The study was published in the scientific journal Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, specialized in Alzheimer’s disease and dementia, as stated in the German version of Business Insider.

The study included 12,000 people with an average age of 71 years, and all of them did not show any symptoms of dementia at the beginning of the study.

Ten years following the study began, nearly 2,670 of the study participants had developed dementia. Twenty-five percent of them took vitamin D supplements, while regarding 75 percent did not.

Researchers found that the group of participants who took a vitamin D supplement had 40 fewer strokes than those who did not take it.

Skepticism and previous studies

However, some experts pointed to the limitations of the study and its inability to establish a link between intake Vitamin D supplements and avoiding dementia. Among their concerns regarding the study is that it did not take into account other ways to obtain vitamin D, such as sunlight and light.

In December, a study conducted by a research team from Tufts University, USA, concluded that high levels of vitamin D in the brain help improve human mental functions.
