HelloPharmacist Scorecard of Biotin 300 mcg by Vitamin World

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 contains one active ingredient: biotin, a B vitamin your body uses to break down nutrients and support hair, skin, and nail health. At 300 mcg per tablet, it's a modest dose—well below the high-dose supplements sometimes used in research.

The tablet also contains several inactive ingredients (fillers and binders): dicalcium phosphate, vegetable cellulose, stearic acid, croscarmellose, silica, and vegetable magnesium stearate. These help hold the tablet together and are commonly used across supplement brands.

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: supports healthy hair, skin and nails.
  • We looked for evidence on: Biotin deficiency, Brittle nails, hair loss, nail health, skin condition.
  • The strongest evidence on file: Biotin is rated "Likely Effective" for Biotin deficiency (Natural Medicines).
  • Also on file: Biotin is rated "Insufficient Reliable Evidence To Rate" for Brittle nails.

Biotin is likely effective for treating biotin deficiency—a rare condition where your body doesn't have enough of this B vitamin. For other uses, the evidence is weaker.

It's rated possibly ineffective for multiple sclerosis and seborrheic dermatitis (a flaky, itchy scalp condition), and there isn't enough reliable evidence to rate it for hair loss (alopecia areata).

The evidence, ingredient by ingredient Biotin

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.

Biotin is generally well tolerated, even at fairly high doses, because your body gets rid of excess amounts through urine. At the dose in this product (300 mcg), no safety concerns are on file.

High-dose biotin supplements have rarely been linked to mild diarrhea; in one older case report, a woman taking 10 mg daily developed an unusual chest inflammation, though whether biotin caused it remains unclear and no similar cases have been reported since. During pregnancy and lactation, normal dietary and supplement amounts of biotin are likely safe.

If you're pregnant, breastfeeding, or planning to take a high-dose biotin product, check with your doctor or pharmacist first.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. No medication interactions are currently documented, and safety information is well characterized.

This is a straightforward, low-dose biotin tablet—good if you want to cover a potential biotin deficiency or support general hair and nail health. It has no known drug interactions.

Biotin 300 mcg by Vitamin World: Common Questions

Does Biotin 300 mcg by Vitamin World interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Biotin 300 mcg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Biotin 300 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.
Will biotin help my hair grow or stop it from falling out?
We don't have enough reliable evidence to say whether biotin works for hair loss. If that's your main reason for taking it, talk to your doctor or dermatologist—they can advise based on your individual situation.
Is this dose safe to take every day?
Yes. At 300 mcg, this is a modest dose, and biotin is generally well tolerated even at much higher levels because excess is excreted in urine. No safety concerns are documented at this dose.
Can I take this while pregnant or breastfeeding?
Normal dietary and supplement amounts of biotin are likely safe during pregnancy and lactation. Since this is 300 mcg (a reasonable dose), it should be fine—but check with your doctor or pharmacist to confirm it's right for you.
What's biotin actually for?
Biotin is a B vitamin that helps your body process fats, carbohydrates, and proteins. It's involved in hair, skin, and nail health, and it's necessary to prevent biotin deficiency—though that's rare in people eating a normal diet.
Will this interfere with my blood pressure or diabetes medication?
No interactions are documented between biotin and those or other medication types. Still, if you take any prescription drugs, ask your pharmacist to double-check your specific medications, or use the interaction tool on this page.
