Vitamin deficiencies are common in many countries, with research indicating that individuals are likely to supplement with a daily multivitamin as opposed to individual vitamin supplements. Therefore, there is a need understand the effects of multivitamins on all aspects of human health, including brain function. This review summarizes the evidence as to whether multivitamin supplementation can improve cognitive function in adults. Studies focusing on cognitively intact adults and those with dementia are both discussed. Across studies, there is some evidence to suggest that multivitamins may improve memory recall in cognitively intact adults; however, larger randomized controlled trials with longer supplementation durations are needed to substantiate this finding. There is insufficient evidence to infer the effects of multivitamins on cognitive functioning in those with dementia.
