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.

Vitamin B complex is a water soluble vitamin. Even if you take excess of it, it will be washed out of your body. B6 and B12 are types of B vitamins which are required for carrying out various reactions in our body. They act as coenzymes for different enzymes and hence affect different reactions in our body.
