I think there are many different opinions but when I went to have my first child my Doctor was very big on simply eating a healthy diet. he didnt believe in taking extra vitmains and such unless you needed them. He did blood tests and told me that my levels in all things were perfect and not to worry about taking tablets of any kind. he would test me monthly during my pregnancy and said that I never needed anything. My baby was very healthy.
My 2nd pregnancy and a different Doctor and i was put on Iron tablets which were a nightmare. I became seriously constipated and ended up hemmoroids because of it. No amount of changing my diet helped with the constipation, heartburn and just plain feeling uncomfortable i felt.
Baby #3 and i refused to take Iron but i did take folate. My pregnancy was much better.
All my kids were/are helathy
