Spring Valley Biotin 10,000mcg

"Walmart's house brand high-dose biotin — the most affordable biotin supplement with 40,000+ reviews"
Overview
Spring Valley Biotin 10,000mcg is Walmart's house brand biotin supplement and one of the most affordable on the market. At 120 softgels for under $10, it provides a 4-month supply of high-dose biotin for hair, skin, and nail support. Biotin (vitamin B7) is a water-soluble B vitamin that serves as a cofactor for enzymes involved in keratin production. While biotin deficiency causes hair loss and brittle nails, the evidence for supraphysiological doses (like 10,000mcg) improving hair growth in non-deficient individuals is limited. Nevertheless, it remains one of the best-selling beauty supplements.
