HelloPharmacist Scorecard of Potassium Iodide 85 mg by Dr. Berg

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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.

This product contains one active ingredient: potassium iodide, 85 mg per tablet. The remaining ingredients—microcrystalline cellulose, dicalcium phosphate, stearic acid, and magnesium stearate—are inactive fillers and binders that help form the tablet.

Does it work?

Couldn't assess
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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: protect against radiation exposure.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The product facts we hold do not include effectiveness data for potassium iodide.

The evidence, ingredient by ingredient Potassium

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.

Potassium from food is fine, but supplements can push your blood level into dangerous territory, especially if you have kidney disease. Gastrointestinal side effects—nausea, vomiting, abdominal pain, diarrhea, and gas—are the most common complaints.

Rarely, very high potassium causes arrhythmia (irregular heartbeat), heart block, low blood pressure (hypotension), and mental confusion. During pregnancy, dietary potassium is appropriate, but supplements should only be used under medical guidance.

The same holds for breastfeeding—talk with your doctor or pharmacist before taking a potassium supplement while nursing.

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 — Potassium.
  • The most serious interaction on file is rated Moderate.
  • For scale: 62 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 potassium-sparing diuretics, ACE inhibitors, and angiotensin receptor blockers (ARBs) before taking this product. All three carry Moderate risk of raising your blood potassium to unsafe levels.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you take a blood pressure medication—especially a diuretic, ACE inhibitor, or ARB—don't add potassium supplements without checking with your pharmacist or doctor first. Even if you don't take those drugs, kidney disease makes potassium supplementation riskier.

Potassium Iodide3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.
