Vitamin B12 tied to Alzheimer's
Vitamin B12 may help protect against Alzheimer's disease, according to a recent study.
The study suggests that seniors with more of the active part of the vitamin in their blood have a lower risk of developing the disease.
Many elderly people suffer from B12 deficiency. However, the findings do not necessarily mean that taking B vitamin supplements will stave off mental decline.
Vitamin B12 is found in a variety of foods, including dairy, eggs, fish and meat. Too much folate in the presence of B12 deficiency can be harmful.
