I'd suggested seeing your GP to ask what is enough. When DH and I decided to start TTC, we went to see our GP and she ran some blood tests on me. I had been taking Elevit but the results showed I have low iron levels, so she took me off Elevit and put me onto FeFol.

Even though Elevit has iron in it, she said I need to take a supplement more concentrated on raising iron levels.

I will have a test in three months (now two months) to see how my iron levels are and if they have gone up, I'll go back on Elevit.

The point of all this is that without seeing my GP, I wouldn't have known my iron levels were low.

Also, prenancy-specific multivitamins contain other things that are important, like Vitamin A, but not too much, which can harm the baby.
