In Australia it is recommended that if you are contemplating pregnancy you consider supplements such as iodine and folate. These should be started one month prior to conception. The dose of folate that you need will largely depend on your medical history and family history. We recommend you see your doctor 1-3 months prior to when you want to start trying to conceive to work out what your individual needs are. This is a good opportunity to also discuss healthy eating in pregnancy and what foods to avoid.
