Which vitamins are most highly recommended for alzheimer's patients?

Probably nothing.: I have read a few claims here and there that vitamin d or vitamin e can help in alzheimer's, but they never seem to hold up in the long run. My best opinion is, unfortunately, that vitamins will not help.

Not clearcut: There is a medical food called cerefolin which contains biologically active folate and b-12, plus n-acetyl-cysteine, and is approved for mild cognitve impairment. A dutch study suggested that a mix of vitamin c and vitamin e might help, but that was not conclusive. Doubt any of these approaches could be harmful, but not fully clear if worth the time and money.
