HelloPharmacist Scorecard of Vitamin A 10,000 IU by Woodstock Vitamins

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 Jul 11, 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 contains one active ingredient: vitamin A at 10,000 IU per softgel. The capsule itself is made from inactive ingredients including soybean oil, glycerin, and purified water — standard materials to deliver the vitamin in liquid form.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Support healthy eyes, skin and immune system.
  • We looked for evidence on: Acne, Aging skin, Atopic dermatitis (eczema), Cataracts, Child development, Corneal abrasion — and 4 related terms.
  • The strongest evidence on file: Vitamin A is rated "Possibly Effective" for Aging skin (Natural Medicines).
  • Also on file: Vitamin A is rated "Possibly Effective" for Night vision, Oral leukoplakia.
  • Also on file: Vitamin A is rated "Possibly Ineffective" for Melanoma.

Vitamin A is effective for preventing and treating vitamin A deficiency. The data also shows it's possibly effective for oral leukoplakia (a mouth condition), aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia (a lung condition in premature infants), though the evidence for these uses is less established.

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's fat-soluble, meaning your body stores it — so it can build up over time if you take too much. At very high doses, it can cause liver damage, headaches, skin problems, hair loss, and in rare severe cases, pseudotumor cerebri or even more serious effects.

For pregnancy and breastfeeding, the data shows conflicting ratings: recommended amounts are needed and appropriate, but high doses — especially the retinol form — can cause birth defects. Talk with your doctor or pharmacist about whether this dose is right for you if you're pregnant, planning pregnancy, or breastfeeding.

Side effects, ingredient by ingredient Vitamin A

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

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 taking this, double-check if you're on retinoids (like tretinoin or isotretinoin), warfarin or other blood thinners, tetracycline antibiotics, or any medication that stresses your liver. These have documented moderate-to-major interactions with vitamin A.

The bottom line

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

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.

Vitamin A 10,000 IU by Woodstock Vitamins: Common Questions

Does Vitamin A 10,000 IU by Woodstock Vitamins interact with any medications?
Yes. Based on its ingredients, Vitamin A 10,000 IU 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?
Vitamin A 10,000 IU 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 10,000 IU a safe dose?
Yes — 10,000 IU is the tolerable upper limit set for daily vitamin A intake in adults, so it's designed not to cause harm with everyday use. That said, if you're also taking retinoid medications or certain other drugs, the combination may not be safe, so check with your pharmacist.
Can I take this if I'm pregnant?
The data we have shows both that normal amounts are needed in pregnancy and that high doses — especially as retinol — can cause birth defects. Since this product is at the upper safe limit, talk with your doctor or pharmacist about whether it's right for your situation.
What does vitamin A do?
Vitamin A supports vision, skin health, and immune function. It's proven effective for treating vitamin A deficiency and is possibly effective for certain skin conditions, mouth conditions, and measles — though more research is needed for those uses.
What are the side effects?
At recommended doses, vitamin A is generally well tolerated. At much higher doses, it can cause dry or peeling skin, hair loss, headaches, and in rare cases, serious liver damage or a dangerous increase in brain pressure. This 10,000 IU dose is at the safe daily upper limit.
Can vitamin A build up in my body?
Yes — vitamin A is fat-soluble, so your body stores it instead of flushing it out like water-soluble vitamins. That's why taking too much over time can be toxic, and why it's important not to exceed the upper intake level without medical direction.
