Lugol's iodine, also known as aqueous iodine and strong iodine solution, is a solution of potassium iodide with iodine in water. It is a medication and disinfectant used for a number of purposes. Taken by mouth it is used to treat thyrotoxicosis until surgery can be carried out, protect the thyroid gland from radioactive iodine, and to treat iodine deficiency. When applied to the cervix it is used to help in screening for cervical cancer. As a disinfectant it may be applied to small wounds such as a needle stick injury. A small amount may also be used for emergency disinfection of drinking water. (must be used in accordance with physician's prescription) 

Calculating Number of MG's of Iodine and Iodide per Drop of Lugol's Solution 5%: Each VERTICAL "metric" drop (= 1/20 ml) is approximately 2.5 mg of iodine and 5 mg of potassium iodide. The Iodide portion of Potassium Iodide is about 75% so that is 3.75 mg. Therefore the total Iodine plus Iodide is 2.5 + 3.75 = 6.25 mg  and 2 drops is about 12.50 mg's of iodine/iodide (5.0 mg iodine, 7.50 mg iodide). Compared to iodine and potassium iodide tablets, J.CROW'S® Lugol's Solution offers big savings.

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.

Made from premium ingredients, the iodine used in J.CROW'S® Lugol's Solution is derived from mined crystals from 320 million year old natural brine deposits two miles beneath the earth's surface in Western USA (one of the few places in the world where such deposits exist).
