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 US National Alzheimer’s Coordinating Center, who had a mean age of 71 and were dementia-free when they signed up. Of the group, 37 per cent (4,637) took vitamin D supplements.
In the study, published in Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 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.University of Exeter. “Taking vitamin D could help prevent dementia: Taking vitamin D supplements may help ward off dementia, according to a new, large-scale study..” ScienceDaily. http://www.sciencedaily.com/releases/2023/03/230301101511.htm (accessed March 1, 2023) — https://www.sciencedaily.com/releases/2023/03/230301101511.htm
