- Vitamin D and Dementia
Vitamin D protected against developing Alzheimer’s disease and other forms of dementia. Doctors measured levels of vitamins A, D, E and beta-carotene in 1,334 people who were free from dementia at the start of this seven-year study.
One-third (33.7 percent) had optimal vitamin D levels of at least 50 nanomoles per liter of blood (nmol/L) or 125 nanograms per milliliter (ng/mL) and were less likely to have developed any form of dementia. Those who were deficient—less than 25 nmol/L or 62.5 ng/mL—were 91 percent more likely to have developed any dementia, and 128 percent more likely for Alzheimer’s.
