A new study suggests a link between sufficient vitamin D levels and a reduced risk of developing Alzheimer's disease. Researchers followed a large group of adults for 14 years, analyzing their vitamin D status, supplements, and dementia diagnoses. The findings indicate a potential 17% reduction in Alzheimer's risk for those with adequate vitamin D.
Research Shows Vitamin D May Lower Your Risk Of Alzheimer’s By 17% While vitamin D is most known for its role in bone health, there are vitamin D receptors throughout the body—including the brain. And there’s no shortage of research showing that vitamin D plays a role in memory and even mood.But scientists are now trying to hone in on just how much vitamin D status influences the risk of cognitive conditions like Alzheimer’s disease.
In this study, researchers followed a large group of people over 14 years to see how their vitamin D status, vitamin D supplementation, and multivitamin use influenced the onset of an Alzheimer’s disease of vascular dementia diagnosis. Here’s what you need to know. About the study Studying the incidence of an Alzheimer’s diagnosis is no easy feat. There are a lot of factors to consider, and researchers of this study did their due diligence. They were able to gather data on almost 270,000 adults (ages 55 to 69 at the start of the study) including their use of supplements (vitamin D or multis), blood levels of vitamin D, and dementia status around 14 years later. At the start of the study: Researchers also accounted for other factors that influence dementia risk including demographic characteristics, socioeconomic status, lifestyle habits, and genetic factors including the APOE4 genetic variation.By considering these factors, they could more accurately isolate the vitamin D and dementia relationship. The link between vitamin D and dementiaAt the end of the study, researchers found: One interesting finding the researchers noted was that they did not find a link between vitamin D levels and dementia among study participants with darker skin tones.This finding should be taken cautiously though, as it’s based on a much smaller sample size (the U.K. Biobank cohort is not very racially diverse and consists of predominantly white participants
