"The #1 selling biotin supplement — 250 softgels for under $14"
Overview
Nature's Bounty Biotin 10,000 mcg delivers a high-potency dose of biotin (vitamin B7) in a rapid-release softgel. Biotin is essential for keratin production — the protein that makes up hair, skin, and nails. While biotin deficiency is rare, supplementation at 2,500-10,000 mcg has been shown to improve hair thickness and nail strength in those with suboptimal levels. With 85,000+ Amazon reviews, this is the most popular biotin supplement in America.
