Summary
MRI scans and blood tests from 2,044 Japanese adults aged 64 and older found lower plasma vitamin C was associated with less gray matter and weaker connectivity in the brain’s default mode network.
The analysis adjusted for age, physical activity and education, suggesting the link was not explained solely by other common drivers of brain health.
The default mode network helps support memory, attention and self-reflection, making the weaker connectivity finding relevant to age-related cognitive decline.
Researchers said the results add to evidence tying nutrition to brain health, but the PLOS One study was observational and did not prove vitamin C preserves the brain.
