In general, research from many studies has shown that Alzheimer’s disease and dementia is more common in people who have low levels of vitamin D in their body. However, there haven’t been many good quality experiments that would be able to show clearly whether low vitamin D levels cause Alzheimer’s disease. More research is needed to give a clearer answer about whether taking a vitamin D supplement can help prevent or treat Alzheimer’s disease.
Alzheimer’s disease (AD) is a condition that causes memory problems and changes in behavior. Usually, it’s progressive, which means it develops slowly and gets worse over time.
