Functions of B12

·         Vitamin B12 is an important molecule in both the nervous system (for mental functioning) and in carbohydrate metabolism (the production of energy).

·         Deficiency of Vitamin B12 has been linked to fatigue, inability to concentrate, changes in memory, and depression.

·         Injections of B12 have also been shown to improve symptoms associated with inflammatory changes including bursitis and sciatica, and to decrease homocysteine levels, a bio-maker which signals increased risk for heart disease and store.

·         Vitamin  B12 has been shown to decrease symptoms of fatigue, including that associated with Chronic Fatigue Syndrome and Fibromyalgia.

 

Why you might be deficient in B12

·         As we age, our body’s ability to digest foods high in B12 (beef, eggs, chicken) diminishes.

·         In addition, the body's ability to absorb B12 also decreases. B12 requires a special component in the small intestine for proper absorption, a property unique to B12 as opposed to our other vitamins.

·         B12 by intramuscular injection by-passes both the digestive and absorptive mechanisms that decrease with age so that the benefits of this valuable nutrient can be utilized.

·         Digestion of meats high in vitamin B12 is inhibited by certain medications, common examples include H2blockers and other reflux medications.  In addition, Glucophages used for blood sugar control decrease B12 absorption.

HOW OFTEN CAN YOU RECEIVE AN INJECTION?….

 

Frequency of injections depends on both presentation and response.  Generally, injections are recommended monthly, however we sometimes suggest a weekly dose for a few weeks before beginning monthly injections.  If not already a patient, a brief questionnaire must be filled out prior to your first injection.
