Vitamin B12 is a water-soluble vitamin which helps in maintaining the functioning of the nervous system and the metabolic processes. They are also essential for DNA synthesis. Vitamin B-12 affects the development of the red blood cells, the nerve cells and the myelination (covering) of nerve cells.
Since animal food is our only source of Vitamin B-12, its deficiency is quite common these days. Children who follow vegan diets, adults who find it difficult to absorb Vitamin B-12 and pregnant women who suffer from hemorrhage or intestinal disorders are more prone to vitamin B-12 deficiency.
Fatigue, weakness in muscles, shortness of breath, dizziness, numbness, heart palpitations, bleeding from gums, sore mouth, nausea, and diarrhea are some common symptoms of vitamin B-12 deficiency. A vitamin B-12 deficiency can lead to anemia, resulting in memory loss, confusion, and dementia.
