Increased Vitamin D Intake May Help Prevent Dementia, Study Shows

Research indicates that one essential vitamin could make all the difference in cognitive decline and brain longevity: vitamin D. According to an observational study published in Alzheimer's & Dementia, older adults who 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.
