Spirulina is a single-cell, blue green algae that multiplies in warm, alkaline bodies of fresh water. The name is derived from the Latin word for 'helix' or 'spiral' due to the physical configuration of the organism as it forms swirling, microscopic strands. Spirulina is one of the cleanest, naturally sterile foods found in nature. The ability of Spirulina to grow in hot alkaline environments ensures its hygienic status, as no other organisms can survive to pollute the waters in which the algae grows. Spirulina contains the highest concentration in the world of beta carotene (many more times than carrots!), vitamin B-12 and gamma linolenic acid (GLA). It also contains almost all of the known amino acids and all nine essential amino acids that the body must derive from food. It contains all trace minerals and the essential fatty acids. It contains 250% more B-12 than liver. It is 65-71% protein as compared to beef protein. It contains 26 times the calcium of milk, is high in niacin, phosphorus, chlorophyll and iron. The only thing it lacks is carbohydrates. It is the complete food.
