Spirulina: Origin, Nutrient Profile, and Everyday Use

What's behind the blue-green microalgae?

Spirulina is one of the best-known microalgae and has been valued for many years as part of a conscious diet. Due to its natural nutrient content, it is often referred to as a "superfood". Spirulina is actually a dried biomass of cyanobacteria that grows in warm, alkaline waters.

Today, Spirulina is primarily cultivated in controlled aquacultures to ensure consistent quality and purity. Gentle drying largely preserves its natural nutrient profile.

Origin and cultivation of Spirulina

Spirulina naturally occurs in warm regions with high pH values, such as parts of Africa, Asia, or Central America. Indigenous cultures used Spirulina as a food source centuries ago.

For modern food supplements, Spirulina is usually:

• cultivated in freshwater tanks

• harvested under controlled conditions

• then dried and processed
