Bests & Worsts Reviews from Amazon

I have no idea whether these work and hope I never have a reason to find out. What I do know is that Vitamatic is an apparently reputable brand and these tablets are manufactured in the USA, so I feel comfortable relying on these if I never need to. For dosage information you should refer to the CDC's recommendations (google "CDC facts about potassium iodide"), but the short version is that if you're told to take them -- and only then -- the recommended dosage is 130 mg daily for adults (anyone at least 18) and for children at least 12 who weigh more than 150 pounds. For children 4-12 (and for those under 12-18 weighing 150 pounds or less) the recommended dosage is 65 mg, or half the "adult" dosage. And in all cases this is "for short-term use only (up to 10 days)" per the label on the bottle. Each tablet in these bottles contains a 65 mg dose, and each bottle contains 60 tablets, so a child would take one tablet a day and an adult two as appropriate, and that means each bottle represents a 10-day supply either for three adults or for two adults and two small children. Another reviewer stated that the listing is misleading because the front says there are 60 capsules in the bottle while the back says there are only 30, but that's not what it says. In fact, you can examine both sides of the label here on Amazon, and it clearly says on the back that a bottle contains 30 SERVINGS (not tablets) and that each serving is two tablets, so there's no discrepancy between the front and back: one tells how many tablets are in the bottle and the other identifies the number of adult "servings". Lastly, regarding the shelf life of these tablets, mine were received in July 2022 and have an expiration date of March 2025, so in theory they're only good for around two and a half years. However, if you research it you'll find that organizations including the FDA and Nuclear Regulatory Commission (NRC) determined the shelf life of potassium iodide (KI) tablets to be significantly longer than that when properly stored. For example, regarding whether it's safe to take expired tablets the answer on the NRC's "Frequently Asked Questions About Potassium Iodide" page says that they, "are inherently stable and do not lose their effectiveness over time". These are certainly affordable enough to replace every 2-3 years, but there's apparently no compelling need to do so if you're storing them the way you're supposed to. Anyway, I hope this information is helpful and that never have reason to take these tablets, but personally I'd rather have them and never need them than need them and not have them.
