Spirulina is a single-cell blue-green algae that grows and flourished in warm, fresh bodies of water throughout the world. It is renowned for it's extremely high percentage of complete protein (~60% -- over twice as much as beef!) and it's containment of every essential amino acid. Spirulina also contains a myriad of naturally-occurring vitamins and minerals including Vitamins A, B1 (Thiamine), B2 (Riboflavin), B3 (Nicotinamide), B6 (Pyridoxine), B9 (Folic Acid), C, D, E, as well as Potassium, Calcium, Chromium, Copper, Iron, Magnesium, Manganese, Phosphorous, Selenium, Sodium and Zinc. As a Superfood, Spirulina's lipid content is about 7% by weight, and it is rich in gamma-linolenic acid (GLA), and also provides alpha-linolenic acid (ALA), linoleic acid (LA), stearidonic acid (SDA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and arachidonic acid (AA). Spirulina also contains many pigments which may be beneficial and bioavailable, including beta-carotene, zeaxanthin, chlorophyll-a, xanthophyll, echinenone, myxoxanthophyll, canthaxanthin, diatoxanthin, 3'-hydroxyechinenone, beta-cryptoxanthin and oscillaxanthin, plus the phycobiliproteins c-phycocyanin and allophycocyanin. Recent scientific studies show Spirulina creating a protection against hay fever, as well as exhibiting substantial benefits towards the reduction of blood pressure and cholesterol, including increased HDL (good) cholesterol and lowered triglycerides. Spirulina has also been shown to increase weight gain and antioxidants in malnourished children and the elderly. Spirulina was consumed as food source by the ancient Aztecs and other Mesopotamians as far back as the 16th Century, and it can even be given as a supplement to your dogs, cats and horses to enhance the nutrients in their diets.
