KIKI’s Spirulina is a strain grown on a pennisula in Southern India surrounded by natural forests and away from urban areas. Our Spirulina is routinely tested for the presence of mercury, lead and other contaminants to ensure that our spirulina is as pure as possible. The spirulina is carefully dried through an evaporation method using low temperatures to preserve all the nutritional content. KIKI’s Spirulina Powder is certified and does not contain any fillers or additives of any kind.
