A recent study conducted by researchers at Emory University has shown a potential link between high daily vitamin D intake and improved cognitive function in individuals with mild cognitive impairment and sleep disorders. This finding could have significant implications for those at risk of developing Alzheimer’s disease.
Vitamin D is not only essential for muscle and nerve function but also plays a role in influencing sleep quality and sleep-wake cycles. Sleep disturbances are common among patients with mild cognitive impairment, and addressing these issues early on could potentially slow down cognitive decline.
The study included 54 participants with mild cognitive impairment and sleep problems who were asked to complete the Montreal Cognitive Assessment. Those who reported taking more than 5,000 international units (IU) of vitamin D daily showed higher cognitive test scores compared to those who did not take vitamin D supplements.
Interestingly, the form of vitamin D (D2 or D3) did not seem to impact cognitive performance, suggesting that the benefits may be derived from overall vitamin D intake rather than the specific type.
Lead author Dr. Victoria Pack emphasized the importance of identifying and addressing modifiable factors like vitamin D supplementation in the early stages of cognitive decline. With Alzheimer’s disease rates on the rise, proactive measures to support brain health are crucial.
This study, published in the October 2026 issue of the journal Sleeping Pills, sheds light on the potential benefits of vitamin D supplementation for individuals with mild cognitive impairment and sleep disorders. Further research in this area could provide valuable insights into interventions for cognitive health.
