Vitamin B-12, or Cobalamin, is the largest and most complex vitamin currently known to man. With just a slight deficiency of vitamin B-12 can lead to anaemia, fatigue, and depression, while a long term deficiency can cause permanent damage to the brain and central nervous system.
Vitamin B12 can only be manufactured by bacteria and can only be found naturally in animal products, however, there is a wide synthetic variety available and added to many foods like cereals.
