A study involving over 2,000 Japanese individuals aged 64 and above found a strong connection between blood levels of vitamin C and brain connectivity, particularly within critical brain regions. Participants with lower plasma vitamin C levels exhibited reduced grey matter volume and diminished connectivity in the brain’s default mode network (DMN), a key system associated with cognitive functions such as attention and memory.
