Scientists have discovered a link between vitamin C levels and brain health in older adults
Higher levels of vitamin C in the blood may be associated with better brain health in older adults.
Researchers at Hirosaki University analyzed data from more than 2,000 people aged 64 and older and found that participants with lower vitamin C levels were more likely to have lessgray matter volume and weaker connections between key brain regions responsible for memory, attention, and cognitive functions.
To assess brain health, the scientists used magnetic resonance imaging (MRI) and blood tests, which allowed them to compare nutrient levels with structural features of the brain.
The study specifically analyzed the default-mode network—a system of interconnected brain regions that plays a key role in memory, thinking, and internal information processing.
After accounting for factors such as age, education level, and physical activity, the researchers found a consistent association between lower vitamin C levels and poorer brain structure and functional connectivity.
At the same time, the authors emphasize that the study is observational in nature and therefore does not confirm that vitamin C directly improves brain function.
The researchers note that the observed association may also be explained by other lifestyle factors that influence both nutrient levels and brain health.
Despite these limitations, the study’s findings provide further evidence that a balanced diet may play an important role in preserving cognitive function in older age.
The researchers emphasize that long-term studies with larger sample sizes are needed to definitively confirm this link, which will help determine whether vitamin C can indeed influence the brain’s aging processes.
