biotin

Keratin synthesis aid

Biotin is a B vitamin essential for metabolizing fats, carbohydrates, and proteins.

Also called vitamin B7 or vitamin H, it's found in eggs, nuts, and organ meats.

Biotin supplements are marketed for strengthening hair and nails, though evidence for this benefit in people without deficiency is limited: She started taking biotin for her brittle nails.
