CZA new study published in June 2026 suggests that higher levels of vitamin C in the blood may be associated with better structural connectivity in the brain’s default mode network (DMN), which plays a role in memory, focus, and processing memories. Researchers from Japan’s Hirosaki University analyzed data from over 2,000 people aged 64 and older and found that those with lower vitamin C levels had smaller volumes of gray matter and weaker DMN connections. These findings align with previous research linking adequate vitamin C intake to a reduced risk of Alzheimer’s disease. However, the researchers emphasize that their study was observational and does not prove causation—vitamin C may simply be an indicator of healthier lifestyles rather than a direct cause of improved brain health. Further long-term studies are needed to confirm these associations.
