HelloPharmacist Scorecard of Biotin 1000 mcg by Sundown
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. The tablet also includes inactive ingredients (calcium carbonate, vegetable cellulose, silica, and vegetable magnesium stearate) that serve as fillers and binders.
Does it work?
Strong evidence
Biotin is likely effective for treating biotin deficiency — a rare condition in which your body doesn't get enough of this vitamin. For other uses, the evidence we hold is weaker.
It's rated possibly ineffective for multiple sclerosis and seborrheic dermatitis (a skin condition), and there isn't enough reliable evidence to rate it for alopecia areata (patchy hair loss).
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body discards excess through urine. The most common side effect reported with very high doses (much higher than this 1000 mcg tablet) has been mild diarrhea in a small number of people.
One rare case report linked high-dose biotin to a serious chest inflammation, but that involved a patient taking multiple supplements and other medications, and no similar cases have been reported since — a single isolated case doesn't establish a pattern. For pregnancy and breastfeeding, amounts from food and prenatal vitamins are considered likely safe, but if you're taking or considering high-dose biotin supplements, talk with your doctor first.
Meds to double-check
No known interactions
No interactions are documented for biotin in our data. You can use this product with your medications without worry from a drug-interaction standpoint.
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 B vitamin supplement useful if you have biotin deficiency. It doesn't interact with medications.
If you're pregnant, breastfeeding, or taking high-dose biotin for a specific condition (like hair loss or skin health), run it by your own doctor or pharmacist to make sure it fits your individual situation.
