Vitamin B12 Deficiency: A Common Health Problem That Can Have Serious Consequences


“Vitamin B12 deficiency is a common health problem that affects an estimated 6 to 20 percent of the U.S. population – but doctors often overlook it.” [Source: Medicalexpress.com]


Vitamin B12 functions as a cofactor for key enzymes involved in the synthesis of DNA, fatty acids, and myelin. An insufficient supply of this nutrient can lead to blood disorders and neurological problems. Severe deficiency can result in pernicious anemia, a potentially fatal disease that is characterized by an insufficient production of red blood cells.

Research shows that a significant proportion of older adults are deficient in vitamin B12. Low levels are known to worsen Parkinson’s disease and increase the risk of depression, as well as being associated with dementia and cognitive impairment. A lack of this nutrient has additionally been linked to behavior problems in young boys and the progression of liver fibrosis in non-alcoholic fatty liver disease.
