HelloPharmacist Scorecard of Shark Liver Oil Vitamin A by NOW

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: shark liver oil and vitamin A. Shark liver oil is derived from shark liver tissue and has been studied for various health claims, though evidence is limited.

Vitamin A is a fat-soluble vitamin essential for vision, immune function, and skin health. The softgel capsule itself is an inactive ingredient that holds these actives 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: Nutritional support with vitamin A.
  • We looked for evidence on: Vitamin A deficiency, Night vision, Acne, Aging skin, Wrinkled skin, Wound healing — 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, Measles, Night vision, Wrinkled skin.
  • Also on file: Shark Liver Oil is rated "Insufficient Reliable Evidence To Rate" for Common cold, Influenza.

The evidence base differs between the two ingredients here. Vitamin A is effective for vitamin A deficiency and possibly effective for oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia.

For shark liver oil, the data we hold shows insufficient reliable evidence to rate its effectiveness for cancer, chemotherapy-induced low white blood cells, common cold, influenza, and radiation-induced nausea and vomiting. If you're considering this product for a specific condition, talk with your doctor or pharmacist about whether the evidence supports its use.

The evidence, ingredient by ingredient Shark Liver Oil 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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 high doses build up in your body and can become toxic — causing liver damage, headache, vision problems, and skin issues. At very high doses it can be serious.

Shark Liver Oil is generally tolerated short-term, though human safety data are limited and product quality varies. One reported case linked it to severe liver inflammation.

At high doses, shark liver oil raised cholesterol levels in one study; these changes reversed when it was stopped. Rarely, both ingredients have been associated with aspiration and lipoid pneumonia.

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

Why this rating?
  • 1 of the 2 matched ingredients 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 taking this product, double-check with your doctor or pharmacist if you take retinoids or vitamin A derivatives (for acne or aging skin) — Major risk of toxic vitamin A buildup. At Moderate severity: warfarin or other blood thinners, tetracycline antibiotics like doxycycline, or any drugs that can damage your liver.

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 combines two ingredients with limited to modest evidence. Vitamin A works for deficiency and may help a few other conditions; shark liver oil lacks strong evidence for most claims studied.

If you're already taking retinoid acne or skin medications, blood thinners, tetracycline antibiotics, or drugs that stress your liver, you'll need to clear this with your doctor or pharmacist first — the vitamin A content creates real risks. At recommended doses, vitamin A is generally safe, but high doses become toxic over time.

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.

Shark Liver Oil Vitamin A by NOW: Common Questions

Does Shark Liver Oil Vitamin A by NOW interact with any medications?
Yes. Based on its ingredients, Shark Liver Oil Vitamin A 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?
Shark Liver Oil Vitamin A contains 2 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.
Can I take this if I'm pregnant or breastfeeding?
The vitamin A in this product carries conflicting data — it's rated both Likely Safe and Possibly Unsafe in pregnancy and lactation. High-dose vitamin A, especially as retinol, can cause birth defects. Since there's uncertainty, talk with your doctor or pharmacist about whether this product is right for you. For shark liver oil, there isn't enough safety data to know either way — ask your healthcare provider for personalized advice.
What are the side effects I should watch for?
Vitamin A at high doses can cause fatigue, dry skin, skin rashes, hair loss, headache, and blurred vision. Very high doses can damage your liver and raise pressure in your skull. Shark Liver Oil can cause stomach upset and has rarely been linked to severe liver inflammation. Both ingredients have been associated with aspiration and a type of lung inflammation if inhaled.
Does shark liver oil actually work for colds or the flu?
The evidence we have is insufficient to rate shark liver oil for those uses. It's been studied for them, but the data aren't reliable enough to say whether it helps. Talk with your doctor if you're considering it for cold or flu prevention or treatment.
Does this product have any fillers?
The only inactive ingredient listed is the softgel capsule itself, which is the capsule material holding the active ingredients together.
Why does shark liver oil affect cholesterol?
One study showed that high doses of shark liver oil (15 grams daily) raised total cholesterol by about 41.5 mg/dL and lowered HDL cholesterol in healthy adults. Lower doses (1.5 grams daily) didn't significantly change cholesterol levels. The effect reversed after people stopped taking it, so the changes weren't permanent.
Is this safe to take long-term?
Shark Liver Oil is noted as generally tolerated short-term, but human safety data are limited and product quality varies — so long-term safety isn't well established. Vitamin A is safe at recommended amounts but toxic at high doses because it accumulates in your body. Talk with your doctor or pharmacist about how long you plan to take this and whether it's appropriate for you.
