Vitamin B12 Injections

Facts About Vitamin B12 Injections

Vitamin B12 is most effective when taken at regular intervals. B12 is a water-soluble vitamin, but unlike other vitamins, it is not excreted quickly in the urine. Small amounts of B12 may be stored in the liver and body fat tissues.

People with liver, kidney, Leber’s Disease (Hereditary Optic Neuropathy — a rare condition which can cause loss of central vision and/or sensitivity to cobalt, aluminum, benzyl alcohol or vitamin supplements), and women who are pregnant or breast feeding should consult their physician before taking a B12 injection and/or Vitamin B12 supplements.

Vitamin B12 Injections have been used for a long time, especially by many politicians and famous personalities in the entertainment industry.
There are several reasons WHY.

  • • The injection contains 500 times more vitamin B12 than the recommended daily dosage.
  • • When injected, vitamin B12 is easily absorbed by the body and then utilized in the formation of red blood cells, as well as aiding in the maintenance of a healthy nervous and cardiovascular system.
  • • The 3 major health benefits of vitamin B12 injections are an increase in energy, improved sleep patterns, and a feeling of alertness.

Vitamin B12 — Is It Right for You?

By Bill Caradonna, RPh, ND

A half-century ago, MDs commonly administered vitamin B12 shots to their patients.As prescription drug development and use increased, vitamin B12 use declined.As naturopathic physicians have re-emerged in the health care picture, so has vitamin B12 use.

Why Is Vitamin B12 So Important?

Vitamin B12 helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA, the genetic material in all cells.While it is well known to prevent pernicious anemia, it can also play an important role in preventing fatigue, insomnia, depression, cardiovascular disease, nerve damage, loss of appetite, soreness of the mouth or tongue, poor memory and senile dementia. It has also been helpful in certain types of arthritis, asthma, infertility, multiple sclerosis, shingles and ringing in the ears.

Why Do B12 Deficiencies Exist?

Vitamin B12 is naturally found in meat, poultry, fish, dairy products, eggs and fortified breakfast cereals. However, it can be difficult to absorb from animal products, especially in people with certain digestive imbalances. One cause is low hydrochloric acid in the stomach.This can be aggravated by chronic use of prescription and non-prescription acid blockers (like Prilosec). Low HCL is also common in elderly populations.The presence of a bacterium associated with stomach ulcers has also been associated with low B12 levels.

B12’S Impact

B12 shots deliver far more B12 into the system than supplements, and avoid absorption difficulties. B12 is virtually non-toxic and, for most people, the shots are nearly painless. Below are several conditions for which B12 has been shown to be valuable.


Fatigue can be present for many reasons.These include lack of sleep, inadequate nutrition and lack of stable blood sugar levels, use of stimulants that cause the body to “crash” a few hours later, and long-term stress. In the absence of diagnosed anemia, many people find that B12 gives them an energy boost, both short- and long-term. Athletes have reported increased endurance as well.


People often report improved sleep with B12 shots.Vitamin B12 influences melatonin secretion, which tells the brain to go to sleep. Winter depression also has been linked to imbalanced melatonin levels.


Research shows that those who suffer from depression respond better to drug treatment if they have high levels of vitamin B12 in their blood. One theory states vitamin B12 helps play a role in the manufacture of brain chemicals, a shortage of which is believed to be linked to depression. Another theory is that people diagnosed with depression have low plasma levels of cobalt, the mineral that forms the center of the B12 molecule.

Heart Disease

Homocysteine, a nerve and blood vessel toxin, is produced by imbalanced biochemical processing in the body. It has been associated with higher levels of death by heart disease and stroke. The cause of this production has been tied to deficiencies of several B vitamins, including B12. High levels of Homocysteine have also been predictive of increased incidences of dementia and Alzheimer’s disease.

Deficiency And The Elderly

It is especially important to diagnose B12 deficiency early in the elderly because it can lead to permanent impairment of neurological and mental function if left untreated. Identifying low B12 levels that can result in nerve damage is more difficult to diagnose.

Low B12 levels in the tissue, not the blood, can cause this problem. Measuring tissue B12 levels requires a special urine test.

What is Vitamin B12?

Vitamin B-12 plays a key role in the normal functioning of the brain and nervous system and the production of red blood cells. It is normally involved in the metabolism of each cell in the body, and also helps metabolize fats proteins, and carbohydrates for energy production.

Vitamin B12 deficiency sometimes results in anemia, therefore, the injections have been used to treat patients with chronic fatigue and anemia.

The vitamin is found in animal products, such as meat, eggs, and milk. Because the absorption process is so complicated, and is subject to various blocks in the absorption process, many people may develop deficiencies even though they are taking in plenty of Vitamin B12 through their diet.

In general, Vitamin B12 injections are helpful in promoting an inner balance and overall sense of well-being.

Benefits of Regular Doses of Vitamin B12 Injections

The reported benefits of regular doses of Vitamin B12 Injections are more energy & stamina for daily life activities, healthier or improved immune system, improved sleep patterns, reduced allergies, reduced stress, reduced depression, improved moods and less frequent and severe headaches.
