Serum Vitamin B12, Folate, Ferritin, and Iron Levels in Turkish Patients with Alopecia Areata

The study investigated serum levels of vitamin B12, folate, ferritin, and iron in Turkish patients with alopecia areata. The researchers aimed to determine if deficiencies in these nutrients were associated with the condition. The findings suggested that there were no significant differences in the levels of these nutrients between patients with alopecia areata and healthy controls, indicating that deficiencies in vitamin B12, folate, ferritin, and iron might not be directly linked to the development of alopecia areata.
