Does vitamin D darken skin?
Dr. Kaufman concluded that darker skin pigmentation is associated with lower serum 25-hydroxyvitamin D concentration. Serum vitamin D level also appears to be related to intake of vitamin D – rich foods and multivitamins containing vitamin D, but not self-reported level of sun exposure or use of sun protection.
