b-12, the vite mys are related. i didn't find vitamin "d." there are studies from egypt and others and small group that found relationships. i tell the viewers to check vite my "d" to make sure you're not low. that could play a role. >> couple of points about vitoligo. it could be genetic. there is a gene now the nalp1 gene associated with vitiligo. it's when the pigment cells are destroyed in other areas so you have white blotches of skin rate. they treated with the ultraviolet light. that also increases your vitamin "d" level. but i don't find any direct link like david said. there is a link with the vitamin "d" deficiency and autoimmune diseases like lupus and rheumatoid arthritis that can be associated with vitiligo. if you have it and an autoimmune disease they should extra check you for vitamin "d" deficiency.
