Studies Show That Low Levels Of Vitamin D Put Older Women At Risk For Cognitive Decline

In separate studies, French and American researchers have discovered an association between levels of vitamin D intake and cognitive health in women. In particular, the study found that greater vitamin D intake is associated with a lower risk of developing Alzheimer’s disease. The French findings were based on data collected from 498 women who participated in an osteoporosis study. Women who developed Alzheimer's disease had lower baseline vitamin D intakes (50.3 mg a week) than those who developed other dementias (63.6 mg a week) or no dementia at all (59 mg a week). A related U.S. study found that older women with lower vitamin D levels were more at risk for cognitive impairment and cognitive decline.
