What is spirulina?
Spirulina is a blue-green microalga belonging to the cyanobacteria, one of the oldest life forms on Earth. This microorganism grows naturally in alkaline lakes with a high pH, where it develops its rich nutritional profile. It is packed with vitamins, minerals and other important substances.
But what makes it a true superfood? It is one of the richest sources of plant-based protein, with all the essential amino acids your body needs. It is also a natural source of beta-carotene, vitamin B12, iron and the omega-6 fatty acid gamma-linolenic acid (GLA). This unique nutritional composition has made spirulina a popular food supplement worldwide. (source)
The history of spirulina
Spirulina's popularity today is no coincidence. Throughout the centuries, various cultures have embraced this alga as a valuable source of nutrition. The Aztecs in Mexico, for example, used spirulina. They harvested the alga from Lake Texcoco and made it into nutritious cakes called ‘tecuitlatl’. These were considered an important source of nutrition and energy.
As well as in Central America, spirulina was used in China more than 1600 years ago. Here, a related species of algae, Nostoc commune, was traditionally consumed for its nutritional value. This shows that blue-green algae have a long history of consumption around the world. (source)
What makes spirulina special?
Spirulina stands out from other food supplements thanks to its exceptional nutritional value. It consists of around 60-70% protein, making it one of the best sources of plant-based protein. It also contains:
- Important antioxidants, such as beta-carotene and phycocyanin
- B vitamins and minerals, such as iron, calcium and magnesium
- Essential amino acids, making it a complete protein source
Another unique feature of spirulina is its high bioavailability, which means that the nutrients in this alga are easily absorbed by our bodies. (source)
How spirulina works
Spirulina attracts considerable interest because of its broad nutritional profile. Studies show that substances such as phycocyanin and beta-carotene play an important role in this alga's powerful properties. Research is exploring the extent to which these bioactive substances may support the body in dealing with oxidative stress.
Spirulina is also rich in protein and essential amino acids, making it a valuable addition to vegetarian and vegan diets. The presence of B vitamins and minerals such as iron contributes to the nutritional value of spirulina as a supplement.
Spirulina is also a rare plant-based source of gamma-linolenic acid (GLA), an omega-6 fatty acid that the body produces only in small amounts. GLA plays a role in various bodily processes and is being studied for its contribution to a balanced fatty acid profile. This balance is important, as a good ratio of omega-3 to omega-6 fatty acids may influence our overall health. (source).
Although the research is promising, further scientific evidence is still needed to substantiate these potential benefits.
