A serious Vitamin B12 deficiency called Hypocobalaminemia can cause severe and irreversible damage to the brain and nervous system if not treated in a timely manner, and if serious enough and left untreated can even lead to death. Luckily the body has the ability to store sufficient amounts of Vitamin B12 for long periods of time and may be reabsorbed. However, recent studies have effectively proven that most deficiencies are as a result of poor absorption ability, not low consumption.
Many foods we buy today are fortified with vitamin b12 because it is such an important vitamin and is usually only found in meats and foods of animal origin such as milk and eggs, leaving vegans and vegetarians at risk for deficiency. But studies have also shown that a very large portion of the population, vegetarians and non-vegetarians, and more than was originally thought, are vitamin B12 deficient. This indicates that vitamin b12 is more difficult to absorb through regular ingestion than we like to think.
Some of the symptoms of a Vitamin B12 deficiency are anemia, gastrointestinal problems and difficulty with metabolism, sensory or motor deficiencies, tingling, prickling, numbness or burning sensation of the skin, impaired sense of touch, impaired sense of depth of touch and pressure of touch and decrease in muscle-tendon reflexes. Psychological symptoms may include irritability, lack of ability to focus or concentrate, impaired memory, depression or psychosis and mania.
Treating Vitamin B12 deficiency can be accomplished through many routes including b12 injections. As we age, our body’s ability to absorb vitamin B12 reduces and the regular routes of administration become less effective. There are many illnesses as well that have the same effect on absorption capability. The most effective method of absorbing B12 back into the body is with Vitamin B12 injections.
One very popular b12 injections benefit which is used often is for weight loss. There is a lot of controversy over the effectiveness of b12 for weight loss, but there are many doctors who prescribe it for just this, usually in the form of b12 shots. Vitamin B12 is used by the body for fatty acid synthesis and the production of energy. It helps with metabolism, and in this manner is also helpful for weight control. While providing higher levels of energy it may also be responsible for increased activity levels, giving the user more of an edge over weight loss or weight control. Vitamin B12 is water soluble, so is not toxic in higher doses. It leaves your body via natural elimination.
You can actually buy kits to administer your own Vitamin B12 injections, however it is a good idea to first talk with your doctor and ask to have blood tests done to determine if you actually are deficient and to discuss the safety factor in administering your own b12 shots. If it is a weight loss program you are looking for, also discuss this with your doctor. For more information on B12, I would highly recommend this article by Chris Kesser.
