I think brand doesn't matter, there is many type of calcium likeI am now in my 5+month and I have never been prescribed calcium..wonder why...maybe my gynae feels that I am quite big boned, so should have lotsa calcium to spare..haha
Actually my gynae prescribed very little supplements for me. Only Folic and Fish Oil (only to be taken if I do not eat any fish).
Check pre-mummy here what brand calcium supplement is recommended for preggy? i'm in 7weeks and wanna take some from being now, it's needed?
