New research suggests that higher vitamin D supplement intake can help brain health. Scientists look at adults who have a higher risk of developing dementia. Millions of people live with Alzheimer's disease today, and this number grows every year.
A recent study examines fifty-four adults with sleep problems and mild memory issues. The research compares people taking a large daily dose of vitamin D with people who do not take it. Participants taking at least five thousand international units of vitamin D score higher on a common memory test.
The study also shows that different forms of vitamin D give similar results. Experts explain that older adults with sleep and memory issues are in an important window for intervention. Vitamin D is an essential nutrient that supports the body and helps sleep quality.
