The human body requires the basic nutrients for its normal functioning which are carbohydrates, fats and proteins. However, there are certain vital vitamins and minerals too, that are equally important because these help in maintaining the proper health of a human body in various ways. One such vitamin is Vitamin B complex of which, there is a crucial vitamin known as Vitamin B12 or scientifically called as Cobalamin.

Functions of Vitamin B12: Vitamin B12 plays a major role by controlling several factors of the human body. These are necessary for the body to run well and stay healthy. Some of the key functions of Vitamin B12 are listed below:

1. It is responsible for the conversion of raw carbohydrate matter that enters into the body in the form of food into glucose that is the driving energy for the body. Therefore, in a way it helps to keep the continuity of energy production in the human body and its deficiency, therefore, can lead to fatigue or weakness.
2. Every single nature of human cells is related to the DNA and RNA that define the genetics and hereditary factors of a human body. Vitamin B12 assists in the creation of this DNA and RNA.
3. Vitamin B12 also helps in the production of nerve cells in the human body by maintaining the covering of the nerve cells or neurones known as the myelin sheaths. This helps to free the body from the reach of toxins and free radicals that can be very harmful to the human body. Hence, any shortage of Vitamin B12 can damage the nerve cells in a considerable manner.
4. The bones of the human body need Vitamin B12 as well and any deficiency of Vitamin B12 can cause osteoporosis and other bone issues.
5. Vitamin B12 in association with another vitamin known as Vitamin B9 (folate or folic acid) helps in the manufacture of red blood cells that help in impressive iron functioning, which is the main oxygen carrier of the human blood. Quite evidently, its deficiency can lead to shortness of breath and other breathing disorders.
6. Even heart requires an adequate amount of Vitamin B12 along with Vitamin B6 and Vitamin B9 so that appropriate levels of amino acid named homocysteine are produced that is a deciding factor in heart diseases.
7. Vitamin B12 is an essential component affecting the brain health too, and any deficiency of Vitamin B12 can often lead to various brain disorders such as Alzheimer’s disease and the like.

In fact, Vitamin B12 has also been found to regulate mood and emotions of humans. Above all, Vitamin B12 is vital for keeping an individual happy and healthy by revitalising the body cells and making him or her feel youthful and vibrant all the time.
