Spirulina is a freshwater blue green algae, high in protein and chlorophyll. It is rich in naturally-occurring colloidal minerals, vitamins and enzymes. Spirulina is a “complete protein” whole food source, equal in value to animal protein, with all of the essential amino acids that the human body cannot manufacture, but are necessary for human life. Spirulina is a good source of “complete protein” if you are a vegetarian. A complete protein is necessary for stimulating growth hormone, which increases your immune system and protects your from infectious diseases, and growth hormone helps to repair damaged cells. Protein regulates blood sugar levels and controls hunger sensations. Protein is essential for all mental and physical functions, and can prevent mental and physical exhaustion. Mental intelligence is protein dependent.
