Emory Study Links High-Dose Vitamin D to Improved Cognitive Scores in At-Risk Seniors
A new observational study from Emory University indicates that older adults with mild cognitive impairment and sleep disturbances may experience better cognitive performance when taking high daily doses of vitamin D. The research, published in the journal Sleep Medicine, suggests that supplementing with 5,000 international units or more daily is associated with higher scores on standard cognitive assessments. While the study does not prove causation, it highlights vitamin D as a potentially modifiable factor for supporting brain health in individuals at elevated risk for progressing to Alzheimer's disease.
