spring valley wal-mart
I am ttc, and I bought an over the counter pre-natal vitamin at wal-mart(Spring Valley)?

It contains 800 mcg of folic acid. Is this too much, and would it be safe to switch to the prescription PNV once I conceive?
Spring valley is the brand of vitamin, not the location of wal-mart.

When you are trying to conceive, you should be taking 1 mg of Folic acid every day, (1000 mcg), and when you do conceive, it should be increase to 4 mg.
