Hair, skin, and nail support is the main reason people reach for **Biotin**, but the clinical evidence only supports benefits if you're actually deficient. At 1,000 mcg per capsule — right at the minimum of the supplement range (1,000–5,000 mcg) — this gives you a moderate dose, and taking the label's upper suggestion of two daily puts you at 2,000 mcg.

The capsule format makes it easy to adjust your intake based on how you respond. Biotin is water-soluble, so your body excretes what it doesn't need, and side effects at these doses are rare.

The key caveat is that if your biotin levels are already normal, you may not notice a meaningful difference. The research showing hair and nail improvements is largely limited to deficient individuals, so managing your expectations around results is important.
