I'm sorry I don't know, but I too would research it. Good luck to you.
The company that sells this product should be able to tell you what the active ingredients are and what amount of vitamins and minerals are contained in each supplement. The definition of "supplement" is to be combined with another source. You need to make sure the product has the min required recommendations for folic acid etc. I am always concerned when one product can be used for all age groups and conditions. There is a reason why different age groups and conditions require different amounts of calcium, iron, folic acid etc.
I would think you could take this product and a prenatal vitamin together.
