What is Vitamin B12?

Vitamin B12 is an essential vitamin that is water soluble and can be found only in food from animal origin. It should be administered only with food or by using products that contain B12. This vitamin is a co factor of two important enzymes necessary for anabolic and catabolic processes in the body and has key role in the synthesis of DNA, lipids and proteins as well as in the cell dividing and formation of erythrocytes.

 

This vitamin is also necessary for maintenance of the normal level of homocysteine in the blood, and with that of the structure and function of the nerve system particularly for maintaining the cognitive functions (concentration, studying, memory, reasoning). It decreases the risk of the following conditions while aging – Alzheimer’s, Parkin’s as well as dementia. The normal level of the homocysteine is connected with decreased risk od cardio vascular and neurovascular illnesses, kidney malfunction as well as possible decrease of the risk from cancer.

 

In the recent years, attention is diverted towards its usage as immunomodulator of the cellular immunity i.e. increase of the number of CD8+ or NK cells that are important for cancer cell destruction.

 

In general, the Vitamin B12 has role in the growth and maintenance of the overall health in all life cycles.

 

The low level of Vitamin B12 in pregnant women is connected with increased risk of defects of the neural tube. Certain population groups with specific lifestyle (vegans or vegetarians) are exposed to the risk of lack of Vitamin B12.

 

At 10-30$ of the older population as well as people with specific illnesses there is decreased absorption of Vitamin B12. For these population group it is recommended to add B12 supplements for better overall health.

 

Newest studies show certain positive effects from using Vitamin B 12 when SARS-CoV infections occur. The level of Vitamin B12 is connected with the level of symptoms of SARS-CoV infection, through the following examined mechanisms: decrease of oxidative stress, improvement of circulation (with decrease of the level of homocysteine that distorts the microcirculation of the cardio vascular system, the nerve system as well as kidneys) and with its anti-inflammatory usage.
