HelloPharmacist Scorecard of Biotin 900 mcg by Sundown 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.
What’s inside
Full disclosure
This product contains one active ingredient: biotin at 900 micrograms per tablet. Biotin is a water-soluble B vitamin your body uses to help convert food into energy and support healthy skin, hair, and nails.
The tablet also contains inactive ingredients — calcium carbonate, vegetable cellulose, silica, and vegetable magnesium stearate — which are fillers and binders that hold the tablet together.
Does it work?
Strong evidence
Biotin is likely effective for treating biotin deficiency, which is rare but can happen. For multiple sclerosis and seborrheic dermatitis (a skin condition), the evidence suggests biotin is probably not effective.
For hair loss (alopecia areata), there isn't enough reliable evidence to know whether it works.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at higher doses, because your body flushes out excess in your urine. At the dose in this product (900 mcg), you're unlikely to run into problems.
High-dose biotin supplements — much larger than what's here — have rarely caused mild diarrhea, and one isolated case report linked very high doses to a chest inflammation, though that involved other medications too and hasn't been repeated. Amounts from food and regular supplements are considered likely safe in pregnancy and while breastfeeding, but if you're thinking about taking a high-dose biotin product, talk with your doctor first.
Meds to double-check
No known interactions
No interactions are documented for biotin in our data. That said, use the search tool on this page to check your exact medications before you start — absence of documented interactions isn't a guarantee none could occur.
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.
This is a straightforward biotin supplement for anyone deficient in the vitamin or looking to support hair, skin, and nail health on a budget. If you're pregnant, breastfeeding, or take multiple medications, a quick conversation with your doctor or pharmacist will make sure this fits your routine.
The dose here is modest and well tolerated in most people.
