Vitamin B12

What is vitamin B12?

Vitamin B12 is very important for overall wellness: it helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA and aid in growth and development – especially in children. It is found primarily in meat, eggs and dairy products, whereas plants do not contain vitamin B12. Although the minimum requirement for vitamin B12 is quite small, a deficiency can be a very serious problem.

When is a deficiency likely to occur?

Vitamin B12 deficiency may occur as a result of an inability to absorb B12 from food. It can also occur in individuals that exclude animal foods from their diets. Generally, most individuals who develop a deficiency have an underlying stomach or intestinal disorder that limits the absorption of vitamin B12. A deficiency will result in anemia, and if prolonged, can lead to nerve degeneration and irreversible neurological damage. Severe Deficiency can also cause dementia and is a risk factor for cardiovascular disease. Early detection and treatment (usually with vitamin B12 injections) can reverse symptoms of deficiency. Always consult your physician for treatment.
