HelloPharmacist Scorecard of Biotin 300 mcg by Wonder Laboratories

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 that your body needs to break down fats, carbohydrates, and amino acids. Each tablet or pill delivers 300 mcg.

The inactive ingredients are calcium phosphate, vegetable cellulose, vegetable stearic acid, silica, and vegetable magnesium stearate—these are fillers and binders that help form the tablet.

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: B-vitamin essential nutrient for metabolism.
  • We looked for evidence on: Biotin deficiency.
  • The strongest evidence on file: Biotin is rated "Likely Effective" for Biotin deficiency (Natural Medicines).

Biotin is likely effective for treating biotin deficiency, which is rare but can happen in people with certain genetic conditions or on long-term anticonvulsant medications. For other uses—multiple sclerosis, seborrheic dermatitis (a scaly skin condition), and hair loss (alopecia areata)—the evidence is either insufficient or suggests it probably doesn't help.

If you're considering biotin for one of those other conditions, talk with your doctor about whether it makes sense for you.

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 excretes excess amounts in your urine. At the dose in this product (300 mcg), you're unlikely to run into trouble.

That said, the safety notes advise checking with your doctor before taking high-dose biotin supplements—amounts from food and standard prenatal vitamins are considered appropriate. In rare cases, very high-dose biotin has been linked to mild diarrhea, and one isolated case report described a serious lung and heart lining inflammation in an older woman taking biotin 10 mg daily alongside other supplements and medications, though causation was unclear.

For pregnancy and lactation, biotin is rated likely safe.

Side effects, ingredient by ingredient Biotin

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented for biotin at this dose. You're in the clear with medications, but always mention any new supplement to your doctor or pharmacist so they can review your full picture.

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.

If you have a biotin deficiency, this product can help correct it. For everyone else, the evidence doesn't support biotin for hair loss, MS, or scalp conditions—but it won't hurt at this dose if you want to try it.

Check with your doctor or pharmacist if you're on high-dose supplements or have questions about whether it fits your health plan.

Biotin 300 mcg by Wonder Laboratories: Common Questions

Does Biotin 300 mcg by Wonder Laboratories 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 this help my hair grow back?
The evidence for biotin in hair loss (alopecia areata) isn't strong enough to rate it effective. Some people take it anyway, but talk with your doctor first if that's your main reason—there may be other options worth trying.
Can I take this if I'm pregnant or breastfeeding?
Yes—biotin is rated likely safe in pregnancy and lactation. Amounts from food and prenatal vitamins are standard. If you're thinking about a high-dose supplement, check with your doctor first.
What's the difference between this and higher-dose biotin products?
This one has 300 mcg per tablet. Biotin supplements can range from a few hundred to thousands of micrograms. Higher doses are where the caution notes kick in, so if you're considering a much higher amount, mention it to your doctor.
Are there any side effects?
At this dose, side effects are uncommon. Very high-dose biotin (in the milligram range) has rarely caused mild diarrhea. One unusual case linked severe inflammation to very high biotin use, but that's exceptionally rare and involved other medications too.
What is biotin actually for?
Biotin is a B vitamin your body uses to process fats, carbohydrates, and amino acids. It's especially important if you have a biotin deficiency, which is rare but serious. Most people get enough from food.
