The Source Spirulina was originally discovered growing naturally on unpolluted alkaline lakes in Central Africa and Mexico where it was integrated into the diet of the mighty Aztec empire. Today, Spirulina is ecologically and organically grown in large cultivated ponds around the world. On a weight for weight basis, Spirulina is nature’s richest and most complete source of nutrition. This green superfood, containing over 100 synergistic nutrients, comes from a microscopic freshwater plant, ecologically grown without chemicals and concentrated by removing nothing but the water. Spirulina is widely used throughout the world as a food supplement that may maintain health, energy and optimum weight.
