This common vitamin was linked to 13% better cognitive scores
A study from Emory University indicates that high daily doses of vitamin D are associated with better cognitive performance in adults with mild cognitive impairment. The findings suggest a potential window for intervention to support brain health before dementia progresses.
Why it matters
As Alzheimer's cases rise, identifying accessible, low-cost interventions like vitamin supplementation could be critical for public health.
More than 7 million Americans are currently living with Alzheimer's dementia, and that number is expected to climb to nearly 13 million by 2050. New research from Emory University suggests that higher vitamin D supplement intake may be linked to stronger cognitive performance in adults who face an increased risk of developing dementia.
The study included 54 adults with sleep disturbances and mild cognitive impairments (MCI), both of which can be associated with the early stages of dementia. Participants who reported taking at least 5,000 IU of vitamin D each day performed better on measures of cognitive function than those who did not take vitamin D.
