Are There any Resulting Repercussions of Vitamin B12 Deficiency?

Water-soluble vitamin B12 is present in some easily available foods, can be added to
manufactured ones, and as a supplementation in some cases. It exists in more than one form and
uniquely contains cobalt ion, where the name `cobalamins' is derived which depicts different forms
of the vitamin.

Laboratory Test for B12 Deficiency and Treatment

Patients who exhibit symptoms of vitamin B12 deficiency are subjected to diagnostic tests in
certified clinical laboratories by their doctors so as to find out if they have any underlying health
conditions. Such diseases may include anemia and neuropathy. Anemia is a deficiency in blood
characterized by low oxygen transport.

Other reasons why a doctor might be interested in taking you through a vitamin B12 test in a
clinical laboratory is to ascertain your nutritional status so as to ensure that you are taking the right
amounts of all necessary nutrients, especially if you have been anaemic. In such cases, there
might also be an interest in finding out the efficacy of your treatment.

Even though blood test results are taken to evaluate the nutritional or disease status of individuals,
concentrations of serum vitamin B12 may sometimes not accurately indicate intracellular
concentrations. Other tests are run because an increased serum homocysteine level may as well
suggest deficiency of Vitamin B12.

Usually, quality medical practitioners will explain to you in a one-on-one discussion about the
implications of different levels of vitamin B12 according to test results. They can even suggest to
you some complementary tests like methylmalonic acid level tests that you could take. Online, you
can find a lot of information on vitamin B12 injections and supplements; you might even find that
some people even use B12 injections to aid in weight loss.

What are the Sources of Vitamin B12?

Cyanocobalamin or vitamin B12 is stored up by human liver and kidneys and can be reserved
there for use when the body so demands going on without depletion for more than 6 years. Folate
or vitamin B9 is another vitamin whose function closely relates to that of cyanocobalamin and can
be stored in human liver for 5 months. It is only bacteria that manufacture B12.

Food products containing vitamin B12 include clams, liver, beef, trout, salmon, tuna fish, cheese
burger, double patty and bun, low fat milk, whole or hardboiled egg, chicken, and roasted meat,
cheese, beef taco, ham and cooked haddock. Formulation of fortified foods varies and one needs
to check on availed labels to determine the added nutrients.


Vitamin B12 is normally present in dietary fortified foods as methylcobalamin among other FDA
approved forms. Though differences among forms are not with regard to absorption or
bioavailability, its absorption from supplements is largely limited by the capacity of intrinsic factor
to cause it to be ferried from the gut.

Oral dietary supplements are not the only way in which vitamin B12 can be supplied into the body.
In modern times, it is available in sublingual preparations as lozenges or tablets. Many advertisers
market such forms as having superior bioavailability (biologically utilizable content). A protein
known as intrinsic factor is the determinant of how much an individual can absorb vitamin B12.
This means that though there are marketers who often claim that one product is superior to others
all ingested dietary supplements must be subject to the capacity of intrinsic factor proteins. Need

In diagnosis of vitamin B12 deficiency, a doctor might recommend that one takes blood tests so as
to have the level of this essential vitamin evaluated. Early diagnosis and subsequent intervention
is needed so as to avoid irreversible damage. Typically, vitamin B12 injections are used to
effectively treat the condition.
