The Vitamin Shoppe Biotin 10,000 mcg

Our assessment

The evidence shows that this product contains a very high dose of biotin, but the data provided does not include specific information about this ingredient. Based on the data available, the product label lists "See label" for ingredients, and the only ingredient with detailed data is calcium. For biotin specifically, data is not available in the provided materials. For general supplement guidance, calcium is well-supported for bone health, but this product’s high biotin dose would require additional data to evaluate fully.

How it works

If this product contained calcium, it would work through bone mineralization, supporting bone density and mineral deposition, as well as neuromuscular relaxation, aiding muscle relaxation and nerve signaling [NIH ODS]. However, since the product is labeled as biotin, the mechanism of action for biotin is not covered in the provided data. You should consult the product label for specific ingredient details.

Safety profile

Data not available for biotin specifically. For the ingredient calcium, high intakes might increase the risk of heart disease and prostate cancer, and can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA received a total of 592,059 adverse event reports across all supplements, but report counts for this specific product are not provided [FDA data].

Our recommendation

Data not available to make a specific recommendation for this biotin product. For supplements containing calcium, you should be aware that calcium can reduce the absorption of several medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Always check with your pharmacist or doctor before starting a new supplement, especially at high doses like 10,000 mcg.
