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

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


The extremely nutritional and ecofriendly spirulina (arthrospira platensis) has hypolipidemic, hypoglycemic, and antihypertensive properties. Spirulina includes functional compounds, such as phenolics, phycocyanins, and polysaccharides, with antioxidant, anti-inflammatory, and immunostimulating impacts. Studies conducted on spirulina recommend that it is safe in healthy topics, however attitude to consuming most likely impacts the acceptability of spirulina including foods. Although the antioxidant result of spirulina is validated by the intervention research studies, the concerted modulation of antioxidant and inflammatory actions, recommended by in vitro and animal research studies, requires more confirmation in human beings. Spirulina supplements seem to affect more effectively the innate resistance, promoting the activity of natural killer cells. The effects on cytokines and on lymphocytes’ expansion depend on age, gender, and body weight differences. In this context, aging and weight problems are both related to persistent low grade swelling, immune disability, and intestinal tract dysbiosis. Microbial-modulating activities have actually been reported in vitro, recommending that the association of spirulina and probiotics might represent a new technique to enhance the growth of beneficial intestinal microbiota. Although spirulina may represent a functional food with potential advantageous impacts on human health, the human interventions used only supplements. For that reason, the effect of food including spirulina needs to be examined in the future. (2 ).


Spirulina, likewise understood asarthrospira platensis, is a blue microalga that grows in alkaline fresh water and at high temperatures. First by fao, in 2008 and after that by the un, in 2011, the very food of the future for sustainability, completeness of nutrients and for the many advantageous 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.
