Upping Vitamin D Intake Can Help Prevent Dementia, New Study Says

New research indicates that one essential vitamin could make all the difference in cognitive decline and brain longevity: Vitamin D.

According to a new observational study published in Alzheimer’s & Dementia this week, older adults that increased their vitamin D intake were 40% less likely to develop dementia. The study also learned quite a bit about how individual factors (e.g., demographics, genetics, behavior) play into the equation.
