Spirulina is an ancient single-celled prokaryotic microorganism. It has lived on the earth for about 3.5 billion years, and the age of the earth is only 4.6 billion years. Since its discovery, many legends have been accompanied by this ancient algae.

The protein content of Spirulina platensis ranges from 58.5% to 834%, and the proportion of amino acids is appropriate. Among them, 8 kinds of essential amino acids are close to or exceed the proportion standard recommended by the Food and Agriculture Organization of the United Nations (FAO). The protein digestibility and bioavailability of Spirulina platensis are 75.0% and 68.0% respectively. Spirulina is considered to be the highest protein content and the best quality food known by human beings.

Fat

Spirulina is a kind of low-fat food with a fat content of 6%-9%, and its fatty acids are mainly unsaturated fatty acids. The content of Y-2 linolenic acid is 4.9%~5.7%. Especially, the content of essential fatty acid is high. The content of Y-2 linolenic acid with various health functions is as high as 8.75~11.97 g/kg.


Vitamin


Spirulina cells divide actively, grow rapidly and metabolize vigorously. Therefore, the vitamins directly related to growth and development are also abundant, especially the contents of beta-carotene, vitamin E and vitamin B12 are higher, of which beta-carotene is the top of all foods, 10 times higher than carrot. The content of vitamin B12 is 3.5 times that of animal liver.

Mineral


Spirulina is rich in minerals, especially selenium compared with common terrestrial food. These minerals are combined with organic substances, easy to be absorbed and utilized by the human body, and can effectively regulate the balance of the body and the activity of enzymes.


Bioactive substances

Spirulina also contains Spirulina polysaccharides, phycocyanin and other bioactive substances. Phycocyanin is not only a good natural pigment, but also can improve the immunity of organisms. It has obvious effect on inhibiting the growth of cancer cells.
