HelloPharmacist Scorecard of Biotin 300 mcg by Puritan's Pride Premium

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 water-soluble B vitamin. Your body uses biotin to help convert food into energy and to support healthy hair, skin, and nails.

At 300 mcg per tablet, this is a modest dose — well above the daily adequate intake but far below the high-dose amounts used in some research studies. The tablet also contains inactive ingredients (dicalcium phosphate, vegetable cellulose, and stearic acid) that help hold it 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

This product doesn't appear to be marketed for a specific use, so we graded Biotin's overall clinical evidence instead.

Strong

Strong clinical evidence supports Biotin for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Biotin deficiency — rated "Likely Effective" (Natural Medicines).

Biotin is likely effective for treating biotin deficiency — a rare condition that causes hair loss, skin rashes, and neurological problems. For other uses, the picture is less clear.

The evidence suggests biotin may not help with multiple sclerosis or seborrheic dermatitis (a scaly skin condition). For hair loss due to alopecia areata, there isn't enough reliable evidence to say whether it works.

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 high doses, because your body flushes the excess out in your urine. At this dose (300 mcg), you're unlikely to run into trouble.

That said, the safety data does offer one caution: if you're thinking about taking high-dose biotin supplements, check with your doctor first — especially if you're pregnant or breastfeeding. Normal dietary amounts and amounts in prenatal vitamins are considered safe.

Mild diarrhea has been reported rarely in people taking much larger doses (300 mg daily — a thousand times this dose).

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 in our data.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.

If you have biotin deficiency, this product can help. If you're taking it for hair, skin, or nail health without a deficiency, the evidence doesn't strongly support that use — but it's unlikely to harm you either.

Talk with your doctor or pharmacist about whether this dose makes sense for your situation.

Biotin 300 mcg by Puritan's Pride Premium: Common Questions

Does Biotin 300 mcg by Puritan's Pride Premium 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?
The evidence for biotin and hair growth in people without a biotin deficiency isn't strong. It's likely effective only if you actually have a biotin deficiency, which is rare. If you're concerned about hair loss, talk with your doctor to find out what's really going on.
Is biotin safe to take every day?
Yes — biotin is generally well tolerated at this dose. Your body gets rid of excess biotin through urine, so it doesn't build up. Just avoid very high-dose supplements without talking to your doctor first.
Can I take biotin while pregnant or breastfeeding?
Biotin is rated likely safe during pregnancy and lactation. Normal dietary amounts and prenatal vitamins are fine — but if you're thinking about taking a high-dose supplement, check with your doctor to make sure it's right for you and your baby.
What is biotin, exactly?
Biotin is a B vitamin your body uses to turn food into energy and to support healthy hair, skin, and nails. Most people get enough from food, but some people take supplements if they have a deficiency.
Are there any side effects?
At this dose, side effects are very unlikely. Mild diarrhea has been reported, but only in people taking doses a thousand times higher than this one.
