Vitamin B12 Deficiency
Vitamin B12 is very important in our bodies because of its role in the production of our red blood cells. Red
blood cells oxygenate our system so that we can effectively fight off all sorts of diseases.
They carry oxygen through our blood and then to our body tissues. Additionally, vitamin B12 works with B vitamin
folate to build our genetic material. In this respect, vitamin B12 deficiency will adversely affect all of these
processes resulting in a number of unhealthy conditions. Vitamin B12 (cobalamin) may lead to a wide range of
neuropsychiatric and hematologic disorders. Although these are serious illnesses, early detection and intervention
will always result in the reversal of the health condition.
When your body’s supply of vitamin B12 is lacking, you will not be able to produce the right amount of red blood
cells. A healthy amount of red blood cells are essential in supplying oxygen and nutrients (from the food you eat)
to your body’s cells and tissues. You must take a sufficient amount of it everyday. It is water-soluble and
absorbed readily by our digestive tract to be supplied wherever they are needed. Eating the right variety of food
such as poultry, fish, lean red meat, plus milk, cheese and yogurt would give you a fair dose of this substance.
You can also get some amounts from some fortified foods such as breakfast cereals and breads.
Who Most Susceptible To Vitamin B12 Deficiency?
There are basically two classes of
people who are most susceptible to vitamin B12 deficiency. The first are those who have illnesses or health
conditions where their bodies cannot absorb vitamin B12 from the food they eat. Those advanced in years are also
prone to this deficiency. Statistics obtained from CDC shows that out of 31 adults aged 51 years and above, one of
them will suffer from lack of vitamin B12. Those who are on strict vegetarian diets and are not eating foods that
are rich in vitamin B12 as well as babies born to vegetarian mothers are well at risk. Alcohol and drug abusers
also are very much at risk.

can cut your risk of being deficient in vitamin B12 by:

meats, fish and poultry are also good sources of vitamin B12. You can also eat more foods fortified with vitamin
B12 such as breakfast cereals.

vegetarian dieters, those with celiac disease or crohn disease, etc.
