Overview
Preliminary findings indicate a link between daily vitamin D intake and cognitive scores in a specific older adult population. Older adults with both mild cognitive impairment and sleep problems who ingested at least 5,000 international units (IU) of vitamin D per day registered cognitive test scores over 13% higher than individuals with the same conditions who reported no vitamin D intake.
Findings
- Older adults with mild cognitive impairment and sleep problems who consumed at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test.
- This enhanced cognitive performance was observed in comparison to a group of individuals with mild cognitive impairment and sleep problems who took no vitamin D.
Why This Matters
The preliminary findings suggest that vitamin D could be considered a potentially modifiable factor. This factor may warrant further study specifically during an early window of cognitive decline, given its observed association with cognitive scores in a defined cohort.
