Vitamin C and elderly brain health study

A study published in PLOS One by researchers at Hirosaki University in Japan has identified a link between Vitamin C levels and brain health in the elderly. Analyzing data from over 2,000 Japanese seniors, the research suggests that higher blood plasma Vitamin C levels are associated with better-preserved gray matter volume and improved connectivity within the Default Mode Network (DMN), a system responsible for functions such as attention, memory, and reflection.

The correlation remained statistically significant after adjusting for various factors, including age, gender, education, physical activity, smoking, alcohol consumption, diabetes, blood pressure, and blood lipids. While the findings indicate a relationship between Vitamin C and brain structure, researchers noted that the cross-sectional nature of the study means it cannot prove that Vitamin C consumption directly prevents cognitive decline. They emphasized that a balanced diet rich in fruits and vegetables is preferable to high-dose supplementation.
