INCI: Arthrospira plantensis Certified Organic Kosher Certified Origin: United States. Description: For centuries, the native peoples of Mexico, Africa, and Asia have eaten spirulina and made it one of their major sources of protein. The blue-green algae is plentiful in lakes and inland bodies of water that are warm and alkaline. The plant's chemical makeup is 65% amino acids, including the essential fatty acid gamma-linolenic acid (GLA). The high concentration of amino acids has made spirulina a popular nutritional supplement for those who are unable to obtain sufficient calories and protein through diet alone, particularly athletes who burn calories at a high rate. In addition to amino acids, spirulina is also a rich source of numerous other nutrients, including many essential vitamins and minerals.
