Geritol takers...

I have been doing a little bit of research on Geritol, and even though it is a multivitamin, I am seeing that it's a benefit to TTC as well.  I just want to know who has had a good experience with Geritol and when is a good time to start it?? I am currently just doing the good'ol check my cervix and cm along with opk's.  So thought to throw in the Geritol in the mix.
