HelloPharmacist Scorecard of Potassium Iodide by Lidtke Military

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Lidtke Military Potassium Iodide is a single-ingredient product containing potassium iodide, the bioavailable form of iodine your body needs. It also contains several inactive ingredients — dicalcium phosphate, microcrystalline cellulose, stearic acid, magnesium stearate, pharmaceutical glaze, and talc — which are fillers and binders that help form and stabilize the tablet.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: promote beneficial iodide levels in thyroid gland.
  • We looked for evidence on: Iodine deficiency, Radiation exposure, Thyroid function, Iodine status.
  • The strongest evidence on file: Iodine is rated "Likely Effective" for Radiation exposure (Natural Medicines).
  • Also on file: Iodine is rated "Likely Effective" for Iodine deficiency.

Potassium iodide is likely effective for preventing thyroid problems after radiation exposure and for correcting iodine deficiency. It's possibly effective for oral mucositis (mouth sore inflammation) and periodontitis (gum disease), though the evidence for those uses is less established.

The dose and duration matter a lot — and so does medical supervision, especially if you have a thyroid condition.

The evidence, ingredient by ingredient Iodine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Iodine is well tolerated in normal dietary amounts, but high doses can cause thyroid problems, including overactive thyroid (hyperthyroidism), underactive thyroid (hypothyroidism), and thyroid growths. Most common side effects when taken orally include upset stomach, diarrhea, headache, metallic taste, and nausea.

Serious allergic reactions (anaphylaxis) and other hypersensitivity reactions are rare but possible; symptoms include swelling of deeper skin and lip tissue, fever, swollen lymph nodes, and rash. In pregnancy, adequate iodine is important for the baby's development, but use only the amount your doctor advises and avoid high-dose products.

During breastfeeding, some iodine passes into breast milk, so follow your doctor's guidance. If you take this product chronically or in very high amounts, a rare acne-like skin condition called iododerma may develop — it cleared after stopping in reported cases.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Iodine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: lithium.
  • For scale: 7 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Double-check this product with your doctor or pharmacist before taking it if you use lithium, any antithyroid drug, or amiodarone — all three carry Moderate-severity interactions that can affect your thyroid. These are the main medication types to watch.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Potassium iodide works well for radiation protection and fixing iodine deficiency when used as directed. If you take lithium, antithyroid drugs, or amiodarone, you need to check with your doctor or pharmacist first — the interactions are real and thyroid monitoring may be needed.

Talk it over with them before you start.

Each ingredient & the kinds of drugs it affects

For each ingredient in Potassium Iodide with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Potassium Iodide3 drug types · 7 drugs

Amiodarone (Cordarone)

Combining iodine with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with iodine might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Iodine might alter the effects of antithyroid drugs.
Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking iodine while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Probable Evidence D
Lithium

Combining iodine with lithium might have additive hypothyroid effects.
Lithium can inhibit thyroid function. Several case reports suggest that concomitant use of lithium and potassium iodide can reduce thyroid function in otherwise healthy adults. Monitor thyroid function.

Does Potassium Iodide by Lidtke Military interact with any medications?
Yes. Based on its ingredients, Potassium Iodide has a known interaction with 7 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Potassium Iodide contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is potassium iodide safe to take during pregnancy?
Adequate iodine is important in pregnancy for your baby's development, but the safety data says to use only the amount your doctor advises and avoid high-dose products. Talk with your doctor or pharmacist about the right dose for you — it's an individual decision based on your needs.
Can I take this while breastfeeding?
Some iodine does pass into breast milk. The safety data advises following medical guidance on how much to take. Check with your doctor or pharmacist about what's right for your situation.
What are the most common side effects?
The most common ones are upset stomach, diarrhea, headache, metallic taste, and nausea. They tend to be mild and happen when iodine is taken in high amounts or over a long time. Serious allergic reactions are rare.
Will this product prevent radiation exposure?
Potassium iodide is likely effective at protecting your thyroid after radiation exposure — it works by blocking the thyroid's uptake of radioactive iodine. Timing matters; it needs to be taken before or very soon after exposure, and your doctor will advise you on dose and when to use it.
Can I take this if I have a thyroid condition?
It depends on your specific condition. High-dose iodine can cause both overactive and underactive thyroid depending on your history. Talk with your doctor or pharmacist — they'll need to know your thyroid status and monitor you if you take it.
