In today’s increasingly unstable world, the possibility of nuclear conflict always looms in the background. Whether it’s escalating tensions with Russia, China, North Korea, or rogue actors, a nuclear event is one of the most devastating disasters we could face. Even if you survive the initial blast, you still have to deal with one of the deadliest long-term dangers: nuclear fallout.
Radiation exposure from fallout can lead to serious health problems, but there are a few over-the-counter (OTC) items that might help reduce how much radiation your body absorbs. In this video, Reality Survival & Prepping shares 9 OTC products you can stock up on now, just in case.
While these aren’t cures, and they won’t magically make radiation safe, they may help limit absorption of radioactive isotopes, and that could be a life-saving difference. Below you can watch video and find his list of 9 recommended OTC items. As always, this is not medical advice; it’s informational only.

1. Apple Pectin
According to some studies, apple pectin may help bind to radioactive cesium in the body. It works as a natural chelating agent (substances that attach to heavy metals and help flush them out). While evidence is mostly focused on cesium-137, it’s easy to find and cheap to store.
Not a cure-all, but it’s worth having if radioactive cesium is part of the fallout.
2. Iodine Pills (Potassium Iodide / IOSAT)
This is one of the only FDA-approved treatments for radiation exposure. Iodine pills (like IOSAT) flood your thyroid with stable iodine, blocking the uptake of radioactive iodine-131, which is common in nuclear fallout.
Crucial for protecting your thyroid. Everyone should have this in their preps.
3. TUMS (Calcium Carbonate)
The calcium in TUMS may help block the absorption of radioactive strontium and radium in your gut by saturating your system with safe calcium. This limits the space available for your body to absorb the dangerous versions.
Cheap, easy to find, and actually helpful beyond indigestion.
4. Gaviscon (Aluminum Hydroxide & Sodium Alginate)
Gaviscon contains two ingredients that may bind radioactive materials in your digestive system:
- Aluminum hydroxide: Binds to strontium and radium
- Sodium alginate: Helps remove radioactive isotopes from the body
If you’re only buying one antacid for radiation preps, this is the one to get.
5. Baking Soda (Sodium Bicarbonate)
Baking soda may help flush uranium from the kidneys. It’s believed to reduce the body’s ability to absorb uranium and aid in its removal via urine.
Also good for general prepping, so stock up regardless.
6. Vitamin C (Ascorbic Acid)
Radiation causes oxidative stress, which is often described as cellular rusting. Vitamin C is a powerful antioxidant that might reduce this damage. High doses may help in a crisis, but daily mega-doses aren’t advised for long-term use.
During a fallout situation, consider taking more than usual, but for short periods only.
7. Melatonin
Yes, it helps you sleep, but melatonin is also a strong antioxidant. Radiation exposure disrupts sleep and weakens your body’s ability to recover. Melatonin may help mitigate both problems.
Double benefit: antioxidant + better sleep in a high-stress disaster.
8. Multivitamins
Multivitamins contain minerals like calcium, iodine, magnesium, zinc, and iron, all of which help fill your body with stable elements that radioactive versions mimic. Keeping your mineral levels topped off can reduce how much radioactive material your body absorbs.
Don’t overthink it — just make sure your multivitamin has the basics.
9. Seaweed
Seaweed, especially kelp, is rich in natural iodine, and some varieties also contain alginate, which helps remove radioactive elements. It won’t replace potassium iodide tablets, but it can supplement your iodine intake naturally.
A good dietary backup, and a potential barter item in a crisis.
Bonus Tip: Drink More Water
Drinking 3 to 4 liters of water per day can help flush tritium, a radioactive form of hydrogen, from your body. It’s one of the simplest ways to detox after exposure.
Final Thoughts
None of these items will make radiation harmless, but they could reduce your risk of long-term health issues if taken after exposure. Most of them are affordable, easy to find, and have everyday uses anyway, so it makes sense to include them in your prepping supplies.
