Low Vitamin B12 Levels in Older Adults May Lead to Low Cognition


Insufficient vitamin B12 is common in the older population due to decreased absorbtion, medications, or dietary changes such as limiting dairy and egg consumption. Chicago researchers followed a group of older adults for five years and found that low B12 levels may contribute to cognitive problems in multiple ways. This observational study did not say whether increasing B12 would prevent or reverse cognitive effects.

PositiveTip: For optimal health and brain function we all need adequate vitamin B12, either from dietary sources or from a supplement.
