Overview

Nutricost Biotin provides 10,000mcg (10mg) of biotin per softgel in a 240-count bottle. Biotin (vitamin B7) is a water-soluble B vitamin essential for keratin production — the structural protein in hair, skin, and nails. While biotin deficiency is rare, supplementation at high doses (2,500-10,000mcg) has been shown to improve hair thickness and nail brittleness in those with suboptimal levels. The softgel form includes coconut oil for enhanced absorption of this water-soluble vitamin. At 240 softgels for under $16, this provides an 8-month supply.
