i was taking blackmores last time and had to take iron aswell as i ended up anemic, this time i had the symptoms i had before but the teast said i was not anemic, my GP advised me to take elevit as it had highter iron than blackmores and it seems to be working. they seem to be pretty similar just the elevit has higher levels of some things. I guess you could allways take other things separatley if you think its lacking
