If you are a quality conscious consumer that cares about what goes in your body, then this iodine supplement is for you. Until today, finding a quality iodine supplement was almost impossible. With most sellers using unclear practices and no disclosure, a tremendous amount of research and risk is put on the consumer. This Lugol's has the highest quality standards available on the market. It is legally authorized for human consumption. Other sellers use legal disclaimers instead such as "not evaluated by the U.S. Food & Drug Administration," or "talisman only." We stand with confidence behind every drop of solution we produce because it has been procured and manufactured with the most rigorous international pharmaceutical standards. Our Lugol's Iodine Solution is laboratory manufactured under strict North American Good Manufacturing Practice (GMP) guidelines. Our Iodine originates from Atacama Salt Desert in northern Chile, where the largest, pristine reserves of the highest quality iodine on earth are found. It is extremely rare and difficult to import and comes in a "prilled" form, shaped like small little balls. It is USP/ACS/EP Grade which means it meets the standards for quality set by the United States Pharmacopeia Convention (USP), the American Chemical Society (ACS) and the European Pharmacopoeia (EP). Our Potassium Iodide is produced industrially in North America. Most solutions are made from kelp, an ocean source, but Potassium Iodide manufactured from kelp is well documented to be of lower quality, lower cost, and contain higher toxicity levels. Our Potassium Iodide is produced by treating potassium hydroxide with iodine, which causes the salt to form. It is USP grade and never sourced or imported from China, Japan or Russia.
