Sustainably-Grown Spirulina Crunchies: Spirulina is a microscopic freshwater vegetable that gets its name from its tiny spiral shape. Spirulina's abundance of chlorophyll gives it a deep, emerald-green color. Rich in vitamin A as well as a good source of B vitamins and iron, spirulina is also made up of 75% protein including all nine essential amino acids. The Sunfood Difference Spirulina is grown in an isolated environment in Costa Rica without the use of pesticides or synthetic fertilizers, and is free of contaminants. After harvest, it is ground into a paste, pressed into spaghetti-like strands & gently air-dried at low temperatures. This revolutionary process creates the extraordinary crunch & flavor of Spirulina Crunchies.
