HelloPharmacist Scorecard of Biotin 300 mcg by Solgar
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 uses to break down food and convert it into energy. At 300 micrograms per tablet, this is a moderate supplemental dose.
The tablet also contains several inactive ingredients—dicalcium phosphate, microcrystalline cellulose, stearic acid, vegetable cellulose, vegetable magnesium stearate, and silica—which serve as binders and fillers to hold the tablet together.
Does it work?
Strong evidence
Biotin is likely effective for biotin deficiency, the condition it's most studied for. For multiple sclerosis and seborrheic dermatitis (a flaky, inflamed scalp condition), the evidence suggests it's probably not effective.
For hair loss (alopecia areata), there isn't enough reliable evidence to say whether biotin helps. If you're taking this for a specific condition, talk with your doctor about whether the evidence supports it for your situation.
How safe is it?
Well-documented data
Biotin is generally well tolerated at most doses because your body excretes excess amounts in urine—it doesn't store up. At very high doses, mild diarrhea has occasionally been reported in a small number of people.
One rare case report described a serious inflammatory reaction in a 76-year-old woman taking biotin 10 mg daily along with other supplements and medications, but it's unclear whether biotin was the cause; no other similar cases have been reported. During pregnancy and lactation, dietary amounts and standard prenatal vitamins containing biotin are considered likely safe, but if you're thinking about taking a high-dose supplement, check with your doctor first.
Meds to double-check
No known interactions
No interactions are documented in our data for the biotin in this product. That said, it's always smart to confirm with your own pharmacist or doctor before adding any supplement to your routine, especially if you take multiple 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 straightforward: it's biotin at a standard supplemental dose, and it's generally well tolerated. It works for biotin deficiency but isn't proven to help with other common reasons people take it, like hair loss or skin conditions.
If you're pregnant, breastfeeding, or considering a high-dose supplement, talk it over with your doctor or pharmacist before starting.
