This study involved 54 adults who had both sleep problems and mild cognitive impairment, a condition in which memory or thinking abilities have declined beyond what would normally be expected with aging but have not yet progressed to dementia.
Participants who reported taking at least 5,000 IU of vitamin D per day achieved scores on a widely used test of cognitive ability that were more than 13 percent higher than those of people who did not take the nutrient daily. The difference remained after the researchers took other potentially relevant factors into account. Lower daily amounts of vitamin D were not associated with better scores, and there was no significant difference according to whether participants took vitamin D2 or vitamin D3.
The researchers say that people who have both sleep disturbances and mild cognitive impairment may be at an important stage when measures to protect brain health could still make a difference. Vitamin D is already known to play important roles in nerve and muscle function and has also been linked to the regulation of sleep. The findings suggest that vitamin D supplementation deserves further investigation as a simple and accessible approach for supporting cognitive health during the early stages of decline.

With more than 7 million Americans living with Alzheimer’s dementia – a number projected to reach nearly 13 million by 2050 – new Emory University research suggests that higher vitamin D supplement intake may be associated with better cognitive function in adults at elevated risk of dementia.
