grows in mineral-rich lakes that are often found near volcanoes or places with thermal activity.  The largest Spirulina lakes include Lake Texcoco in Mexico, lakes along the Great Rift Valley in East-Africa; and Lake Chad in Central Africa.

Spirulina Has Been Harvested For Centuries

Civilizations have eaten Spirulina for centuries, including the Mayans and Incas. Spirulina is still harvested for food by the Kanembu people living around Lake Chad. Women collect the Spirulina and filter out the water in the sand. The dried ‘flatcakes’ – called dihé – are sold in local markets.

Spirulina is Highly Nutritious

Spirulina is so nutritious and easy to cultivate, that the United Nation’s Food and Agricultural Organization (FAO) claim that Spirulina is “the most ideal food for mankind” and have called upon nations to look to Spirulina to fulfill their food security needs. Further, because Spirulina is so nutrient-rich whilst being resource use efficient, the United States Department of Agriculture declared that “Spirulina is the food for the future”.  Further, NASA has investigated the cultivation of Spirulina for space travel.

It comes as no surprise therefore, that Spirulina is recognized as the most nutrient dense food on the planet. Find out more …

Not only is Spirulina highly nutritious, it also has a whole suite of health and medicinal benefits.
