Higher vitamin C levels linked to healthier brain structure, study finds
Fox News • • health
Key Points:
- A Japanese study published in PLOS ONE found that higher blood levels of vitamin C are associated with healthier brain structure, including greater gray matter volume and stronger connectivity in the default mode network (DMN) in older adults.
- The observational study involved 2,044 participants with an average age of 69 and used MRI scans alongside blood vitamin C measurements, controlling for factors like age, smoking, and diabetes.
- Researchers highlighted that vitamin C, obtained through diet from sources such as citrus fruits, berries, and leafy greens, may play a role in supporting brain health and cognitive function as people age.
- The study is limited by its observational design, a single blood measurement per participant, and its focus on an older Japanese population, so results may not be generalizable or prove causation.
- Experts note that while vitamin C is one factor influencing brain health, it should be considered alongside other established risk factors like blood pressure and blood sugar levels.
