Claim These Lifesaving Tablets Before a Disaster Hits

Avoid These 2 Common "Prepper" Mistakes

Protecting your family from dangerous radiation is a smart move, especially if you know to watch out for these 2 common mistakes...

Customer Reviews: Folks Love These Tablets

I’m Not a Prepper… But I Bought These

"I’m not a prepper and I don’t buy survival products much. But the thought of my kids being exposed to radiation is so scary to me — and these tablets are priced so reasonably — that stocking up on them was a no-brainer.

I bought 8 packets of them for my family members and now I have a plan. The odds of the old nuclear plant a couple cities away becoming a threat are unlikely. But when it comes to something like radiation, I absolutely want to be ready. Thank you, 4Patriots.”


 Could These Tablets Get Better?!

"Could not have asked for a better product. Great for any medical kit! They came double packed to ensure freshness with a late expiration date! That in itself is AWESOME!!! What more can I say? If you are even considering getting something for possible radiation exposure, this should suffice."

Potassium Iodide tablets

The order was delivered very quickly. Only about a week after ordering. I am set for fallout protection for my thyroid.

Potassium Iodide Radiation-Blocking Tablets - 14-Day Supply

I bought this as insurance. Living near Chicago and O'Hare Airport, I wanted to have this as a "just in case". The info in your catalog is the same info I read in another publication, which also talked about surviving the shock wave. If things go wrong and the SHTF, this is something that will be very hard to find. The US doesn't have a stockpile and if something should happen, what is out there will probably go to military, first responders and healthcare workers. I keep this in my bugout bag. Hopefully, I will never need this but just in case, I'm covered.



Donna, thank you for sharing and we're so glad the Potassium Iodide Tablets bring you peace of mind and are also part of your bug out bag. Stay safe! Best Regards~Mandy

Laugh as you ruin Kissinger’s day

The proponents of “population control” failed to advance their agenda with the “vaccine”. Their time is limited, and disrupting the food supply takes too long. Henry Kissinger now likes the Neutron bomb. This hardens your body against it!



Hi Francis, Thank you for your review and feedback of our Potassium Iodide Radiation Blocking Tablets. Thank you for choosing 4Patriots for your survival needs! Best Regards, Kristy B. (publish

Potassium Iodide tablets

Bought these to add to our emergency supply because we live in close proximity to a nuclear power plant. You can't wait until something happens as it may be impossible to acquire the tablets at that time.



Howard, thanks for the positive review of the Potassium Iodide Tablets! Best Regards~Mandy

Radiation Blocking Tablets

If for no other reason but feeling you are prepared for the worse. I am so thankful that my family has not had to use these radiation tablets. However, I feel safer just knowing that my family would be protected in case that horrible day ever comes.



Thank you for your review Charlotte! We are so happy to know that you feel safer after purchasing the Potassium Iodide Radiation Blocking Tablets for your family. Best Regards ~Ashley
