HelloPharmacist Scorecard of Arctic-Kelp 225 mcg by Country Life

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

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 1 active ingredient: iodine at 225 mcg per tablet. Iodine is a mineral your body needs to make thyroid hormones, which control metabolism and energy.

The tablet also contains inactive ingredients — cellulose, stearic acid, silica, and magnesium stearate — which are binders and fillers that hold the tablet together.

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: support healthy thyroid function.
  • We looked for evidence on: Iodine deficiency, Hyperthyroidism, Thyroid cancer, Thyroid storm, Thyroid hormone production, Goiter.
  • The strongest evidence on file: Iodine is rated "Likely Effective" for Iodine deficiency (Natural Medicines).
  • Also on file: Iodine is rated "Possibly Effective" for Thyroid storm.
  • Also on file: Iodine is rated "Insufficient Reliable Evidence To Rate" for Thyroid cancer, Hyperthyroidism.

The evidence shows iodine is likely effective for radiation exposure protection and iodine deficiency. It's possibly effective for oral mucositis (mouth sores from cancer treatment) and periodontitis (gum disease), though the data here is less robust.

For other uses, the evidence we hold isn't 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 in normal dietary amounts is well tolerated. High doses, though, can cause thyroid problems — both too much and too little thyroid function have been reported, along with nausea, diarrhea, headache, and a metallic taste.

In rare cases, people can have a hypersensitivity reaction to iodine itself, with symptoms like swelling, hives, fever, or enlarged lymph nodes. Taking large amounts over a long time has also caused acneform skin lesions in some cases.

Pregnancy and lactation require care. You do need adequate iodine in pregnancy, but only use the amount your doctor recommends — avoid high-dose products on your own.

Some iodine passes into breast milk, so follow medical guidance if you're breastfeeding. Talk with your doctor or pharmacist about the right dose for your situation.

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 doctor or pharmacist before starting if you take lithium, any antithyroid drugs (for overactive thyroid), or amiodarone (Cordarone), a heart medication. All three are Moderate interactions involving thyroid function.

Your healthcare provider may want to monitor your thyroid if you combine any of these with iodine.

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 supplement is useful if you need to shore up iodine intake or protect against radiation exposure. If you take lithium, antithyroid drugs, or amiodarone, talk with your doctor or pharmacist before starting — thyroid monitoring may be needed.

Stick to the dosage on the label and discuss it with your own healthcare provider to make sure it's right for you.

Each ingredient & the kinds of drugs it affects

For each ingredient in Arctic-Kelp 225 mcg 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.

Arctic-Kelp 225 mcg by Country Life: Common Questions

Does Arctic-Kelp 225 mcg by Country Life interact with any medications?
Yes. Based on its ingredients, Arctic-Kelp 225 mcg 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?
Arctic-Kelp 225 mcg 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 iodine safe to take during pregnancy?
Your body does need adequate iodine when you're pregnant, but the key is taking only the amount your doctor recommends — don't use a high-dose product on your own. Talk with your doctor about the right dose for you.
Can I take this while breastfeeding?
Some iodine does pass into breast milk, so you should follow medical guidance rather than decide on your own. Check with your doctor or pharmacist about the right amount while you're nursing.
What are the most common side effects?
At normal doses, iodine is well tolerated. At higher doses, people have reported abdominal upset, diarrhea, nausea, headache, a metallic taste, and in rare cases, hypersensitivity reactions like swelling or hives. If you notice any of these, stop and talk to your pharmacist.
Does iodine actually work for iodine deficiency?
Yes, iodine is likely effective for treating iodine deficiency. It's also likely effective for protecting against radiation exposure. For mouth sores and gum disease, the evidence is possibly effective but less established.
Can high doses cause thyroid problems?
Yes, iodine in high doses has been reported to cause both overactive and underactive thyroid, depending on your medical history. Stick to the label dose and don't exceed the tolerable upper intake level without medical supervision.
What's the difference between an iodine allergy and iodine sensitivity?
Many people labeled as having an "iodine allergy" are actually reacting to something else — like seafood proteins or contrast dye — not iodine itself. True iodine sensitivity to the mineral is less common but can happen, with symptoms like swelling, hives, or fever.
