I was not prescribed a B complex vitamin but my mfm had me start folgard last summer before I got pregnant again. Folgard RX is the prescibed version of what I am taking and I think the daily values are similar to what you were prescribed. I know there are other brands as well. I have also been taking an LDA for the duration. Hope that sheds a little light on things. For me,so far so good.
