Vitamin D: Is It Ready for Psychiatric Prime Time?

Abstract

atric medicine, Leard-Hansson and Guttmacher concluded that “vitamin D sufficiency may improve mood status in those experiencing seasonal affective disorder-type symptoms, and it may improve cognitive performance in Alzheimer’s disease patients.” They also opined that deficiency of the vitamin in early life may be a risk factor for schizophrenia. The critical word is “may,” indicating a lack of certitude, which, as we shall see, is quite appropriate.
