yes it must be mcg..i think they only offer in 1 mg at the most, and anything other than that would need a perscription i would think..i dunno..like i said 0.4 mg is the recommended..that mean 400mcg..1000mcg ->1 mg
You don't need a prescription for folic acid, like someone said, you can't overdose. I take 4 mg because of some meds I take that can cause problems. Most OBs will tell you to take 1mg during pregnancy. But in all actuality, once you decide to start trying you should start taking it cause the things it help prevent usually occur before you know you are pregnant!
I take what is in my prenatal as well as one supplement per day. I don't know what the dosage is in my pill though...its in the bathroom and I'm not getting up to check right now! LOL
I started taking 5mg of folic acid a year before my husband and I started trying for our baby. I have epilepsy and my specialist nurse said it would help to get it into my system early. I'll continue to take the 5mg up until the day I deliver the baby. There's no harm in taking it and you can't really take too much of it either.
