What milk do you mummies drink for pregnancy and breastfeeding(does it really have milk?) ?

I had Ammum Maternity towards the last trimester because I was given it as a sample and it was the only thing I was okay with having at that time - but I didn't continue after because it was really heaty and my appetite changed. I'll say that they aren't necessary, but may be good if your gynae recommends it for you because of health concerns :)
