HelloPharmacist Scorecard of High Potency Biotin 1000 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 1000 mcg per tablet. Biotin is a B vitamin your body uses to convert food into energy and support the health of your hair, skin, and nails.
The tablet also includes inactive ingredients (dicalcium phosphate, vegetable cellulose, silica, and stearic acid) that help hold it together.
Does it work?
Strong evidence
Biotin is likely effective for treating biotin deficiency — a real but uncommon shortage of this vitamin in your body. For other uses like hair loss (alopecia areata), seborrheic dermatitis (a scaly skin condition), and multiple sclerosis, the evidence isn't strong enough yet to say whether biotin helps.
If you're taking it for one of those reasons, talk with your doctor about whether it's worth trying.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body gets rid of excess through urine. High-dose biotin has rarely been linked to mild diarrhea in a small number of people taking much larger doses than this product.
One unusual case report described a severe reaction in an older patient taking both biotin and other supplements for 2 months, but that's been the only report of its kind and it's unclear what caused it. Because this is a high-dose supplement, check with your doctor before you start — amounts from food and prenatal vitamins are fine, but high-dose products deserve a quick conversation first.
Biotin is considered likely safe in pregnancy and lactation.
Meds to double-check
No known interactions
No interactions are documented in our data for the biotin in this product. Still, check your exact medications using the search tool on this page, and confirm with your own pharmacist before you start.
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.
If you have a biotin deficiency, this product is likely to help. If you're taking it for hair, skin, or a neurological condition, the evidence is weaker — worth discussing with your doctor.
Because it's a high-dose supplement, run it by your doctor or pharmacist before you start, especially if you take other medications or have any health conditions.
