When do you start prenatal pills?

It's best to take them before you conceive. I wish all women that may become pregnant take them, my cousin had a baby with spina bifida. She could have prevented that with folic acid. Prenatal vitamins are not that expensive, you can buy them at health food stores for the same price as a regular multivitamin.

I think you should start taking the folic acid before you start trying to conceive, i only say this coz the initial stages are the most important. You don't wanna wait until you actually find out you're pregnant, you may have already missed however many weeks where it was needed - i was already 5 1/2 weeks pregnant when i found out we were having a baby so i could have been taking it much earlier than when i started. Definitely just got to a health food store or your local pharmacy & ask for folic acid, it's not an expensive vitimin at all & have your wife start taking them before you start trying to get pregnant. You could also try a multi vitimin which not only includes folic acid, but also many of other necessary vitimins which will do the trick as well :) I wouldn't bother taking the prescription in, just buy everything over the counter and try asking your pharmacist what they recommend - mine was SUPER helpful coz she was a new Mum herself so she knew which things would be most beneficial! Good luck with conceiving & i hope everything goes well!

Depends on what prenatal pills are, if you mean like in example folic acid from what I have learned it is best to start taking that 6 weeks before you even get pregnant. This is the most common supplement taken during pregnancy here.
