About Vitamin B12 Injections

Vitamin B12 injections are only administered when there is no other way of supplementation. Injections are mostly used in cases of diseases caused by vitamin B12 deficiency. Injections are usually administered to people who have a medical problem known as pernicious anemia, a condition in which the patient is not capable of absorbing vitamin B12 via the intestine. Injections are also administered to those who suffer from a diseased intestine or have a large part of their stomach or intestines removed. Vitamin B12 injections are only given by or under the supervision of a health care professional. In the United States, injections of vitamin B12 are generally available in two types, cyanocobalamin and hydroxocobalamin.    

Advantages of Vitamin B12 Injections

Vitamin B12 injections have been used for a long time, especially by many politicians and famous personalities from 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 three major health benefits of vitamin B12 injections are an increase in energy, sleeping better, and a feeling of alertness.  However, people often complain of bruises and soreness in the area where the vitamin B12 was injected.

Supplementation of Vitamin B12
Oral supplementation of vitamin B12 is safe and inexpensive. The problem with oral supplementation of vitamin B12 is its complex absorption process within the body. This is mainly due to the fact that vitamin B12 must be converted to methylcobalamin or adenosylcobalamin in order to be absorbed by the body. With oral supplements the actual absorption of vitamin B12 is often a lower dosage than needed.  In case of a deficiency a daily dosage of 2000 micrograms for at least a month is recommended, which later on can be lowered to 1000 micrograms. Many physicians prefer supplementation through injections.  Vitamin B12 injections are required to maintain adequate levels of this vitamin in the elderly and in those patients who are diagnosed with a deficiency.

An Overview Of Intravenous Vitamin B12
 Vitamin B-12 is necessary for many things, including growth, cell reproduction, and hematopoiesis. Generally vitamin B12 is administered in the form cyanocobalamin, which is absorbed in the muscles at the site of the injection. The level of plasma in the compound is found to be at its peak within an hour after the intramuscular injection is given. Almost 1000 micrograms, that is 50- 98 percent of vitamin B12, is present in the urine within 48 hours of the injection. Most of vitamin B12 is excreted in the urine. Some vitamin B12 is also absorbed through the intestinal tract.
