The timing does not make a difference. However iron and calcium pills cannot be taken together. Also try and ensure that you do not take iron pills with milk or milk products to avoid taking calcium and iron together.

It doesnt create any problem if they are pregnancy related supplements like calcium and iron tabs..But if you have any other tablets pls do check with ur doctor <u>once</u>

No it doesn't

No.. it's won't create any problems if you are taking as usual calcium, iron or folic acid tablets. If any other...please with your gyno once.
