Before purchasing Potassium Iodide, you must CLICK HERE to read what the CDC/FDA has to say!


When radioactive iodine is released into the air either through a nuclear explosion or a leak from a nuclear power plant or stored radioactive materials, it can easily enter the thyroid and damage it. Depending upon prevailing winds the amount of radioactive iodine released and a myriad other factors, people can be at risk even at 200+ miles from the source (e.g. Chernobyl). Children are especially susceptible.

By taking potassium iodide (KI) at such a time (in the amounts and for the length of time indicated below), it will fill up your thyroid, blocking radioactive iodine from entering. Read an excerpt about this from Kearny's Nuclear War Suvival Skills!

Also, check out our brand new (as of April 25, 2011) Nuclear Disaster Preparedness Kit ("Nuke Kit").

DISCLAIMER: SunstoneFormulas.com only sells the chemical compound KI and not the medicine that the consumer may choose to make as described below and in much more detail in Kearny's book. Most of the information we present about KI comes from this same book. We advise our customers to purchase the book to get a complete understanding of how to use KI in nuclear emergencies, as well as to gain other important skills and knowledge associated with surviving nuclear disasters!

Recommended Use:
DURING AN EMERGENCY THIS 40 GRAMS OF KI MIXED WITH WATER PROVIDES A 14-DAY SUPPLY FOR 20 ADULTS AT 4 DROPS PER DAY PER PERSON (130 mg KI). Potassium iodide should be taken as soon as possible after you are told to take it by public health officials.  NOTE:  DO NOT TAKE KI UNTIL AND UNLESS PUBLIC HEALTH OFFICIALS IN YOUR AREA TELL YOU TO! Take one dose every 24 hours. More will not help you, because the thyroid can hold only limited amounts of iodine. For some few people, larger doses may increase the risk of side effects. Take it daily until the situation is officially pronounced safe, up to a MAXIMUM of 14 (fourteen) consecutive days.


Preparation of the Liquid KI:
Prepare as follows: Pour safe room-temperature water into the 2-fluid-ounce bottle containing the granular potassium iodide until it's about 90% full. Then close the lid tightly and shake the bottle vigorously for at least 2 minutes. The recommended daily dose of this solution is:

  • 4 drops (i.e. 130 mg) for adults. 
  • Children between 3 and 18 years of age should take 65 mg or two drops.
  • Children who are adult size (greater than or equal to 150 pounds) should take the full adult dose, regardless of their age.
  • Infants and children between 1 month and 3 years of age should take 32 mg or 1 drop. This dose is for both nursing and non-nursing infants and children.
  • Newborns from birth to 1 month of age should be given 16 mg. This dose is for both nursing and non-nursing newborn infants.

For additional information on doses, please read the CDC article HERE.

Storage and Shelf Life:
Store at room temperature away from light. This product will hold its potency for 6 to 10 years depending upon its storage conditions. Highly recommended that you purchase a new supply of KI in 6 to 10 years and discard the old supply. (Please read the DISCLAIMER above!)

40 grams of 100% pure USP-grade chemical compound Potassium Iodide (KI) in a 2 oz bottle + plastic dropper. When the 2 oz bottle is filled with the KI mixed in water (as described above) it provides a 14-day supply for 20 adults (4 drops per day).

Pregnant Women: Because all forms of iodine cross the placenta, pregnant women should take KI to protect the growing fetus. However, pregnant women should take only one dose of KI following internal contamination with (or likely internal contamination with) radioactive iodine.

Breastfeeding Women: Women who are breastfeeding should take only one dose of KI if they have been internally contaminated with (or are likely to be internally contaminated with) radioactive iodine. Because radioactive iodine quickly gets into breast milk, CDC recommends that women internally contaminated with (or are likely to be internally contaminated with) radioactive iodine stop breastfeeding and feed their child baby formula or other food if it is available. If breast milk is the only food available for an infant, nursing should continue.


Infants (including breast-fed infants): Infants need to be given the recommended dosage of KI for babies (see How much KI should I take?). The amount of KI that gets into breast milk is not enough to protect breast-fed infants from exposure to radioactive iodine. The proper dose of KI given to a nursing infant will help protect it from radioactive iodine that it breathes in or drinks in breast milk.
