Spirulina contains about 60% complete protein containing all essential amino acids, though with reduced amounts of methionine, cysteine and lysine when compared to the proteins of meat, eggs and milk. It is, however, superior to typical plant protein, such as that from legumes. Spirulina is a microscopic spiral shaped, blue-green vegetable algae. It has been used as a significant food source for centuries. Spirulina is highly digestible and the most nutritious, concentrated whole- food known to humankind. It is nature's richest whole-food source of complete protein. Rich in GLA, it also contains important B complexes including bio-available B12 and other essential organic, whole-food minerals and trace elements. Spirulina is also a source of potassium, calcium, chromium, copper, iron, magnesium, manganese, phosphorus, selenium, sodium and zinc
