Our quest for the cleanest spirulina in the world brought us to a remote farm in Southern California, far from highways, airports, and cities. Clean air and mineral-rich water yield premium spirulina while a closed-loop water and nutrient recycling process ensures sustainable sourcing. It gets better. Spirulina contains up to 15x more beta-carotene than carrots, up to 1.5x more calcium than milk, and more iron than spinach, delivering an absolute superfood powerhouse in a convenient powder.
