🧠Low vitamin C in the blood linked to less brain gray matter in a 2,000-person Japan study

Researchers analyzing data from more than 2,000 older adults in Japan found that people with lower blood vitamin C levels tended to have less gray matter volume in their brains. The pattern held broadly across the group, suggesting the common vitamin may play an underappreciated role in maintaining brain structure with age. It is observational, so cause and effect are not yet established — but the correlation is hard to ignore. Do you think vitamin C supplements could actually protect the aging brain?
