I've taken both of these. I used Blackmores while TTC then switched to Elevit while on IVF and during pg because I have problems with iron deficiency and it served me well right up until the last two months of pg.

I think if have another baby, I will do the same the next time. Any sort of pg multi is good though ... good insurance for those times when you might be feeling a bit off your food. At least you know you are getting a regular intake of the things you need.
