Recent research has identified a serious vitamin B-12 deficiency among many seniors. The researchers estimated that as many as 40% of Americans have low levels of vitamin B-12. Making matters worse some of the drugs used to reduce stomach acid tend to increase the deficiency. In fact more than 20% of seniors over the age of 65 suffer from severe B-12 deficiency. Unfortunately the symptoms of B-12 deficiency may go undetected, because they are subtle. B-12 deficiency has been identified as a link to age-related dementia, cognitive impairment, and depression. Even mild B-12 deficiency may be a contributor to Alzheimer’s disease. Getting adequate B-12 in their diet is obviously a preemptive aging measure that will contribute to senior health.
On the positive side B-12 plays a critical role in breaking down homocystene that contributes heavily to the development of a number of chronic diseases including heart disease, stroke, and rheumatoid arthritis. It turns out that B-12 works synergistically with folic acid to reduce high levels of homocystene. Getting absorption of adequate amounts of B-12 can be a problem for seniors, because of changes in the stomach linings of seniors. This absorption problem means that eating foods that contain B-12 such as meat, milk, and eggs will not help. Taking oral supplements of B-12 may not succeed either, because it is not adequately absorbed. Taking B-12 by injection has its own limitations. Two other approaches offer hope for achieving adequate absorption by seniors. B-12 can be taken sublingually or by one of the newer oral supplements.
