Summary
This biotin supplement contains a simple formulation with minimal additives, which is generally positive for ingredient safety. However, the presence of magnesium stearate and silica as fillers, while common, slightly detracts from the overall purity of the product. The use of gelatin capsules may not be suitable for all dietary preferences, but the product remains a reasonable choice for those seeking biotin supplementation.
