HelloPharmacist Scorecard of Biotin 300 mcg by DC
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 that your body needs to process fats, carbohydrates, and amino acids. Biotin 300 mcg is a single-ingredient supplement.
The tablet also contains inactive ingredients — calcium phosphate, vegetable cellulose, vegetable stearic acid, silica, and vegetable magnesium stearate — which are fillers and binders that give the tablet its form.
Does it work?
Strong evidence
Biotin is likely effective for treating biotin deficiency, which can occur in certain medical conditions or with some medications. For other uses — multiple sclerosis, seborrheic dermatitis (a scaly skin condition), and hair loss (alopecia areata) — the evidence isn't strong enough to say it works.
Alopecia areata, in particular, doesn't have reliable evidence one way or the other.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body eliminates excess amounts in urine. At very high doses — much higher than this 300 mcg tablet — mild diarrhea has been rarely reported.
One isolated case report described a woman who developed inflammation in the lining of her heart and lungs after taking high-dose biotin along with another supplement and a heart medication, but it's unclear whether biotin was the culprit, and no similar cases have been reported since. Normal dietary amounts and standard supplement doses are considered safe.
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.
Biotin 300 mcg makes sense if you have a biotin deficiency or your doctor recommends it for that reason. If you're taking this at a high dose (this product isn't high-dose), check with your doctor first, since the safety data advises confirming higher amounts with them beforehand.
No interactions are documented with medications, but run it by your own pharmacist if you're on prescription drugs or want extra reassurance.
