Here is an interesting vitiligo site I found out about today, http://www.vitsaf.org/
It's the Vitiligo Support and Awareness Foundation, based in Nigeria, and it has some good information and contacts.
Myself, I started taking a B6, B12 and folic acid vitamin daily which is supposed to help increase red blood cells. Even if it doesn't take away the vitiligo, maybe it will help it slow down. I'm also looking to try a product from Australia called Vitiligo Organics.
