I think you should reconsider taking a multi-bit--even generic is OK. I am a registered dietitian with a Masters in Clinical Nutrition. Now vitamins are for INSURANCE--and a deficiency fo B-vits can cause neurapathy to be worse. It is difficult to insure that you gent enough servings from the breads and cereals group to insure enough B vits. So, just take a multi vit and you do not have to worry about the individual B vits unless your physician finds a special need for them. Remember thiamin (B1), riboflavin (B2), niacin (B3), folic acid, B6, B12 (and a few more) are all important for proper nerve function. Nancy Stephens
