How True Is The New Study That Claims Vitamin D Supplements Reduce the Risk of Alzheimer's Disease By 40%?

The connection between Alzheimer's disease (AD) and vitamin D status has been known for some time. A 2015 review of the literature concluded that being deficient in vitamin D presented a 21% greater chance of developing Alzheimer's compared to those with adequate levels of vitamin D above 50 nmol/L. Researchers at the University of Calgary's Hotchkiss Brain Institute in Canada and the University of Exeter in England explored the relationship between vitamin D supplementation and dementia in more than 12,388 subjects. They found that subjects who had a history of vitamin D supplementation were 40% less likely to develop Alzheimer’s disease. The results are exaggerated due to normal statistical trickery, but there is still a strong correlation. I will break the study down and explain the real results. I will also give my two cents on whether you should supplement.
