HelloPharmacist Scorecard of d-Biotin 1000 mcg by Kirkman
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 (also called vitamin B7), at a dose of 1000 micrograms per capsule. Biotin is a B vitamin that your body uses to help convert food into energy and to support the health of your hair, skin, and nails.
The capsule itself is filled with microcrystalline cellulose (a plant-based filler) and enclosed in a vegetarian capsule.
Does it work?
Strong evidence
Biotin is likely effective for biotin deficiency — the condition that develops when you're not getting enough of this B vitamin from food or absorption. For other uses like multiple sclerosis, seborrheic dermatitis (a flaky skin condition), and hair loss (alopecia areata), the evidence in our data either suggests it probably doesn't work or is too thin to draw a conclusion.
If you're taking this for a specific condition beyond straightforward biotin deficiency, it's worth asking your pharmacist what the research actually shows for your situation.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body excretes excess amounts in your urine. High-dose biotin has rarely been linked to mild diarrhea — one trial reported transient mild diarrhea in 2 patients taking 300 mg daily (this product is 1 mg).
There is one isolated case report of a woman who developed a heart and lung inflammation after taking 10 mg biotin along with other supplements and a heart medication, but whether biotin caused it remains unclear, and no similar cases have been reported since. The safety data advises checking with your doctor before taking high-dose biotin supplements, even though it's considered safe at normal dietary and supplement levels.
Meds to double-check
No known interactions
No interactions are documented in our data for the biotin in this product.
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 biotin supplement useful if you have a biotin deficiency. It's not a heavy hitter for other conditions like hair loss or skin problems — the evidence for those is weak or negative.
No medication interactions are documented. If you take medications regularly or are pregnant or breastfeeding, a quick chat with your pharmacist can confirm it fits your situation.
