Higher Vitamin C Levels Linked to Healthier Brain Aging

As the human brain quietly loses volume and connectivity with each passing decade, researchers have found a humble nutrient — vitamin C — standing in quiet correlation with its preservation. A study examining blood plasma levels alongside brain imaging in older adults reveals that those carrying more ascorbic acid in their bloodstream tend to retain greater gray matter volume and stronger neural connectivity. The finding does not yet prove causation, but it places something as ordinary as a piece of fruit within the larger conversation about what we owe our aging minds.
