Common questions
What does UK guidance say to take before conception?
Folic acid 400 micrograms a day from before conception until twelve weeks, and vitamin D daily. Some people are advised a higher folate dose by their GP.
Is methylfolate the same as folic acid?
It is the form found in circulation and it meets the folate need; the UK guidance figure refers to folic acid, and your GP or midwife can advise which suits you.
When should we see a GP?
After a year of trying, or six months if you are over 36, or sooner if you have a known condition.
