HelloPharmacist Scorecard of Biotin 5000 mcg by Rexall
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 convert food into energy and maintain healthy hair, skin, and nails. The capsule also includes inactive ingredients—calcium carbonate, gelatin, silica, and vegetable magnesium stearate—which are fillers and binders that hold the supplement together.
Does it work?
Not established
Biotin is likely effective for biotin deficiency, the clearest use for this supplement. For other conditions—multiple sclerosis, seborrheic dermatitis (a scaly skin condition), and alopecia areata (patchy hair loss)—the evidence in our data is either insufficient to rate or suggests it may not be effective.
Talk with your doctor about whether biotin makes sense for your particular situation.
How safe is it?
Well-documented data
Biotin is generally well tolerated, even at fairly high doses, because your body removes excess amounts through urine. High-dose biotin has rarely been linked to mild diarrhea in trial participants.
One isolated case report described an unusual inflammatory condition in a patient taking biotin alongside other supplements and medications, though it's unclear whether biotin was the cause. The safety data supports normal dietary and supplement amounts, but the manufacturer advises checking with your doctor before taking high-dose products like this one.
Meds to double-check
No known interactions
No interactions are documented in our data for the biotin in this product. Still, run your exact medications through the checker on this page, or ask your doctor or pharmacist to confirm there are no concerns before you start.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.
Rexall Biotin 5000 mcg is most useful if you have a biotin deficiency—something your doctor can test for. If you're considering it for hair, skin, or nail health without a known deficiency, the evidence is limited.
High-dose biotin is generally safe, but it's smart to confirm with your doctor or pharmacist before you start, especially if you're pregnant, breastfeeding, or have any health concerns.
