How many packs should I stockpile?

Storing at least one pack (14 tablets) PER person for each location frequented (home, 2nd home, relative’s home, childcare, office, etc.) is our recommendation. Iosat Potassium Iodide tablets should be immediately available in the event of a nuclear radiation emergency. To be most effective, the first dose should be taken no later than 2-3 hours prior to potential exposure to radioactive iodine (as directed by public health officials). Then, one dose every day (same time) until your family has evacuated to an uncontaminated area, and then stop taking the tablets (as directed by public health officials). Any remaining tablets will still be foil-sealed and available for a future need.

  1. Walt Hayes

    Sealed packaging. Received in two days. Freshest stock I found on the net.

  2. C Zais

    I bought from this company 7 years ago, but those just now expired. Owner is VERY informative about potassium iodide and radiation. Got my replacements in two days.

  3. Truc Lahilahi

    Shipped to Hawaii fast! Owner spoke to me for over 20 minutes answering questions and actually talked me into buying less. Impressed.

  4. Audrey_Grant

    These were included in kits we bought from – Hope to never need them, but they have a long expiration date, so worth it.

  5. Jared Wilbur

    Have bought from this supplier several times and product always comes quickly and securely packed. Longest expiration dates I’ve found online and good info on the site.
