Folic acid plays a role in the production of genetic material (DNA and RNA), and is required for cellular division. Foetal cells undergo constant cell division, so women require increased levels of folate during pregnancy. Inadequate intake of folic acid may interfere with the development of babys nervous system. It is recommended that women take folic acid supplements for at least a month prior to conception, as this nutrient is vital for the development of babys nervous system, and it is critical that maternal levels are adequate during the very early stages of pregnancy. If you are trying to conceive, consider taking Blackmores Conceive Well Gold, which supplies folic acid as well as other nutrients needed in preparation for conception and pregnancy, including iodine and the essential fatty acid DHA. Once pregnant, consider switching to Blackmores Pregnancy & Breast-Feeding Gold, a premium, comprehensive formulation containing vitamins, minerals and essential fatty acids beneficial for both mother and baby.
