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."

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.

Secure future.

Iodide is used to protect your thyroid in the event of a radiation event, such as a dirty bomb, nuclear power generation lack or melt downs. It does make your security stronger even if it only gives you time to reach a secure location away from further exposure. Having in hand does generate peace of mind. Heaven help us if we ever do have to use it. I have enough stored to supply me and my family and some friends.



Gary, thanks for writing us a great review! We love hearing our products bring you and your family peace of mind. Best Regards~Mandy

Great comfort knowing I have them on hand for an emergency!

I received my 2 orders of Radiation Blocking tablets in only a few days. I got 14 tablets for myself and 14 for my husband. It is such a comfort to know that I have this life saving medication on hand if there is ever a need for it. Living in a rural city, there is little guarantee that there will be a supply available if such an emergency occurs. We will be prepared!



Barb, thank you so much for an awesome review! Great to know you entrust our products to keep you safe if an emergency should ever happen! Best Regards, Mandy

Amazing Beam on Solar Flash light

First time I just bought one by itself, should have bought 4 at once! Would have saved myself the second shipping cost. The spot light it really powerful. Has the red LED flashing light makes you highly visible walking or if you have roadside emergency. Just sit on my dash in the sun or using the USB cord to charge. I have been giving as gifts.



Thank you for your review, James! Thank you for taking the time to leave a review for us at 4Patriots, LLC. We're happy we could meet your expectations! Best Regards, Kristy B.

My Reason Why !!

After a nuclear radiation emergency/I must have these available to take so that the weird physical things that can happen to me and my family after a Nuclear Hit. Have you not seen the films after WW11 after the bomb we sank on Japan? It was devastating for those that lived. I'm going to be prepared for this to happen as we too many enemies. A-Bomb is one way to achieve their captivity of us.



Hi Suzanne, We appreciate your feedback. We hope that the Potassium Iodide Radiation Tablets work well for you. Best, Ashley

Iodine tablets radiation blocking

The volatility in the world made me think it might be a good idea to have packages of tablets for my family member and I. Seeing how the stores run out of provisions when something happens was another point to consider. I want to be able to provide as much as I can for my family just in case something happens. Better to be safe than sorry.
