Chlorella is a nutrient-rich superfood derived from single-celled freshwater algae. Grown outdoors in freshwater with natural sunlight, our chlorella is rich in chlorophyll, giving it a vibrant emerald-green color. After harvesting, the chlorella is gently dried, and its cell walls are broken using a chemical-free technique for optimal absorption. The chlorella powder is then formed into convenient tablets, providing a natural source of vitamin D to support immunity.
