Overview

Natrol Biotin 10,000mcg is the bestselling biotin supplement with 82,400+ reviews. Biotin (vitamin B7) is essential for keratin production — the protein that makes up hair, skin, and nails. The 10,000mcg dose is 33,333% of the daily value, designed for those wanting maximum biotin support for hair growth and nail strength. Biotin is water-soluble, so excess is excreted. The 100-tablet count at $0.08-0.12 per tablet makes it one of the most affordable supplements available.
