The 12 b vitamin
is one of the b vitamins that are essential to maintain a healthy body.
Otherwise known as Cobalamin, the 12b vitamin is needed for the processes to
convert the carbohydrates, fats and proteins from food into energy. 12 b also,
more importantly, helps keep the red blood cells healthy and therefore prevent
heart disease as well as keeping the immune system functioning at its maximum
level. In addition, 12 b is used to create the protective covering of all nerve
cells in the body.
The most
important function of 12 b is to form healthy red blood cells. However, all
cells need 12 b to keep them healthy. It is the white blood cells, amongst
others, that need 12 b to help ensure that the immune system functioning
properly. All of the nerve cells in the body also need 12 b to form their
protective fatty layer. This is essential for all of the nerves but is
especially so for those in the brain. If there is not sufficient 12 b to create
this protective layer then the brain will not be functioning properly.
Interestingly,
the amount of 12 b that the body needs is relatively small but is needed on a
regular basis. However, 12 b on its own is not enough as the body cannot absorb
it easily. To help the body absorb 12 b the stomach produces intrinsic factor
which enables more of the 12 b to be absorbed. 12 b is only found in animal
foods such as liver, eggs, fish and meat but most people consume far more than
their recommended daily amount of 12 b. This is not a problem as the body can
only absorb about half of the 12 b that is consumed. It is also worth noting
that the body can recycle the 12 b which cuts down on the impact of a 12 b
deficiency. However, strict vegetarians or vegans are likely to require 12 b
supplements if they do not eat any animal products that contain 12 b.
If the body does
not have enough 12 b then anaemia is the most obvious symptom. Obviously, this
is due to the fact that there is not enough 12 b to make healthy red blood
cells. Anaemia can also be caused by the body not creating enough intrinsic
factor to help absorb the 12 b that is available in the food consumed. The body
tends to makes less intrinsic factor once a person reaches 50 and this will
lead to less 12 b being absorbed and supplements of 12 b may be required. Kids
are also at risk from anaemia because they may not eat the food that contain 12
b. Pregnant women need more 12 b because the baby is absorbing 12 b during the
pregnancy to grow properly.
