Famed for its vibrant deep green hue, spirulina is often called a “superfood.” But, what’s so special about this microscopic, blue-green algae?

Spirulina’s usage can be traced back to ancient civilizations, as early as the 16th century Aztecs. Indigenous communities harvested and sun-dried spirulina, forming cakes that served as a valuable source of nutrition. Similarly, the Kanembu people in Chad have been using spirulina for centuries, harvesting it from Lake Chad and shaping it into small cakes called “dihe.”

Spirulina’s modern popularity really burst onto the scene in the 20th century when NASA decided to explore it as a potential food source for astronauts due to its exceptional nutritional content.

Today, spirulina’s use as a dietary supplement and health food has grown exponentially because of its remarkable potential health benefits.
