Q.What is Vitamin B12 used for in our body?
A.Vitamin B12 covers a variety of similar compounds called cobalamins. They are involved in DNA synthesis so deficiencies lead to insufficient DNA synthesis and cell maturation – particularly red blood cells. This is why vitamin B12 deficiencies cause anaemia (megaloblastic anaemia). The nuclei of the erythroblasts (‘parent’ cells of red blood cells) take longer to mature but the cytoplasm continues to grow so the cells produced are disproportional and larger than normal red blood cells. B12 deficiencies can also affect other rapidly growing cells in the body such as cells lining the gastrointestinal tract which can lead to gastroenteritis and related problems.
