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 2 of its 2 active ingredients.
  • “Total Iodine/Iodide” is listed as a grouped ingredient — the label gives one combined amount (50 mg) without saying how much of each component you get.

Iodoral IOD-50 contains 2 active ingredients: iodine and iodide (the two main forms of this mineral). The product also includes inactive ingredients—microcrystalline cellulose, vegetable stearins, pharmaceutical glaze, and Micosolle—which serve as binders, flow agents, and capsule coating.

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: iodine supplementation for nutrient deficiency.
  • We looked for evidence on: Iodine deficiency, Infant development, Prematurity, Radiation exposure, Thyroid function, Goiter.
  • 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.
  • Also on file: Iodine is rated "Possibly Ineffective" for Prematurity.

Iodine in this product is rated Likely Effective for preventing thyroid problems after radiation exposure and for treating iodine deficiency. It's rated Possibly Effective for oral mucositis (mouth sores from cancer treatment) and periodontitis (gum disease), though the evidence for those uses is less established.

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.

When taken in normal dietary amounts and with proper medical oversight, iodine is generally well tolerated. The most common side effects are stomach upset, diarrhea, headache, nausea, and a metallic taste.

High doses—especially over a long period—can cause thyroid problems (both overactivity and underactivity), goiter (enlarged thyroid), or acnelike skin lesions called iododerma. Rare serious reactions include severe allergic responses.

In pregnancy, adequate iodine is important for your baby's development, but use only the dose your doctor recommends and avoid high-dose products. In breastfeeding, some iodine passes into breast milk, so follow your healthcare provider's guidance.

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.

Check with your doctor or pharmacist before using this product if you take lithium, any antithyroid drugs (such as propylthiouracil or methimazole), or amiodarone. All three interactions are Moderate severity and involve thyroid function or iodine level buildup—your provider may want to monitor your thyroid blood work more often.

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.

Iodoral IOD-50 is useful if you need iodine supplementation after radiation exposure or have a confirmed iodine deficiency, especially with medical supervision. If you take lithium, antithyroid drugs, or amiodarone, talk with your doctor or pharmacist before starting—your thyroid function may need monitoring.

Because high doses carry thyroid and skin risks, use only the amount your healthcare provider advises.

Total Iodine/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.
