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.”
is instrumental in DNA synthesis*

supports cognitive functioning*
protects you from vitamin deficiency symptoms of fatigue, depression,
anxiety, and “brain fog”*

make better food choices*
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:
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
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 damage.*
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
Numbness or tingling in the extremities
Other conditions that may increase your need for vitamin B-12:
Genetic disorders such as homocystinuria and/or methylmalonic aciduria
Infections (continuing or chronic)
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
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 to occur.
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 provides the necessary amount of the
vitamin to help from becoming B-12 deficient.
