Savely Yurkovsky MD a US doctor (whose book BIOLOGICAL, CHEMICAL AND NUCLEAR WARFARE – on surviving nuclear disasters, biological warfare etc) states that the standard Potassium Iodide (KI) pills issued to authorities in states with nuclear reactors contain 130 mg of KI each. This is the dose for adults 18 years and over. Children’s dosages are lower. (4 -12 year olds are recommended to have 1/2 a 130 mg KI tablet.)
In the Clinicians Brand (FROM NZ) Iodine Oral Drops, there are 250 mcg in a drop, and approximately 15 drops in a dropper full. Each dropperful therefore contains 2750 mcg (3.75 mg).
So about 30 ml of the solution will contain about 101.5 mg of KI.
There is a risk of side effects of high iodine dosages including iodism and potential for allergic reaction, as explained below:
“Thyroid function remains unchanged in 99 percent of patients. Untoward effects of iodine, allergies, swelling of the salivary glands and thyroid, and iodism, occur rarely, in less than 1 percent. Iodine removes the toxic halogens fluoride and bromide from the body. Iodism, an unpleasant brassy taste, runny nose, and acne-like skin lesions, is caused by the bromide that iodine extracts from the tissues. Symptoms subside on a lesser dose of iodine.”
There is also a potential risk of paradoxical suppression of the thyroid gland with large doses of iodine.
However, most people seem to tolerate iodine well.
This article explains some of the recent research and gives a discussion of dosages and iodine’s wide ranging effects and I suggest you read this before making a decision about how much to take.
At present my plan is to take about 12.5 mg right now.
Iodine should be taken for as long as exposure continues so this is why I taking a “smaller” dose now as I will probably take this amount for at least several days.
