What is Vitamin B12 for?
Vitamin B12 is necessary for processing carbohydrates, proteins and fats and to help make all of the blood cells in our bodies. Vitamin B12 is also required for maintenance of our nerve sheaths. Vitamin B12 acts as a coenzyme in the synthesis and repair of DNA.
Vitamin B12 cannot be absorbed or used by the body until it is combined with a mucoprotein made in the stomach called an intrinsic factor. Once the B12 becomes bound to the intrinsic factor, it is able to pass into the small intestine to be absorbed and used by the body. Vitamin B12 deficiency is sometimes seen in strict vegetarians who do not take vitamin supplements, and those who have an inability to absorb the vitamin (usually from a failure to produce intrinsic factor). Although enough B12 is stored in the liver to sustain a person for many years, a deficiency will cause a disorder known as pernicious anaemia. Pernicious anaemia causes weakness, numbness of the extremities, pallor, fever and other symptoms. Mouth irritation and brain damage are also common consequences of B12 deficiency. However, these very serious effects can be reversed by vitamin B12 shots.
