Spirulina as a Nutritional Supplement
While interest in some other micro organisms has faded owing to their high acid content or indigestibility, Spirulina has been singled out as being an easy solution to producing a high quality nutritional supplement.
The blue – green algae, Spirulina in particular, are rich in ribosomes, which are cellular organelles that exist within the cell and are the site for protein manufacture. This means that Spirulina has a photosynthetic conversion rate of 8 to 10 percent, compared to only 3 percent in such land-growing plants as soybeans and contains a remarkable 60 – 70% protein.
These proteins are complete proteins – meaning they contain all eight amino acids in the correct ratios. Most plant foods are not complete proteins because they lack one or more amino acids.
Spirulina is being developed as the "food of the future" because of its amazing ability to synthesize high-quality concentrated food more efficiently than any other algae. In addition, the lack of the hard cell wall means that the protein from Spirulina can be more easily digested.
As well as the very high protein content, Spirulina is also packed full of vitamins, minerals, essential fatty acids and trace elements. In particular, Spirulina is one of the few plant sources of vitamin B12, usually found only in animal tissues. A teaspoon of spirulina supplies 2 1/2 times the Recommended Daily Allowance of vitamin B12 and contains over twice the amount of this vitamin found in an equivalent serving of liver. B12 is by far the most difficult vitamin to find in a non meat diet.
Typical Nutritional Analysis
Protein |
60 – 70% complete protein, containing all eight amino acids. Most plant proteins are not complete, meaning they lack one or more amino acids. All eight have to be present for the consuming body to be able to use them for growth, repair and maintenance of all body systems, organs and function. Spirulina protein is easier to digest than meat protein. |

Non-essential amino acids (ie can be manufactured by the body if necessary) |
There are 10 non essential amino acids in Spirulina which support a range of different functions within the body, to do with the nervous system,the brain, cellular health and digestion |
||||||||||||||
Minerals |
POTASSIUM (15,400 mg/kg): A crucial mineral that regulates body electrolyte balance. Deficiency can cause heart arrest, hypertension, adrenal exhaustion and muscular collapse. |

Vitamins |
PYRIDOXINE or B6 (3 mg/kg): Involved in breakdown and assimilation of protein. Protects cardiac health, reduces oedema and stabilizes female hormone levels. Implicated in mental health |

Pigments: |
Chlorophyll – essential for photosynthesis within the plant. Involved in aiding digestion |

Carbohydrates |
Phytocyanin – responsible for Spirulina’s blue colour and is important as an immune system booster |
