Thorne Biotin, 8,000 mcg, 60 Capsules

Thorne's Biotin supplement provides a high concentration of 8 mg per capsule, formulated to support healthy metabolism, nerves, nails, hair, and skin. The manufacturer notes it may benefit individuals with digestive conditions affecting nutrient absorption, those needing additional support for glucose metabolism, or people taking antibiotics that disrupt gut biotin synthesis.

This product uses a simple formulation with biotin as the sole active ingredient, avoiding common allergens and unnecessary additives. Thorne emphasizes third-party testing to verify label accuracy and confirm the absence of contaminants like heavy metals or pesticides. It comes in a 60-capsule vegetarian capsule format, with the only other ingredients being calcium laurate, hypromellose, microcrystalline cellulose, and silicon dioxide.
