Vitamin B12 (Cyanocobalamin) 120 mcg
The
U.S. RDA for vitamin B-12 is 6 micrograms per day. Vitamin B12 helps
maintain healthy nerve cells and red blood cells. It is also needed to
help make DNA, the genetic material in all cells. Vitamin B12 is also
called cobalamin because it contains the metal cobalt.


Vitamin
B12 is bound to the protein in food. Hydrochloric acid in the stomach
releases vitamin B12 from proteins in foods during digestion. Once
released, vitamin B12 combines with a substance called intrinsic factor
(IF). This complex can then be absorbed by the intestinal tract.
Characteristic signs, symptoms, and health problems associated with
vitamin B12 deficiency include anemia, fatigue, weakness, constipation,
loss of appetite, and weight loss.
Deficiency also can lead to
neurological changes such as numbness and tingling in the hands and
feet. Additional symptoms of vitamin B12 deficiency are difficulty in
maintaining balance, depression, confusion, dementia, poor memory, and
soreness of the mouth or tongue.


Vitamin B12 is required by the
body to maintain healthy nerve cells and red blood cells and is also
needed to make DNA, the genetic material in all cells. B12 is one of
eight water soluble B vitamins all of which help the body convert
carbohydrates into glucose (sugar), which is a primary energy source
for the body. Vitamin B12 also works closely with vitamin B9 to
regulate the formation of red blood cells and to help iron function
better in the body.
