The ancient blue-green algae Spirulina originated in warm alkaline lakes in Africa and Central and South America, and was a prime source of protein for the Aztecs for centuries, verifying its safety and healthful effects on the body. Spirulina is a complete protein meaning it has all 8 essential amino acids and 10 non-essential ones that support good health.
Spirulina is actually 65-71% protein by weight, which is significantly more than protein found in beef, chicken or soybeans!
Spirulina has been used to treat allergies, ulcers, anemia, heavy-metal poisoning, and radiation poisoning. It is dense in vitamins, minerals, phytonutrients and carotenoid antioxidants that protect cells from damage. It contains B complex vitamins, beta-carotene, vitamin E, manganese, zinc, copper, iron, selenium, detoxifying chlorophyll and phycocyanin, as well as three anti-inflammatory essential fatty acids, gamma linolenic acid, linoleic acid, and arachidonic acid.
Animal and test tube studies have shown Spirulina to increase production of antibodies and other cells that improve immunity and help ward off infection and chronic illnesses such as cancer. It has even been shown to promote stem cell growth in mice!
