Several conditions either increase the need for folate or increase the risk of folic acid deficiency. They include those being treated by anti-convulsant medication, patients on kidney dialysis, or those with conditions such as liver disease, malabsorption or certain types of anaemia.
You can get folic acid tablets from pharmacies, large supermarkets, health food stores and on prescription. Dietary sources of folic acid include green leafy vegetables, breakfast cereals and bread. Check with your doctor first if you are receiving treatment for any condition (such as epilepsy) that may not be compatible with folic acid supplementation.
