Spirulina, a simple, one-celled organism, is also commonly called an all-natural blue-green’ algae owing to its color and its sources. It grows in the surface of freshwater lakes and ponds with a high pH (alkaline) and after being harvested, you can purchase Spirulina in tablet, powder and liquid forms.

This deep green aquatic plant is recognized as one of the oldest life forms on earth. In fact, the microalgae is partly responsible for producing the planet’s atmospheric oxygen that billions of years ago allowed the earth’s originating life forms to develop. The Aztecs consumed Spirulina in 16th century Mexico for its abundant source of protein. The people of the Kanem empire used it as a food source over a thousand years-ago in ancient Chad. Today, it is renowned as one of the world’s most nutritionally-complete superfoods, thanks to its exceptional nutrient-dense composition and offering health benefits to virtually every organ and bodily function.

Spirulina gained popularity when NASA used-it as a dietary-supplement for astronauts in space. Spirulina did not come into commercial production up until the 1970s when one French company began the first large scale Spirulina production plant.
