Many studies and literature have shown that there are deficiencies of vitamin D in a spectrum of skin disorders, such as lupus, psoriasis, atopic dermatitis, morphea, alopecia acreata and new studies in vitiligo.
So, recent studies have proven that:
Vitiligo patients have higher vitamin D levels compared to other skin diseases. However, there is a group of vitiligo patients who are vitamin D deficient. Those patients also have higher incidents of diabetes and hyperthyroidism.
After studying individuals who had skin type I-III versus IV-VI, we found that incidents with vitamin D deficiencies were less in phototypes I-III versus the darker IV-VI.
Finally, having looked at patients with severe vitiligo we found higher levels of vitamin D versus the patients with moderate or mild vitiligo.
