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.

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.

Mary Ruth's Organic Iodine Liquid Drops is a straightforward single-ingredient supplement: iodine in liquid form. The inactive ingredients are glycerin and purified water — the iodine is dissolved in them so you can take it by the drop.

Iodine is an essential mineral your body needs to make thyroid hormones, which control your metabolism and energy. This product is meant to fill that gap if your diet doesn't have enough iodine-rich foods like seafood and dairy.

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 support and metabolism regulation.
  • We looked for evidence on: Iodine deficiency, Infant development, Prematurity, Radiation exposure, Thyroid function, Metabolic health.
  • 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 is rated likely effective for preventing and treating iodine deficiency, and for protecting the thyroid after radiation exposure. It's also rated possibly effective for mouth sores (oral mucositis) and gum disease (periodontitis), though the evidence for those uses is less robust.

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 generally well tolerated when you take normal dietary amounts. The safety notes advise caution with high doses — they can cause thyroid problems, including an overactive or underactive thyroid, goiter (an enlarged thyroid), and a metallic taste in your mouth.

A small number of people may have hypersensitivity reactions, including rash, fever, or in rare cases severe allergic reactions. In pregnancy and breastfeeding, some iodine is necessary, but you should only take the amount your doctor advises and avoid high-dose products.

Excess iodine can pass into breast milk. If you're pregnant or nursing, talk with your doctor or pharmacist about the right dose 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.

Check with your pharmacist if you take lithium, any antithyroid drugs (like propylthiouracil or methimazole), or amiodarone — all have Moderate-severity interactions with iodine and require thyroid monitoring if you combine them. All three affect how your thyroid works, and adding iodine can compound that risk.

Check your own medication Run your meds through the checker above

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 product is useful if you have an iodine deficiency and your doctor confirms that. If you take lithium, antithyroid drugs, or amiodarone, you need to check with your pharmacist first — iodine can interfere with how these work.

Even if you don't take those medications, high doses can cause thyroid problems, so stick to normal dietary amounts unless your doctor says otherwise.

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.
Can I take this if I'm pregnant or breastfeeding?
Iodine is necessary during pregnancy and while nursing, but you should only take the amount your doctor recommends and avoid high-dose products. Excess iodine passes into breast milk. Talk with your doctor or pharmacist to figure out the right dose for you — it's an individual decision based on your needs.
What are the most common side effects?
When taken in normal amounts, iodine is well tolerated. At higher doses, people have reported nausea, diarrhea, headache, a metallic taste, and in some cases thyroid problems like an overactive or underactive thyroid. A small number of people may have allergic reactions with rash or swelling.
Does this really work for iodine deficiency?
Yes — iodine is rated likely effective for preventing and treating iodine deficiency. It's also likely effective for protecting your thyroid after radiation exposure. If you suspect you're deficient, your doctor can test your iodine level and tell you if this is right for you.
What is iodine and why do I need it?
Iodine is a mineral your body uses to make thyroid hormones, which regulate your metabolism and energy. Most people get enough from seafood, dairy, and eggs, but if your diet is low in these foods, a supplement might help. Talk with your doctor if you think you might be deficient.
Can I take high doses of this to work better?
No — high doses of iodine can cause thyroid problems, including an overactive or underactive thyroid, and may cause acne-like skin lesions. Stick to the amount your doctor or the label recommends. More is not better with iodine.
What's in this besides the iodine?
The inactive ingredients are glycerin and purified water — they're there so the iodine can be mixed into a liquid drop form. There are no fillers or binders beyond those.
