In 1976, a group of U.S. visionary pioneers founded the Proteus Corporation to develop spirulina, a blue-green algae, as a world food resource. This team began cultivation in a hot desert area in Southeastern California and later changed the company’s name to Earthrise Nutritionals.

Since 2005, Earthrise Nutritionals is wholly owned by our parent company DIC. Discover the source of our natural blue colorant LINABLUE® by taking a virtual tour of our California Spirulina farm – the largest in the world.
