I take elevit, same as I took before, during, and after my two pregnancies. It contains 800mcg.
I just checked - my prenatal has 800mcg and I also take an extra 800mcg when I remember.
For pregnancy I think 400mcg is recommended at the minimum. You actually end up getting more from your diet since all enriched bread products have folic acid in them. You can take a ton of folic acid with no negative side effects. My first RE said ladies who have had a child with spina bifida take 4mg or more will no bad effects. It is pretty safe. I think the 400mg was a typo though or mislabel???
My Dr. prescribed 5 mg plus I take a multivitamin with 0.4 mg, so I guess all together I'm taking 5.4 mg. I think 400 mg is way too high. Perhaps it's supposed to be 4 mg??
1000 mcg should be fine I think if it is in your prescription prenatals. But I have never seen any site mentioning 400 mg. I am going for IVF this month and I am taking 800 mcg.
I have a prescription for it. The bottle doesn't same the mg though. Sorry. :-(
My doctor told me 400 mcg. Then incrase it to 800 after pregnancy.
