Dr. Joel Wallach says treatment for vitiligo is extracts of placenta, live cell therapy, PABA at 100 mg q.i.d., phenylalanine at 50 mg/kg/day, copper at 2mg per day, vitamin A at 300,000 IU per day as beta carotene, zinc at 50 mg t.i.d., Vitamin B12 at 2000 mcgs per day, folic acid 1mg per day and a nutritional supplementation program that includes plant derived colloidal minerals.

I hope that helps,
