Chlorella are green, single-cell micro-algae and perhaps the world's most nutritious food. Chlorella is the only source of "Chlorella Growth Factor" (CGF), the richest source of chlorophyll and over 50% protein. Our chlorella is carefully cultured, harvested, and dried at low temperature. The cell walls are broken to allow optimal assimilation of the super-concentrated nutrition from within each chlorella cell. *
