As Amanda said the usual culprit causing constipation is the
iron,but even with it in the multi and the
liquid form I have had
no issues. I am not taking any fibre either. I bought everything at the health food store. I have had no problem with constipation, in fact I am still very regular with this pregnancy. check out www. sisu. com without the spaces and go to products then womens health and it will give you the lowdown as well as where to buy.
Hope this helps!
