Summary
MRI scans and blood tests from 2,044 Japanese adults over 64 showed lower plasma vitamin C was associated with less gray matter and weaker connectivity in the brain’s default mode network.
After adjusting for age, education and physical activity, researchers still found the same pattern, tying higher vitamin C levels to better-preserved brain structure linked to memory and attention.
PLOS One published the observational study on June 10, but the authors said it does not prove vitamin C directly protects the brain or slows cognitive decline.
Future work will need repeated vitamin C measurements and broader populations to test whether diet rich in vitamin C can help support healthy brain aging.
