Vitamin B12 is essential to our metabolism of fats and carbohydrates and the synthesis of proteins. It is also essential for the transportation and storage of folate within the cells and for the conversion of it to its active form. B12 is also involved in the manufacturing of the myelin sheath, a fatty layer which insulates the nerves, and is essential in the formation of neurotransmitters. Blood formation and genetic material also require the presence and use of vitamin B12. Vitamin B12 supplementation can also be used to help treat cardiovascular disease and diabetic neuropathy.
