Vitamin D is an essential vitamin required by the body for the absorption of calcium, bone development, immune functioning and alleviation of inflammation. Vitamin D comes from the sun and from some foods like nuts, lentils and fatty fish. Researchers have found that low levels of vitamin D could be related to dementia and Alzheimer's disease, one of the most common forms of dementia. Alzheimer's disease can be exhausting for caregivers and frightening to those who have it. People with Alzheimer's disease said "The worst thing that I found was I was getting lost in the car, not just forgetting where I was going, I wouldn't know where I was.”
