KIKI's certified Organic Chlorella is carefully cultured, harvested and dried to retain as much of the nutritional properties as possible. The freshwater ponds are filled with carefully filtered water extracted from deep below the ground. Our chlorella is routinely tested for heavy metals, including mercury, lead and other contaminants to ensure that the finished product is completely pure. The cell walls are cracked to allow optimal digestion of the super-concentrated values from within each chlorella cell. No binders are used to produce KIKI's Chlorella Tablets, they contain only 100% pure chlorella powder which has been compressed into a tablet, completely free from binders, fillers and additives.
