Vitamin B12 is a vital element required in the smooth functioning of the human body. Even though about 2-5 mg of B12 is stored in an adult human body, a lack of presence of this vitamin may have severe implications for the healthy running of bodily functions. The main form of excretion of B12 is bile and the largest storehouse of this vitamin is the liver, keeping about 50% of the entire amount present. We must note that due to efficient enterohepatic circulations of B12, several years of the accumulated vitamin can be stored in the liver. Since a small fraction of it is lost daily by secretions to the gut, the speed at which dietary intake may causes vitamin B12 deficiency depends on the gap between absorption from food and secretions into the gut. The occurrence of a deficiency is dependent on not only low initial supplies in the body, but also unfavorable genetic factors. The time of occurrence can be in the infant stages or in old age.
Artificial supplements of this vitamin can be taken in, in different ways, over which there is much contention – orally, with the help of nasal sprays, and via injections. A highly effective and tested cure for those suffering from a deficiency, however, is the use of vitamin B12 injections. These are often used for a speedy recovery.
Those people who suffer from pernicious anemia are regularly injected with B12 supplements. Such anemic patients fail to derive the vitamin in their day to day diet and hence have to rely on intramuscular injections to help in absorption process. Even though there are oral methods available, injections are recommended by one and all.
Much research has pointed out that cobalamin injections with dosages ranging from 1 mg to 2 mg can help rectify inadequacies if used on a daily basis. It has not been substantiated with evidence whether the 25 mcg multi vitamin pills are good enough to fix deficiencies. They are, however, in use due to their safety and efficiency coupled with the fact that they’re inexpensive. But grave drawback of taking oral supplements is that most of these tablets cannot be chewed which is highly essential for its absorption.
It has been empirically shown that neurological disorders such as memory loss and lethargy can be cured by B12 injections. A dose of 1 mg a month of intramuscular injections serves as a useful alternative to oral methods of B12 supplements. It is useful to note how injecting vitamins can help reduce the occurrence of strokes and heart diseases. This essentially is a result of lower homocysteine levels in the blood.
Even though the primary purpose of vitamin B12 injections is to cure deficiency, it has other utilities. It can be successfully implemented for therapeutic purposes. Acting as a stimulant to energize the human body, it does so by the transmission of anti stress elements in the blood stream.
CFS or chronic fatigue syndrome is a disease, the cure for which is recommended as intramuscular vitamin B12 injections, whose dosages may vary from 6-7 mg of vitamin B12 per week. This however is to be continued for 3 weeks in order for the cure to be fully effective.
