Spirulina is a biomass of cyanobacteria (blue-green algae) that can be taken in by humans and animals. The three types are arthrospira platensis, a. Fusiformis, and a. Maxima.

Cultivated worldwide, arthrospira is used as a dietary supplement or entire food. It is likewise utilized as a feed supplement in the aquaculture, fish tank, and poultry industries.


The highly dietary and ecofriendly spirulina (arthrospira platensis) has hypolipidemic, hypoglycemic, and antihypertensive homes. Spirulina contains practical compounds, such as phenolics, phycocyanins, and polysaccharides, with antioxidant, anti-inflammatory, and immunostimulating effects. Studies performed on spirulina suggest that it is safe in healthy subjects, however attitude to consuming most likely affects the acceptability of spirulina containing foods. Although the antioxidant effect of spirulina is validated by the intervention studies, the concerted modulation of antioxidant and inflammatory actions, suggested by in vitro and animal studies, requires more confirmation in people. Spirulina supplements appear to affect more effectively the inherent resistance, promoting the activity of natural killer cells. The effects on cytokines and on lymphocytes’ expansion depend upon age, gender, and body weight distinctions. In this context, ageing and weight problems are both associated with chronic low grade inflammation, immune disability, and intestinal tract dysbiosis. Microbial-modulating activities have been reported in vitro, suggesting that the association of spirulina and probiotics could represent a brand-new method to improve the development of beneficial intestinal tract microbiota. Although spirulina might represent a practical food with prospective useful results on human health, the human interventions utilized just supplements. Therefore, the impact of food consisting of spirulina needs to be evaluated in the future. (2 ).


Spirulina, also understood asarthrospira platensis, is a blue microalga that grows in alkaline fresh water and at heats. First by fao, in 2008 and then by the un, in 2011, the very food of the future for sustainability, completeness of nutrients and for the many beneficial qualities it possesses.

Food is history, it is culture, it is custom and spirulina, as food, brings with it a history, a culture and a custom that are lost in the mists of time.

It is over three billion years of ages and is one of the earliest foods on the planet.

It initially grew in america and africa, more particularly in lake texcoco in mexico and lake chad in north-central africa.

The very first trustworthy historic documents on making use of this alga come from the testimony of thei conquistadors spaniards, to start with cortés who, following the intrusion and conquest of the aztec people from 1519-1525, reported having actually found a green food, served in the form of a pie, which the aztecs called food of the gods.i dei”.

They extracted this substance from the lakes of the anahuacusata valley in mexico to utilize it in meals or for magical-ritual and medical purposes.

In more current times, spirulina was found by a french botanist, jean léonard who, at the head of a trans-saharan belgian exploration, in 1965 reported seeing edible green cakes prepared and offered by the ladies of the kanembu people in the markets of the villages along the banks of chad.

Later on, in between completion of the 60s and the beginning of the 70s, the institut francais du petrol called a mexican company, sosa-texcoco to request permission to follow and study the lake blooming of spirulina algae.ina.

After a short time, in the late 1970s, the very first large-scale production plant was born right on the coasts of lake texcoco.

Today spirulina is cultivated in numerous nations of the world in specifically created aquaculture and more prevalent in australia, central america, southeast asia and africa.

In europe, the crops spread out generally to france and italy.

This food, amongst the most complete on the planet, is now also offered to astronauts as a dietary supplement throughout area explorations.

In order to keep intact all its organoleptic properties, extremely useful for the body, spirulina must be pure! Produced and dispersed exclusively in the form of fresh pasta – because it is still alive and enzymatically active – to be taken in within a week, or dried under 45 to extend the storage time up to 36 months.mesi).

Spirulina is history however it is also the future. The food of the future. (3 ).


Spirluina are aquatic organisms, usually occupying freshwater alkaline lakes. However, there are marine types also. They are mesophilic, and able to endure over a wide range of temperature levels; some species are even discovered in warm springs. Spriulina is edible germs. Flamingos get their pink color from consuming spirulina that contain phycoythrin. People likewise consume germs. It is known that the aztecs consumed it frequently, and it might be an essential dietary element in tropical areas. It is also utilized in asian cusine. In america, spirulina is offered in natural food stores as a powder or tablet. In russia, it was authorized to treat symptoms of radiation illness after chernobyl, since the carotenoids they include take in radiation. Evidence reveals that it is capable of stopping viral replication. It avoids the infection from permeating a cell wall and infecting the cell. Spirulina also increase the production of cytokines. This advantage originates from the antioxidants present within the organisms. Spirulina are an outstanding source of both protein and iron, and work in the treatment of anemia. They can likewise serve as a food source for intestinal tract plants such as lactobacillus and bifidus. Research study by wang et. Al. (2005) that germs also slows neurological damage in aging animals, and keeps in mind that it can reduce the damage caused by stroke. Research studies likewise show that spirulina can prevent the release of histamines, treating allergic reaction symptoms.

Spriulina has nonmedical usages too. A research study by chen and pan (2005) shows that the germs can get rid of low concentrations of lead from wastewater. Research study by da costa and de franca (2003) shows that spirulina is likewise capable of removing cadmium from its environment. (4 ).

Components of spirulina


The most significant bioactive compounds in spirulina are the phycocyanins, consisting of c-phycocyanin. This is a powerful anti-oxidant and anti-inflammatory molecule with an unexpected cascade of impacts: it has been discovered to safeguard brain and liver cells.

C-phycocyanin has a really similar structure to the human blood protein bilirubin, which is a product of the breakdown of old red cell. Bilirubin happens to be a natural antioxidant: it binds to oxygen totally free radicals to form biliverdin. Elevated bilirubin can signal an underlying health issue, however in many people, bilirubin is protective. Individuals with low levels of bilirubin are most likely to struggle with atherosclerosis and heart problem. C-phycocyanin might help bring back the oxidative balance in individuals with low bilirubin.

Spirulina is rich in phycocyanins, which are comparable in structure to human bilirubin, a natural anti-oxidant.

Other functional compounds

Spirulina boasts a range of bioactive compounds like phenols, flavonoids, and polysaccharides. The phenols and flavonoids contribute to this algae’s anti-oxidant and anti-inflammatory residential or commercial properties; the polysaccharides boost the immune action.

Essential nutrients.
