The organic food constitutes fats, carbohydrates, and proteins while the inorganic component constitutes vitamins and minerals .Vitamins are an essential part of human body and play important role in the proper functioning of various components of the body. Vitamins are further divided into water soluble and fat soluble. The B family of Vitamins constitutes the water soluble part; the B family itself is a large one and contains vitamins like B1, B2, B3, B5, B6 and B12.
Vitamin B12 is also known as coblamin, and the human body has large reserves of this type of vitamin inside it .The absorption of this vitamin is made possible through distil ileum; however the absorption depends on several factors, one of them is stomach, while the other is R binding factor. It is the only existent metabolite that contains cobalt. They are responsible for proper growth since they are cofactors in number of enzymes.
Importance of Vitamin B12:
Vitamin B12 helps in maturation of Deoxyribonucleic acid and is responsible for the proper working of both white blood cells and red blood cells. Mostly found in animal products, and are synthesized only by micro organisms. Very human body contains large reserve pool. It is primarily stored in the liver. It helps avoiding the heart diseases to large extent by keeping the blood level of amino acid homocysteine low. In elder age it helps preventing many diseases and problems (John.N.Hathcock, 2004).

Women, above 19
During pregnancy
Vitamin B12(ug/serving)
Beef, ground, extra lean,3oz
Reference: (Bobroff, 2008)
Screening method:
The deficiency can be determined through measurement of serum vitamin levels .a more detailed and slightly sensitive method of detecting vitamin B12 is the measurement of serum methylmalonic acid and homocysteine levels .Increase in the level of the mentioned can give idea about the deficiency of vitamin B12.Use of Schilling test detection is also part of screening method which helps providing information about blood level.
Vitamin B12 is an important constituent of the human body, and ensures the smooth working of the body in many aspects, its deficiency can have severe impact on the proper working of body, and it ensures a healthy and stable nervous system. This vitamin can be found in large variety of foods. Imbalance in the diet in terms of the vitamin deficiency can damage the human body directly, this vitamin can be termed as the power house to the proper working of human body, and hence its importance cannot be ignored .
