A study published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association found that higher levels of vitamin D in the brain were associated with better cognitive function and slower progression of cognitive decline. The researchers examined vitamin D levels in brain tissue from 290 participants, finding that elevated levels were linked to lower odds of dementia and mild cognitive impairment. Although the study did not find associations with certain dementia developments, the importance of studying how nutrients protect the aging brain was emphasized. Vitamin D can be obtained from fish and fortified foods, as well as through sun exposure, and may be beneficial for brain health. However, taking too much vitamin D can also pose risks and cause health issues. The recommended dietary allowance is 600 IU for those between ages 1 and 70, and 800 IU for those over 70. Research on exactly how vitamin D operates in the brain and how it affects diverse populations is ongoing. It’s important to consult with a doctor to determine the appropriate amount of vitamin D for an individual’s needs.
