Vitamin D Boosts Brain Health in Early Dementia | Health and Fitness News
Description
New research reveals that older adults with early signs of dementia and sleep issues who took 5,000 IU of vitamin D daily scored over 13% higher on cognitive tests — a powerful boost not seen with lower doses. This small but pivotal study highlights vitamin D’s potential as a simple, modifiable intervention during the earliest stages of cognitive decline, especially when paired with sleep disturbances. Both D2 and D3 showed similar benefits, suggesting vitamin D may support brain health by improving nerve function and sleep — two critical factors in Alzheimer’s progression. While preliminary, these findings offer hope for a practical, accessible strategy to protect cognitive function in at-risk populations.
