HelloPharmacist Scorecard of Arctic Cod Liver Oil Lemon by Nordic Naturals

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 4 of its 4 active ingredients.
  • “Total Omega-3 Fatty Acids” is listed as a grouped ingredient — the label gives one combined amount (1,060 mg) without saying how much of each component you get.

This liquid contains 4 active ingredients: eicosapentaenoic acid and docosahexaenoic acid (the two main omega-3 fatty acids in fish oil), vitamin A, and total omega-3 fatty acids. The inactive ingredients include purified Arctic cod liver oil, natural lemon flavor, vitamin E (D-alpha-tocopherol), and rosemary extract.

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: heart, brain, nervous system, immune support.
  • We looked for evidence on: Cognitive function, Vitamin A deficiency, Night vision, Acne, Aging skin, Wrinkled skin — and 4 related terms.
  • The strongest evidence on file: Vitamin A is rated "Effective" for Vitamin A deficiency (Natural Medicines).
  • Also on file: Vitamin A is rated "Possibly Effective" for Aging skin, Night vision, Wrinkled skin.
  • Also on file: Vitamin A is rated "Insufficient Reliable Evidence To Rate" for Acne, Cognitive function, Atopic dermatitis (eczema).

Vitamin A in this product is effective for preventing vitamin A deficiency. It's possibly effective for oral leukoplakia (a precancerous mouth condition), aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia (a lung condition in premature infants).

We don't have established evidence in our data for the omega-3 components' effectiveness.

The evidence, ingredient by ingredient Vitamin A

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.

Vitamin A is generally well tolerated at recommended doses, but it builds up in your body, so high doses carry a risk of toxicity — which can cause liver damage, headache, blurred vision, dry skin, hair loss, and in very rare cases, serious neurological effects. The safety data notes that high-dose vitamin A (especially as retinol) in pregnancy can cause birth defects and should be avoided; normal dietary and recommended supplement amounts are appropriate.

We don't have safety data on file for the omega-3 components.

Side effects, ingredient by ingredient Vitamin A

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin A.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 388 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 you start, double-check with your doctor or pharmacist if you take retinoid medications (Major interaction), blood thinners like warfarin, tetracycline antibiotics, or any drugs known to be hard on the liver (all Moderate interactions). Altogether, these interactions span 388 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

This product may work well for you if you're deficient in vitamin A or looking for omega-3 support, but if you take retinoid medications (like Accutane), blood thinners, tetracycline antibiotics, or drugs that stress your liver, you'll want to talk it over with your doctor or pharmacist before starting — especially since vitamin A toxicity is a real risk at high doses.

Each ingredient & the kinds of drugs it affects

For each ingredient in Arctic Cod Liver Oil Lemon 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.

Vitamin A4 drug types · 387 drugs

Retinoids

Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.

Likelihood Possible Evidence C
Tetracycline Antibiotics

Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.

Arctic Cod Liver Oil Lemon by Nordic Naturals: Common Questions

Does Arctic Cod Liver Oil Lemon by Nordic Naturals interact with any medications?
Yes. Based on its ingredients, Arctic Cod Liver Oil Lemon has a known interaction with 387 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Arctic Cod Liver Oil Lemon contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this safe if I'm pregnant?
The data shows vitamin A at normal supplement amounts is likely safe in pregnancy, but high-dose vitamin A (especially as retinol) is possibly unsafe and can cause birth defects. Talk with your doctor or pharmacist about the dose in this product and what's right for you.
Can I take this with my blood thinner?
High-dose vitamin A theoretically increases bleeding risk with warfarin and other blood thinners. This product contains vitamin A, so check the exact dose and your medications with your doctor or pharmacist before combining them.
What are omega-3 fatty acids for?
The two main omega-3s in cod liver oil — eicosapentaenoic acid and docosahexaenoic acid — are components of fish oil, but we don't have established effectiveness evidence for them in our data.
What happens if I take too much of this?
Vitamin A builds up in your body, so chronic high doses can cause skin problems (dryness, peeling, rash), hair loss, brittle nails, fatigue, and in rare cases liver damage or serious neurological effects. Stick to recommended amounts.
I'm on an antibiotic — is this okay?
If you're taking a tetracycline antibiotic (like doxycycline), this product's vitamin A could theoretically increase the risk of a rare condition called pseudotumor cerebri. Check with your doctor or pharmacist before combining them.
