The Importance of the B12 vitamin

The B12 vitamin is among the b vitamins that are necessary 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. B12 also, more to the point, helps keep the red blood cells healthy and for that reason prevent heart disease as well as keeping the immune system functioning at its maximum level. In addition, B12 is used to generate the protective covering of all nerve cells in the body.

The most crucial function of B12 is to form healthy red blood cells. However, all cells need B12 to keep them healthy. It's the white blood cells, amongst others, which need B12 to help ensure that the immune system functioning properly. All of the nerve cells in the body also need B12 to form their protective fatty layer. This is required for all of the nerves but is particularly so for all those in the brain. If there is not sufficient B12 to produce this protective layer then the brain will not be working correctly.

Interestingly, the amount of B12 that the body needs is relatively small but is needed on a regular basis. However, B12 on its own is not enough as the body cannot absorb it easily. To aid the body absorb B12 the stomach produces intrinsic factor which enables more of the B12 to be absorbed. B12 is only present in animal foods such as liver, eggs, fish and meat but most people consume way over their recommended daily amount of B12. This is not a problem as the body can only absorb about 50 % of the B12 that is consumed. It is also worth noting that the body can recycle the B12 which decreases the impact of a B12 deficiency. However, strict vegetarians or vegans will certainly require B12 supplements if they do not eat any animal products that contain B12.

If the body doesn't have enough B12 then anaemia is the most obvious symptom. Obviously, this is because of the fact that there is insufficient B12 to make healthy red blood cells. Anaemia can even be caused by the body not creating enough intrinsic factor to help absorb the B12 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 B12 being absorbed and supplements of B12 may be required. Kids are also at risk from anaemia simply because they may not consume the food that contain B12. Women that are pregnant need more B12 considering that the baby is absorbing B12 throughout the pregnancy to develop properly.
