$50 · J Crows Lugols Iodine twin pack

Calculating Number of MG's of Iodine and Iodide per Drop of LUGOL'S 2%: Each VERTICAL "metric" drop (= 1/20 ml) is approximately 1.0 mg of iodine and 2.0 mg of potassium iodide. The Iodide portion of Potassium Iodide is about 75% so that is 1.5 mg. Therefore the total Iodine plus Iodide is 1.0 + 1.5 = 2.5 mg and 2 drops is about 5.0 mg's of iodine/iodide (2.0 mg iodine, 3.0 mg iodide). Compared to iodine and potassium iodide tablets, J.CROW'S® Lugol's Solution offers big savings. Approximately 1200 vertical drops per 2 oz. container. To use as a water purifier add 3-6 drops per liter of water. Does not expire. Store at room temperature out of direct sunlight. No need to refrigerate. FREE empty used quality glass droppers need to be sterilized to reuse
