Top 10 Foods Highest in Vitamin B12 (Cobalamin)

Vitamin B-12, or Cobalamin, is the largest and most complex vitamin currently known to man. A slight deficiency of vitamin B-12 can lead to anemia, fatigue, mania, 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, synthetic forms are widely available and added to many foods like cereals. Vitamin B12 can be consumed in large doses because excess is excreted by the body or stored in the liver for use when supplies are scarce.
