Low Vitamin B12 Levels in Older Adults May Lead to Low Cognition
Posted by Fred Hardinge on
Low levels of B12 may affect global cognitive scores in older adults.
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.

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