Vitamin B12 comes from the Vitamin B family. It is required for the growth of new blood cells and the health of the nervous system. If you include eggs, dairy and red meats in your diet then your chances of a deficiency are low. However if you are on a vegan diet then your chances of being deficient are high. Deficiency of the vitamin can lead to anemia and if the deficiency is not taken care of then it can lead to stomach cancer.
Some of the symptoms of anemia include fatigue, breathlessness and infections; women may experience disruptive menstrual cycles. Deficiency in folic acid and iron can also cause anemia and hence one must speak with the doctor about the exact cause. If you are unable to get the required amount of vitamin B12 from your diet then you must take regular supplements orally or via injections.
Besides being important in the production of blood cells; vitamin B12 is also plays an important role to increase energy in the body. Studies have proved that the amount of vitamin B12 decreases with increase in age; hence one will notice energy levels depleting with age. This is also one of the reasons why you must increase the dosage of the vitamin after the age of 50. A healthy dose of the vitamin helps to increase cognitive abilities and heals neurological impairment.

The vitamin is also known to be a useful aid in increasing concentration and improving memory in addition to relieving irritability. Vitamin B12 is also known to increase appetite in children and hence it is important to make sure that they are getting the right amount of it.
