Folic acid is the synthetic version of the vitamin folate, also known as vitamin B9.

Folate helps the body make healthy red blood cells and is found in certain foods.

Folic acid is used to:

· Treat or prevent folate deficiency anemia.

· Help your baby's brain, skull, and spinal cord develop properly in pregnancy, to avoid development problems (called neural tube defects) such as spina bifida

· It helps reduce the side effects of methotrexate, a medicine used to treat severe arthritis, Crohn's disease, and psoriasis.

Folic acid is available on prescription. It comes as tablets or as a liquid you swallow.

You can also buy lower-dose tablets from pharmacies and supermarkets.

Folic acid can also be combined with:

· ferrous fumarate and ferrous sulfate, to treat iron deficiency anemia

· other vitamins and minerals, as a multivitamin and mineral supplement
