It especially involves DNA regulation and synthesis and energy production. The most structurally complicated vitamin, vitamin B12 is also the largest and contains the rare element cobalt. The basic creation of this vitamin in natural environments is achieved by bacteria and algae, but may be created in the human body in combination with other B vitamins.

Consult your physician if you think you may be experiencing side effects, deficiencies or allergies to B12. Side effects, allergies or toxicity seem most often to occur with the administration of supplements rather than food sources.
