Genetics Confirm Vitamin D Role
- Genetically low vitamin D levels causally increase dementia risk by up to 54%.
- This strengthens the evidence that vitamin D deficiency is not just a marker but a cause of dementia risk.
Vitamin D Protects Brain Structure
- Higher vitamin D levels reduce brain white matter hyperintensities linked to cognitive decline.
- This suggests vitamin D protects against brain damage that accelerates aging.
Vitamin D Improves Cognition Biomarkers
- Vitamin D supplementation (800 IUs daily) improves cognition in Alzheimer's and mild cognitive impairment patients.
- It also lowers blood markers of Alzheimer's disease progression, like amyloid beta 42.
