Vitamin B12 is important for metabolism. It helps to make red blood cells. It is important for nerve cell function.
It is only available from fish, poultry, meat, or dairy sources. Supplements and enriched foods such as fortified cereals are available for vegetarians.
Deficiency can cause anemia (especially in vegetarians and the elderly) and nerve damage.
Important note: Excess of one B vitamin may cause deficiency of others.
