10 Proven Health Benefits of Spirulina

Spirulina Benefits and Properties


Everyone talks about it, but what are the properties of Spirulina? Let’s see what the scientific community says about this miraculous alga!


Spirulina is a seaweed that takes its name from its unique spiral shape. It is a blue-green alga with powerful properties that have been known since ancient times. Although it has returned to the spotlight in recent times, with the increase in awareness of natural foods and their importance for health, Spirulina was in fact used by the Aztecs for its positive impact on energy and strength and immunity.


Technically, Spirulina is called Arthrospira, and is divided into Arthrospira platensis and Arthrospira maxima, depending on the area of origin. Spirulina only grows in tropical and subtropical lakes characterised by warm water and an alkaline pH, rich in carbonates and bicarbonates. Arthrospira maxima is native to Central America, in particular Lake Texcoco, while Arthrospira platensis comes from Asia and Africa, such as Lake Chad and Lake Chenghai in Yunnan.


Spirulina algae belongs to the Cyanophiaceae family and grows only in very alkaline pristine waters, with high concentrations of mineral salts and with constant temperatures between 30 and 40 degrees. Spirulina has been used for millennia in all areas where it grows, because it is rich in iron, proteins and vitamins, as well as mineral salts and antioxidants. The first news of the existence of this miraculous alga have come to us Europeans since the first expedition of the conqueror Hernán Cortés.


Spirulina: unique nutritional properties


The properties of Spirulina have made it a natural food particularly studied in recent decades. At the United Nations World Food Conference in 1974, spirulina was called “the best food of the future”. Both NASA and ESA (European Space Agency) are evaluating their use in food for future space missions. All this because Spirulina is a complete food with very high nutritional yield.
The green algae, in fact, contains:


  • Up to 77% protein
  • All the essential amino acids for our body
  • Unsaturated fatty acids
  • Chlorophyll and natural antioxidants
  • Vitamins A, B, C, D, E
  • Mineral salts such as potassium, calcium, iron, copper, chromium, magnesium, manganese, phosphorus, sodium, selenium and zinc
