Kyoto Brand Chlorella is 100% certified pure Japanese chlorella with no added binders, fillers or coatings and is proven to deliver outstanding digestibility. Grown in the pristine waters of the Ishigaki-shi Islands of southern Japan, it is processed thorough exclusive technology that maintains chlorella's natural nutrients while breaking down the hard-to-digest cell wall. An independent laboratory study conducted by the Japan National Institute of Food Hygiene shows the digestibility of Kyoto Brand Chlorella to be 83% as opposed to 42% for the commonly available heat-treated chlorella and 38% for the untreated whole-cell chlorella.
