If you're hoping for hair, skin, or nail support, this **Biotin** supplement delivers 10,000 mcg per tablet — well above the 1,000–5,000 mcg range commonly found in similar products. However, biotin supplementation has only shown clear benefits in people who are actually deficient. If your levels are normal, the clinical evidence for hair or nail improvement is weak.
The 96 mg of **Calcium** (as carbonate) is minimal and unlikely to contribute meaningfully to your daily intake. It's there as a tablet binder, not a functional dose.
The biggest thing to know before buying: biotin's reputation far outpaces its research. There are no well-designed RCTs proving it grows hair or strengthens nails in healthy, non-deficient adults. If you suspect a deficiency, this dose is more than adequate — but if you're hoping for cosmetic results on its own, the evidence isn't there to support that expectation.
