Does vitamin D deficiency cause lichen sclerosus?
There is no proven link between vitamin D deficiency and the development of lichen sclerosus. Some small studies have shown lower vitamin D levels in people with autoimmune skin disorders, but evidence is limited.
Detailed Medical Explanation
Vitamin D is important for immune health and skin barrier function, but lichen sclerosus is a complex condition with genetic and immune causes. While it’s reasonable to maintain healthy vitamin D levels, supplementation has not been shown to prevent or cure lichen sclerosus. For general vitamin D guidance see NHS vitamin D and BAD.
Clinical Context
Our clinic can advise on healthy vitamin D levels and supplementation if required: Vulval Skin Conditions Clinic.
Evidence-Based Approaches
Vitamin D supplements are safe in recommended doses. No current evidence supports their use as a treatment for lichen sclerosus. For more information, see NHS.
