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.
What’s inside
Full disclosure
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
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).
How safe is it?
Well-documented data
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.
Meds to double-check
No known interactions

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.
If you're pregnant, taking other medications, or considering a much higher dose for a specific condition, talk it over with your doctor or pharmacist to make sure it fits your situation.
