I posted a similar thread a little while ago, I took Blackmores last pregnancy but combined with morning sickness found it hard to swallow them as they are absolutely HUGE and has a foul smell and taste.
We are TTC #2 soon and have started taking Elevit and have lots of great feedback from other girls here who have used them. For one they are a bit smaller than the Blackmores and have hardly any smell or taste which is great as just thinking of the Blackmores ones makes me feel sick now so I didnt like the idea of trying to keep them down again if I do get morning sickness next time.
Also they have as many vitamins and trace minerals as the Blackmores, actually I think they even have a couple more when I compared them to each other.
Hope this helps.
