HelloPharmacist Scorecard of Organic Iodine Liquid Drops Unflavored by Mary Ruth's

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 Aug 27, 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 has one active ingredient: iodine, an essential mineral your body needs to make thyroid hormones and support metabolism. The drops also contain organic vegetable glycerin and purified water as inactive ingredients to deliver the iodine in liquid form.

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: thyroid and iodine deficiency support.
  • We looked for evidence on: Iodine deficiency, Radiation exposure, Hypothyroidism, Thyroid function.
  • 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.

Iodine is likely effective for preventing thyroid problems after radiation exposure and for treating iodine deficiency. It's possibly effective for two oral conditions — oral mucositis (mouth ulcers and inflammation) 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.

Iodine is well tolerated at normal dietary amounts, but high doses can cause thyroid problems, goiter, and a condition called iododerma (acnelike skin lesions from chronic overuse). Some people are hypersensitive to iodine itself and can have serious reactions like hives, swelling, and in rare cases, anaphylaxis.

The pregnancy and breastfeeding data shows iodine is likely safe at appropriate doses — your body does need it — but possibly unsafe at high doses, so talk with your doctor about the right amount for you.

Side effects, ingredient by ingredient Iodine

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.

Before taking this product, check with your doctor if you take lithium (for mood disorders), antithyroid drugs like propylthiouracil or methimazole (for overactive thyroid), or amiodarone (a heart rhythm medication). All three carry Moderate-severity interaction risks with iodine — thyroid function changes and potential medication interference.

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.

This iodine supplement is useful if you're deficient or need protection after radiation exposure, and it's generally well tolerated at normal levels. If you take lithium, antithyroid drugs, or amiodarone, you'll need to clear it with your doctor first — iodine can interfere with how those work.

Check your medications and any thyroid history with your own doctor or pharmacist before you start.

Each ingredient & the kinds of drugs it affects

For each ingredient in Organic Iodine Liquid Drops Unflavored 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.

Iodine3 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.

Organic Iodine Liquid Drops Unflavored by Mary Ruth's: Common Questions

Does Organic Iodine Liquid Drops Unflavored by Mary Ruth's interact with any medications?
Yes. Based on its ingredients, Organic Iodine Liquid Drops Unflavored 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?
Organic Iodine Liquid Drops Unflavored 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.
Will this help if I don't have an iodine deficiency?
The data shows iodine is likely effective for radiation exposure and iodine deficiency specifically. For other uses like gum disease or oral ulcers, the evidence is less clear. Talk to your doctor about whether you actually need supplemental iodine — most people in the US get enough from salt and food.
Can I take this while pregnant or breastfeeding?
The safety data shows iodine is likely safe in pregnancy and breastfeeding at appropriate doses — your baby does need it — but it's possibly unsafe at high doses. Follow your doctor's guidance on how much to take; don't use high-dose products without medical advice.
What side effects should I watch for?
Most common ones are abdominal upset, nausea, diarrhea, headache, and a metallic taste. High doses or long-term use can cause thyroid problems, goiter, or acnelike skin lesions. Rare but serious reactions include hives, swelling, and anaphylaxis in people hypersensitive to iodine.
Is this safe if I have a shellfish or iodine allergy?
People often call a shellfish allergy an "iodine allergy," but shellfish contain proteins, not iodine itself. However, some people can be genuinely hypersensitive to iodine and have severe reactions. If you've had a reaction to iodine-containing drugs or supplements before, talk to your doctor before trying this.
How much iodine should I take?
The facts don't specify a dose for this product. Your doctor can tell you what's right based on your age, health, and why you're taking it — and to make sure it won't interfere with your other medications.
