Excellent – I was using Elevit prior to this. After seeing my OB, he suggested that I switch to Blackmores instead as this has iodine and a few more extra goodies that Elevit doesn't have. With Elevit, I have had a problem with constipation. This went away as soon as I switched to Blackmores. I have used Blackmores until after giving birth well into my breastfeeding days. This has been highly recommended by all of the people in the medical profession that I have seen (OB, GP, midwives and nurses). Cheaper than Elevit and it contains iodine (which elevit that does not have) which our unborn babies need for brain development none really. some people have complained that the tablets are bigger. However, their smooth design means they go down easily.
