A vitamin has been named that can support the brain in old age

Scientists from Hirosaki University Graduate School of Medicine in Japan found that adequate vitamin C levels may be associated with better brain health in older adults. The results of the study were published in the journal PLOS ONE.

The researchers analyzed data from more than 2,000 people over the age of 64. They compared the concentration of vitamin C in participants' blood plasma with the results of magnetic resonance imaging of the brain.

It turned out that people with lower vitamin C levels more frequently exhibited a reduction in gray matter volume — brain tissue that plays a key role in information processing, memory, and thinking. In addition, they had weakened connectivity between regions of the so-called default mode network of the brain, which is involved in attention processes, self-reflection, and the preservation of autobiographical memories.

The association persisted even after accounting for other factors that could affect brain health, including age, education level, and physical activity.

According to the authors, the results point to a possible role of vitamin C in maintaining cognitive function in old age. The vitamin is known for its antioxidant properties and its ability to protect cells from damage associated with aging.

"This finding suggests that a diet rich in vitamin C may contribute to maintaining brain health and slowing age-related cognitive decline," noted study co-author Tomohiro Shintaku.

At the same time, the scientists emphasize that the study only identified an association between vitamin C levels and brain health but does not prove a cause-and-effect relationship. Additional studies involving more diverse population groups will be needed to confirm the results.
