When the time comes to start 'trying' for a baby, it's important to be physically ready.  Here we're giving you the low-down on folic acid, an essential vitamin for a healthy baby. What is folic acid? Folic acid is one of the group B vitamin family. It is a water-soluble vitamin and is found in green vegetables. It's also present in fortified foods including cereals, milk and bread. What is the role of folic acid? Folic acid is required for the manufacture of nucleic acids - the genetic material of cells. It's vital for the development and proper function of the central nervous system. Folic acid has been proven to aid the closure of the spinal cord during the early development of a foetus which helps to prevent spina bifida, anencephaly and other neural tube defects. What is Spina Bifida? Spina Bifida is a birth defect of the back bone and the spinal chord. It is one of a group of birth defects called neural defects that affects the spine and brain. The neural tube is the embryonic structure that develops into the brain and spine.   How much folic acid should be taken? It is recommended that women of child-bearing age take 0.4 milligrams daily. When should folic acid be taken? Woman who are planning to become pregnant are recommended to take folic acid in supplement form for at least 12 weeks before they become pregnant. This ensures that the folic acid can build up in the system and be effective, as the baby's spinal cord closes very early in the pregnancy. For how long should women continue taking folic acid? It is recommended that folic acid is taken throughout the first 12 weeks of pregnancy. This article is brought to you by Clonfolic.
