Vitamin B12 influences a wide range
of bodily functions- by ensuring balanced B12 levels in your blood supply, you
feel more energized, stimulated, confident, and “gleeful.”

Vitamin B-12's primary functions are
in the formation of red blood cells and the maintenance of a healthy nervous
system. B-12 is necessary for the rapid synthesis of DNA during cell division.
This is especially important in tissues where cells are dividing rapidly,
particularly the bone marrow tissues responsible for red blood cell formation.
If B-12 deficiency occurs, DNA production is disrupted and abnormal cells
called megaloblasts to occur. This results in anemia. Symptoms include excessive
tiredness, breathlessness, listlessness, pallor, and poor resistance to
infection. Other symptoms can include a smooth, sore tongue and menstrual
disorders. Anemia may also be due to folic acid deficiency, folic acid also
being necessary for DNA synthesis. *
Sublingual B-12 gives your body the
vitamin B-12 nutrients it needs to naturally give you:
- Increased energy*
- Restored mental clarity, and help with memory loss *
- Reduced daily stress and irritability*
- And many other great health benefits *
Doctors know the health benefits of the
B vitamin family and have administered vitamin B-12 shots to patients for
years-patients who were feeling sluggish, tired, down, or forgetful-and they've
seen remarkable results.*
B-12 is also important in
maintaining the nervous system. Nerves are surrounded by an insulating fatty
sheath comprised of a complex protein called myelin. B-12 plays a vital role in
the metabolism of fatty acids essential for the maintenance of myelin.
Prolonged B-12 deficiency can lead to nerve degeneration and irreversible neurological
Some people have a medical problem
called pernicious anemia in which vitamin B-12 is not absorbed from the
intestine. Others may have a badly diseased intestine or have had a large part
of their stomach or intestine removed so that vitamin B-12 cannot be absorbed.
These people need to receive vitamin B-12 by injection.

Low levels of vitamin B12 can cause problems such as:
- Loss of balance
- Weight loss
- Poor memory
- Numbness or tingling in the extremities
Other conditions that may increase your need for vitamin B-12:
- Anemia, hemolytic
- Fever (continuing)
- Genetic disorders such as homocystinuria and/or methylmalonic
- Intestine diseases
- Infections (continuing or chronic)
- Kidney disease
- Liver disease
- Pancreas disease
- Stomach disease
- Stress (continuing)
- Thyroid disease
- Worm infections
- In addition, persons that are strict vegetarians or have
macrobiotic diets may need vitamin B 12 supplements.
- Increased need for vitamin B 12 should be determined by
your health care professional.
- Lack of vitamin B 12 may lead to anemia (weak blood),
stomach problems, and nerve damage.
Vitamin B-12 can be stored in small
amounts by the body. Total body store is 2-5mg in adults. Around 80% of this is
stored in the liver.
Vitamin B-12 is excreted in the bile
and is effectively reabsorbed. This is known as enterohepatic circulation. The
amount of B-12 excreted in the bile can vary from 1 to 10ug (micrograms) a day.
People on diets low in B-12, including vegans and some vegetarians, may be
obtaining more B-12 from reabsorption than from dietary sources. Reabsorption
is the reason it can take over 20 years for deficiency disease to develop in
people changing to diets absent in B-12. In comparison, if B-12 deficiency is
due to a failure in absorption it can take only 3 years for deficiency disease
What is B-12?
Vitamin B-12 is a member of the vitamin
B complex. It contains cobalt, and so is also known as cobalamin. It is
exclusively synthesized by bacteria and is found primarily in meat, eggs and
dairy products. There has been considerable research into proposed plant
sources of vitamin B-12. Fermented Soya products, seaweeds, and algae such as
Spirulina have all been suggested as containing significant B-12. However, the
present consensus is that any B-12 present in plant foods is likely to be
unavailable to humans and so these foods should not be relied upon as safe
sources. Many vegan foods are supplemented with B-12. Vitamin B-12 is necessary
for the synthesis of red blood cells, the maintenance of the nervous system,
and growth and development in children. Deficiency can cause anemia. Vitamin
B-12 neuropathy, involving the degeneration of nerve fibers and irreversible
neurological damage, can also occur.
The amount of vitamin B-12 actually
needed by the body is very small, probably only about 2 micrograms or 2
millionth of a gram/day. Unfortunately, vitamin B-12 is not absorbed very well
so much larger amounts need to be supplied through diet or supplementation.
The richest dietary sources of vitamin B-12 are liver, especially lamb's liver,
and kidneys. Eggs, cheese and some species of fish also supply small amounts,
but vegetables and fruits are very poor sources. Several surveys have shown
that most strict, long-term vegetarians are vitamin B-12 deficient. Many
elderly people are also deficient because their production of the intrinsic factor
needed to absorb the vitamin from the small intestine decline rapidly with age.
Fortunately, oral supplementation
with vitamin B-12 is safe, efficient and inexpensive. LifeSource Vitamins B-12
