Two recent studies seem to suggest that higher intake of Vitamin D can be protective for women's mental health and can offset some of the risks of Alzheimer's. The research group found that reduced vitamin D levels among older women is connected to the risk of cognitive impairment and cognitive decline. The research team conducted their study on 498 community-dwelling women. The study revealed that women who developed Alzheimer's disease were those who had lower baseline Vitamin D intakes than those who developed other dementia's or no dementia at all. Earlier research had indicated that both men and women who do not get adequate Vitamin D may run a high risk of suffering disabilities.
