This latter feature makes Folic Acid of particular importance to women contemplating pregnancy. The UK Government's Chief Medical Officer advises that all women should take a 400u.g. Folic Acid supplement from the start of trying to conceive through to the twelfth week of pregnancy in order to prevent birth defects such as Spina Bifida. Suitable for vegans.
