Vitamin B12, also called cobalamin, is a water-soluble vitamin. Water-soluble vitamins are stored in the body in limited amounts and are excreted through the urine. Therefore, it is a good idea to have them in your daily diet. Vitamin B12, the most complex of the vitamins, contains the metal cobalt in its structure.
Vitamin B12’s functions include the following:
- Assisting in the production of neurotransmitters, which are chemicals that regulate sleep, pain, and mood
- Enabling proper DNA replication
- Helping catalyze the reaction that produces succinyl-CoA, a chemical required for the synthesis of hemoglobin
- Making red blood cells and preventing anemia
