Studies show that low vitamin D levels (<20 ng/mL) correlate with a 10% to 25% increased risk of Alzheimer’s and vascular dementia, while supplementation may reduce risk by 14% to 40%.
Vitamin D may protect the brain by reducing amyloid plaques, lowering inflammation, improving blood flow and acting as an antioxidant—though causation remains unproven.
While some studies suggest vitamin D lowers dementia risk, a 2023 study found long-term supplementation could increase risk in diagnosed patients, highlighting the need for further investigation.
Experts advise testing vitamin D levels (target 40–60 ng/mL), getting sunlight, eating vitamin D-rich foods (fatty fish, eggs), and supplementing (600–800 IU/day) if deficient.
Beyond vitamin D, proven strategies include exercise, Mediterranean diet, quality sleep, and avoiding toxins—emphasizing that no single factor guarantees prevention.
A growing body of research suggests that vitamin D—long known for its role in bone health and immune function—may also play a crucial role in protecting against Alzheimer’s disease and dementia.
