Spirulina Nutrition Information

Spirulina is a microscopic plankton, or algae, that is nutritionally suitable as a food source. It contains protein, vitamins and minerals, enzymes, carbohydrates and fats necessary for human life. Dr. Christopher Hills and Dr. Hiroshi Nakamura formed the Microalgae International Union to study spirulina and other microalgae as a cure for the world food and energy crisis. While their work has been overlooked by some, it has been recognized by the United Nations as a potential "solution to the world protein shortage."

  1. Protein in Spirulina

    • Spirulina contains 18 of the 22 amino acids that build the proteins required by the human body, including the nine essential amino acids that cannot be produced by the body. This classifies it as a complete protein. The amino acids in spirulina are available in the proper ratio for use by the human body. Since spirulina is up to 95 percent digestible by the human body, 1 oz. of spirulina supplies about 16g of protein. In comparison, 1 oz. of soybeans contains 3g of incomplete protein.

    Vitamins and Minerals

    • Spirulina is a valuable source of vitamins and minerals, containing generous amounts of calcium; vitamins A, B1, B2, B3, B6, B9, B12, C, D and E; folic acid; iron; potassium; chromium; copper; magnesium; and zinc. Spirulina also is a rich source of green chlorophyll, essential to the production of red blood cells.

    Carbohydrates

    • Spirulina also is a valuable source of carbohydrates, containing glycogen that is ready for use by the human body. It also contains other carbohydrates, including glycosides and bioflavonoids, which are important to body processes. Spirulina contains 381 calories per 100g, and many of those calories are available as energy from carbohydrates.

    Omega-3 and Omega-6 Fatty Acids

    • Spirulina is an important vegetarian source of omega-3 and omega-6 fatty acids. These fatty acids, which cannot be made by the body and are considered essential to the human diet, may help to reduce cholesterol levels and protect the body against disease.

    Spirulina and the Immune System

    • According to immunologists at the University of California Davis School of Medicine and Medical Center, spirulina benefits the immune system and protects against pathogens. It can potentially protect the body against infections and parasites.

      Spirulina is a controversial supplement, with proponents claiming healing effects on many diseases, while others claim there are no therapeutic effects. More research is needed on the beneficial effects of spirulina against disease and its possible healing properties.
