Are You B12 Deficient?

Chances are you may be one of the almost 40% of the U.S. population that have suboptimal vitamin B12 levels. Fully 9% are well below the current deficiency level. Vitamin B12 deficiencies can progress very slowly, as initial signs and symptoms may appear gradually and intensify over time. B12 deficiency can also come on quite suddenly and many times symptoms can be overlooked or chalked up to other factors. Symptoms of deficiency can include, among others, anemia, balance issues, numbness or tingling in the hands or feet, cognitive difficulties, mood swings, muscle weakness, infertility, lack of energy and fatigue. A simple blood test can detect a B12 deficiency. Early detection and treatment are crucial, as untreated deficiency may result in neurological problems, blood disorders or premature death.  

B12 is a requirement for a number of bodily functions and is essential for the health of every cell in the body. This powerhouse nutrient is involved in physical, mental and emotional energy production, cognitive function, the regulation of red blood cells, DNA synthesis, healthy immune and nervous system function, proper digestion, cell formation and longevity, hormone production, and myelin formation, which protects nerve endings and allows communication between nerve cells.

The most common causes of deficiencies are inadequate dietary intake and malabsorption issues. Although B12 deficiency can affect all age groups, those who are most at risk for lifetime deficiencies include:

  • The elderly or those over 50 years of age who are most likely to have malabsorption issues due to a decrease or gradual loss of gastric acid, which releases the vitamin from food. According to scientists at Rush University Medical Center, elderly people with B12 deficiency are more likely to suffer from cognitive decline.
  • Deficiency is very common in strict vegans or vegetarians, as B12 is present only in animal products or fortified foods.
  • Those who take prescription or OTC acid reducing medications which lower stomach acid, compromising the body’s ability to extract and absorb B12 and other dietary nutrients.
  • Diabetics who take diabetes medications such as Metformin©, which may interfere with the metabolism of calcium necessary for B12 absorption.
  • Those who have malabsorption issues, such as those with celiac or Crohn’s disease.
  • Those who may have had gastric bypass weight loss surgery.
  • Those with pernicious anemia, an autoimmune condition in which the body is unable to produce intrinsic factor, a binding protein necessary for B12 absorption. Without intrinsic factor, the body simply cannot absorb vitamin B12.
  • Those who have or have been affected by Helicobacter pylori, which can damage the stomach cells that produce intrinsic factor.
  • Those who consume 4 or more cups of coffee daily are likely to be slightly deficient in B12.
  • Medications that can result in B12 deficiencies include antibiotics, anticonvulsants, birth control pills, cholesterol-lowing pharmaceuticals and Parkinson’s disease medications.

Though largely unrecognized, vitamin B12 deficiency can have serious consequences and is preventable in most cases. For the most serious cases, treatment options can include weekly vitamin B12 injections or daily high dose supplements. For milder cases, fortified foods and a standard B complex vitamin may be enough to correct deficiencies. Over age 50, supplements in highly absorbable form are recommended, as aging is a factor in malabsorption from foods. If you are B12 deficient, the first step is to identify the underlying cause of the deficiency in order to find the appropriate form of supplementation.
