A Short History

Historians believe the Aztecs were the first people in history to use Spirulina. They dried the algae into cakes which were thought to have been used as their primary source of protein. In 1940, explorer Pierre Dangeard published a report on this “nutritious algae” that was being eaten by people living around Lake Chad in Central Africa. About twenty-five years later, botanist Jean Leonard noticed the sale of green cakes in the markets there. He observed about 70% of the food eaten in this area was accompanied by a sauce made from the dried Spirulina cakes.

In 1967, Spirulina was established as a “wonderful future food source” in the International Association of Applied Microbiology (Sasson, 1997).

Where Is Spirulina Found?

This free-floating cyanobacteria lives in colonies and occurs naturally in tropical and subtropical lakes. It can also be found in soil, marshes, freshwater, brackish water, seawater, and thermal springs where the water’s pH is high. Spirulina is native to Africa, Asia, and South America.

Spirulina can also be cultivated in open-channel raceway ponds or man-made tanks. Tanks help reduce the alga's exposure to potential contaminants in the water.

Why Are People Eating Microalgae?

Spirulina is one of the world’s most popular supplements because it is a nutrient-dense superfood. This tiny organism is loaded with nutrients and antioxidants. It is also a complete protein, which means it contains all essential amino acids.

Once dried and powderized, Spirulina is added to healthy drinks and smoothies, and can be sprinkled directly on top of salad or incorporated into cooked meals.
