HelloPharmacist Scorecard of Biotin 1,000 mcg by NOW
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 the proteins, fats, and carbohydrates you eat. The capsule also holds inactive ingredients — rice flour, hypromellose (a plant-based capsule material), ascorbyl palmitate (a form of vitamin C used as a preservative), and silicon dioxide — that help deliver the biotin.
Does it work?
Strong evidence
Biotin is likely effective for treating biotin deficiency, a rare shortage of the vitamin itself. For multiple sclerosis and seborrheic dermatitis (a skin condition causing redness and flaking), the evidence suggests biotin is possibly ineffective.
For hair loss (alopecia areata), there isn't enough reliable evidence yet to rate whether it works. If you're taking this for a specific condition, talk with your doctor about whether biotin is the right choice for you.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body gets rid of excess in your urine. At the dose in this product (1,000 mcg), it's considered safe for most people.
High-dose biotin rarely causes mild diarrhea. One unusual case report linked high-dose biotin (along with other supplements and a heart medication) to a rare chest condition, but it's unclear whether biotin was the cause — no similar cases have been reported since.
If you're thinking of taking high-dose biotin supplements beyond normal dietary amounts, check with your doctor first.
Meds to double-check
No known interactions
No interactions are documented for the ingredient we could check. Run your exact medications through the search tool on this page if you want to be thorough, but there's no known concern with standard medications.
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 product is a straightforward biotin supplement for anyone who wants extra B-vitamin support or has a biotin deficiency. If you're taking it for a specific condition like hair loss or a skin problem, the evidence is weak or mixed — talk with your pharmacist or doctor to see if it's right for you.
No major drug interactions are documented, but mention it to your healthcare team if you take lots of supplements.

Formula
Biotin is a water-soluble vitamin necessary for normal growth and body function. Biotin functions as a key regulatory element in gluconeogenesis, fatty acid synthesis, and in the metabolism of some amino acids. Alongside its role in energy production, biotin enhances the synthesis of certain proteins. In addition, biotin promotes healthy immune system function and plays a critical role in skin health.
