This study links higher blood vitamin C to healthier brain structure, but it can't prove cause.
In older adults, people with more vitamin C in their blood tended to have more gray matter and better connections in a key brain network. This held up even after accounting for age, education, and conditions like diabetes. It's a snapshot in time, so it can't prove vitamin C protects the brain.
