Overview

Natrol Biotin 10,000mcg provides a high-potency dose of biotin (vitamin B7) per tablet. Biotin is the most popular supplement for hair, skin, and nail support, and Natrol is the #1 biotin brand in the US. The 10,000mcg dose is significantly higher than the 30mcg Adequate Intake, but biotin is water-soluble and generally well-tolerated at high doses.

Our Verdict

7.0/10 — Good

Natrol Biotin is the market leader for a reason — affordable, high-potency, and 85,000+ positive reviews. However, most people get adequate biotin from food, and the 10,000mcg dose is far beyond what's needed. More importantly, high-dose biotin can interfere with lab tests (including thyroid and troponin) — stop taking it 72 hours before any blood work.
