HelloPharmacist Scorecard of Megabiotin 7,500 mcg by Cardiovascular Research
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 is a single-ingredient supplement: biotin (also called vitamin B7), a B vitamin your body needs to convert food into energy and support healthy hair, skin, and nails. At 7,500 mcg per capsule, this is a high-dose form—much more than you'd get from food alone.
The capsule also contains inactive ingredients (cellulose powder, gelatin, calcium stearate, and silicon dioxide) that help hold the biotin together and keep it shelf-stable.
Does it work?
Strong evidence
Biotin is likely effective for biotin deficiency—if your doctor has confirmed you're low, this dose can help restore normal levels. For other uses listed here—multiple sclerosis, seborrheic dermatitis (flaky, inflamed scalp), and hair loss (alopecia areata)—the evidence is either insufficient to say whether it works, or the available studies suggest it probably doesn't.
How safe is it?
Well-documented data
Biotin is generally well tolerated because your body clears excess amounts through your urine, so high doses don't tend to build up. High-dose biotin has rarely been linked to mild diarrhea; one older trial reported this in a small number of participants taking 300 mg daily.
One isolated case report described a serious inflammatory reaction in a patient taking biotin alongside other supplements and a heart medication, but it's unclear whether biotin was the cause. The product label advises checking with your doctor before taking high-dose biotin supplements, especially if you're pregnant or nursing, though biotin in food and prenatal vitamins is considered likely safe.
Meds to double-check
No known interactions
No interactions are documented in our data for biotin with any medications. Still, check your exact drugs on this page or with your pharmacist before starting—they know your full medication list and can spot anything we might have missed.
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.
Megabiotin is a reasonable choice if your doctor suspects or has confirmed you're biotin-deficient and you want a straightforward, high-dose supplement. If you're taking it for hair, skin, or a neurological condition, talk with your doctor first about whether the evidence supports it for your situation.
Either way, run it past your own healthcare provider before you start, especially if you're pregnant, nursing, or already on other supplements.
