Why does a lack of folic acid cause anaemia?
Red blood cells are made in the bone marrow and circulate in the blood. They only have a life expectancy of about four months. The body needs iron, vitamin B12 and folic acid (one of the B group of vitamins) to produce more red blood cells. If there is a lack of one or more of these nutrients, anaemia will develop. A person who lacks folic acid may experience intestinal problems as well as the usual symptoms of anaemia.
