Could a Common B-12 Deficiency Be Causing Your Symptoms?

Less than 20 years ago, patients complaining of fatigue were often given a "tonic shot" by their doctor. Many people claimed this worked like magic to improve their energy levels. What was this miracle tonic? A simple injection of vitamin B-12.

Although the practice of administering vitamin B-12 injections has fallen out of favor, modern medical science now understands why vitamin B-12 supplementation makes people feel better, and the reasons extend far beyond just the "placebo effect" of receiving a shot.

The Far-Reaching Effects of Vitamin B-12 Deficiency

Vitamin B-12, called "cobalamin" because it contains the mineral cobalt, is required for a staggering number of physical functions and chemical reactions. Best known for its participation in the manufacture of red blood cells, B-12 is also needed for production and maintenance of the myelin sheath that surrounds nerves and for production of DNA, the genetic material of all cells. And that’s just the beginning.

The serious health consequences of vitamin B-12 deficiency can adversely affect nearly every system in the body.

Energy: Even minor deficiencies of vitamin B-12 can cause anemia, fatigue, shortness of breath and weakness.

The Nervous System: Deficiencies of B-12 can cause neurological changes including numbness and tingling in the hands and feet, balance problems, depression, confusion, poor memory and Alzheimer's-like symptoms. Long-term deficiencies of B-12 can result in permanent impairment of the nervous system.

The Gastro-Intestinal System: B-12 deficiency can cause decreased appetite, constipation, diarrhea or alternating constipation/diarrhea, weight loss and abdominal pain.

The Immune System: Vitamin B-12 is necessary for normal functioning of white blood cells. Studies show that B-12 helps regulate Natural-Killer T-cells and prevents chromosome damage.

The Cardiovascular System: Vitamin B-12 participates in the conversion of homocysteine to methionine. Elevated homocysteine levels are a known independent risk factor for heart attack, stroke and thrombosis. Without adequate B-12 levels, homocysteine levels typically rise.

Special Senses: Degenerative changes in the central nervous system caused by B-12 deficiency can also affect the optic nerve, resulting in blue-yellow color blindness.

Other symptoms of vitamin B-12 deficiency include sore mouth or tongue.

With so many physical functions at risk, it is easy to understand why knowledgeable clinicians and researchers consider B-12 supplementation beneficial.

Are You At Risk for a Vitamin B-12 Deficiency?

Medical science once believed that few people were vitamin B-12 deficient. This false assumption may stem from the fact that vitamin B-12 is produced in the body by a normal, healthy population of bowel bacteria.

Secondly, unlike other water-soluble vitamins, B-12 is stored in the liver, kidneys and other tissues. Deficiencies of B-12 often appear so slowly and subtly as to go unnoticed, and blood tests for vitamin B-12 levels miss early deficiency states at least 50% of the time.

So, who is at risk for vitamin B-12 deficiency? Recent research shows that a much larger segment of the population is likely deficient than previously thought...
