Taking vitamin D supplements may help ward off dementia, according to a study led by an international team of researchers. Researchers at the University of Calgary`s Hotchkiss Brain Institute in Canada and the University of Exeter in the UK explored the relationship between vitamin D supplementation and dementia in more than 12,388 participants. Of the group, 37 per cent (4,637) took vitamin D supplements.
The team found that taking vitamin D was associated with living dementia-free for longer, and they also found 40 per cent fewer dementia diagnoses in the group who took supplements. Across the entire sample, 2,696 participants progressed to dementia over ten years; amongst them, 2,017 (75 per cent) had no exposure to vitamin D throughout all visits prior to dementia diagnosis, and 679 (25 per cent) had baseline exposure.
