1yr 10 month expiry date from purchase (March 2024)
One of the few supplier of 65mg Iodine tablets you can order in the uk, and also they are made in the uk. 65mg is equivalent to 65,000ug, many other 'high strength' tablets on Amazon are around 400ug, that's only 0.4mg, so don't get confused between mg and ug. Expiry date is 01/26, so a couple months less than 2 years, but reading this "potassium iodide pills are labelled with an expiration date, usually five or six years after manufacture. But their components are very stable, according to the Nuclear Regulatory Commission, and it is safe to take them after the expiration.....". So despite a relatively short under 2 years expiry date, they should be ok for at least another few years.

    Take two and take cover

    Timely delivery. Figured it was worth having on hand if things take a nasty turn what with whats happening with the Zaporizhzhya nuclear powerplant. Two tablets (130 mg) is the recommended single dose for most age groups so a bottle will easily provide for several families/friends.

    Truth be told if anything nuclear were to go down in Ukraine, it would be so far away that we should have plenty of warning. Still, government performance in the face of COVID-19 has been less than stellar and it is worth being prepared. Take only if instructed.

    The CDC has a nice page on Potassium Iodide if you need more information. Potassium Iodide works by the Wolff-Chaikoff effect blocking further uptake of iodine into the thyoird. With radiative dust, you are are far higher risk of ingesting and inhaling particles that get stuck in your body forever so seeking shelter and taking cover is more important than anything these tablets can do. All they do is prevent radioactive iodine being taken up by your thyoird. They protect no other organ/part of your body!

    N.B. if you are looking for daily iodine supplementation for dietary reasons this is absolutely the wrong dose (it's far too high!)

    Totally surprised to find so many reviews.. clearly I am not the only fruitloop in the house..Now that would have been funny a decade ago, but each day and week brings more stories of a world going through so many changes in almost every avenue of life, which makes cracks about fruit loops not even funny.

    If you are a prepper you need this.

    If you have a family you need this.

    If you are concerned about world events you need this

    If you live in Norfolk you should buy 2.

    At under £15 its the cheapest insurance.... and like all insurance you hope you never have to call on it.....

    It occurred to me to question the legitimacy of a product most people will never test or use until the unlikely event that their lives depend on it.

    The photo show the result of the test I performed with my kids. The bowl on the left contains a pulverized tablet, and some corn starch (I used resistant starch). The control bowl on the right only contained starch. I added a water solution of ozone produced by bubbling oozing through a bubble stone into ice water.

    The color change to the test bowl but not the control process that the tablet contained the iodide ion, which makes the product legitimate. Ozone oxidized iodide to iodine, which reacts with starch to create the purplish tint you observe in the photo.

    Buy this product with confidence. Obviously this isn'ta quantitative test, but the product isn't fake.

    I have an underperforming thyroid.The top thyroid doctors on youtube recommend that older people like me need milligrams of Iodine and not mcg, as the authorities recommend, and all supplements have.One youtube doctor has patients taking 30mg of Iodine.The tablets are soft and easily divided by a pill cutter.So I cut the tablets into quarters which I guess will be about 10mg Iodine,the rest being potassium.I think an intelligent person who takes too much Iodine will recognize the symptoms and back off.

    And the universal recommendation "consult your doctor"?Yeah right!We are up to our armpits in doctors here.
