22 Health Benefits of Vitamin D, According to Science

Alzheimer’s/Dementia

Research results confirm that vitamin D deficiency is associated with a substantially increased risk of all-cause dementia and Alzheimer disease. The brain relies on vitamin D receptors for protection.  Scientists do know that vitamin D receptors work in many ways to protect the brain.  A large French study suggests that maintaining adequate vitamin D levels in older age could contribute to slow down cognitive decline and delay or prevent the onset of dementia, especially Alzheimer’s.  In the Invecchiare in Chianti (InCHIANTI) Italian population-based study, low levels of vitamin D were associated with substantial cognitive decline in the elderly population studied during a 6-year period.
