Biotin (Vitamin B7) in menopause

Biotin (vitamin B7) is a water-soluble vitamin popular for hair, nails, and skin. For menopausal women with hair loss and brittle nails, biotin 5000-10000mcg daily is the typical dose. Evidence is moderate, and it is most helpful if you are biotin deficient. Halal status is easy to verify; it usually comes in a vegetable capsule.
