Importance of Vitamin B-12

Vitamin B12

Vitamin B12 helps the body make red blood cells. It also aids nerve and brain function.

B12 is bound to the protein in animal products. Younger adults usually get plenty of this key nutrient by eating meat, poultry, fish, eggs, milk, and fortified cereals.

Older adults lose the ability to separate B12 from protein, which can cause a deficiency. The Institute of Medicine recommends that adults over age 50 take B12 supplements, which are easier to absorb. Vegetarians who don’t eat breakfast cereals may also need supplements.
