HelloPharmacist Scorecard of Biotin 1,000 mcg by Source Naturals

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 food and convert it to energy. Biotin also supports the health of your hair, skin, and nails.

The tablet also contains inactive ingredients — microcrystalline cellulose (a filler), stearic acid, and magnesium stearate — that help form and hold the tablet 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: Hair and skin support.
  • We looked for evidence on: Brittle nails, Seborrheic dermatitis, Biotin deficiency, Hair loss, Skin quality.
  • The strongest evidence on file: Biotin is rated "Likely Effective" for Biotin deficiency (Natural Medicines).
  • Also on file: Biotin is rated "Possibly Ineffective" for Seborrheic dermatitis.
  • Also on file: Biotin is rated "Insufficient Reliable Evidence To Rate" for Brittle nails.

Biotin is likely effective for biotin deficiency, which can develop from certain medical conditions or medications that interfere with how your body absorbs this vitamin. For other uses — multiple sclerosis, seborrheic dermatitis (a flaky, itchy scalp condition), and hair loss from alopecia areata — the evidence either doesn't support biotin or isn't strong enough to say whether it helps.

If you're considering biotin for a specific health concern, talk it over with your doctor to see whether it's a reasonable choice 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. High-dose biotin has rarely been linked to mild diarrhea; one clinical trial reported transient mild diarrhea in 2 patients taking 300 mg daily.

A single case report from France described a woman who developed eosinophilic pleuropericarditis (inflammation of the heart and lung lining) after taking biotin 10 mg and pantothenic acid daily for 2 months, but it's unclear whether biotin was the cause, and no similar cases have been reported since. Amounts from food and prenatal vitamins are appropriate for most people, but if you're considering high-dose biotin supplements, check with your doctor first.

Biotin 1,000 mcg by Source Naturals: Common Questions

Does Biotin 1,000 mcg by Source Naturals interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Biotin 1,000 mcg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Biotin 1,000 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.
Is biotin safe to take if I'm pregnant or nursing?
Yes, biotin is rated likely safe during pregnancy and lactation. Amounts from food and prenatal vitamins are appropriate. If you're considering a high-dose supplement like this one, check with your doctor first to make sure it's right for your situation.
Will biotin help my hair grow or stop hair loss?
The evidence for biotin in alopecia areata (patchy hair loss) is insufficient — there's not enough reliable data to say whether it helps. If you're losing hair, talk with your doctor to find out what's causing it and whether biotin is a reasonable option for you.
What's biotin actually for?
Biotin is a B vitamin that helps your body break down food and make energy. It also supports healthy hair, skin, and nails. Biotin deficiency is rare but can happen with certain medical conditions, and biotin supplements are likely effective for that.
Can biotin cause side effects?
Biotin is generally very well tolerated. High doses have rarely caused mild diarrhea. One isolated case report linked high-dose biotin to inflammation of the heart and lung lining, but no similar cases have been reported, so this is extremely uncommon.
Does this product have fillers?
Yes — the tablet contains microcrystalline cellulose, stearic acid, and magnesium stearate, which are inactive ingredients that help form and stabilize the tablet. These are standard and generally well tolerated.
