If you answered yes to 6 or more of the questions above, you should have your B12 levels tested to determine if you have a Vitamin B12 deficiency, and assess the severity of the deficiency.
The impact of a Vitamin B12 deficiency on health is significant. Vitamin B12 deficiency leads to decreased production of red blood cells in the blood. Healthy amounts of red blood cells are required for the delivery of oxygen to all the cells and tissues in the body. Deficiency can affect normal growth and development, production and health of nerves, skin, hair, genes and normal metabolism.

Folate deficiency can also be associated with Vitamin B12 deficiency and can cause similar symptoms. Folate deficiency is less common due to the fortification of many foods with folate. However, folate deficiency is associated with neural tube defects and all women of childbearing age should be assessed for potential folate deficiency and take a supplement if indicated.
