Is Vitamin D Associated with Lower Levels of Alzheimer’s Biomarkers?
A longitudinal study of 793 adults tracked vitamin D levels at an average age of 39 and brain‑scan biomarkers 16 years later. Participants with serum vitamin D above 30 ng/mL showed significantly lower tau protein accumulation, a key Alzheimer’s marker, while no link was found with amyloid‑beta. The association persisted after adjusting for age, sex and depression, but the study relied on a single baseline vitamin D measurement. Researchers caution that vitamin D may be a proxy for overall health rather than a direct neuroprotective agent.
