Is it ok to take a prenatal and a multi vitamin at the same time?

If you are...... Pregnant, vitamin a is toxic to developing embryos in high doses. Prenatal vitamins do not exceed that dosage. They also have extra Folic Acid an often extra iron. Some also are including dha and lutein for your baby's developing eyes and brain. I would tell my own patients to take only the pnv. If not pregnant, taking 2 vitamins can give you toxic doses of vitamins a, d, e & k.
Why? Are you pregnant? The prenatal vitamin should be enough, if you are pregnant. If you are not pregnant, one should be enough.
