Vitamin B12 and the brain

Seniors with low levels of vitamin B-12 may be more at risk for brain shrinkage and problems with memory and thinking.

Researchers have linked signs of a B-12 deficiency with smaller brain volume and poorer cognitive scores.

Experts say it’s too early to tell if B-12 supplements would help.

The vitamin is found most commonly in animal products, like meat and eggs.

As we age, the vitamin appears herder to absorb by the body.
