I tend to agree with AnnieBrooke. Unless you have a certain vitamin or iron deficiency, it probably won't help much. I think it's more of an old wives' tale.
You don't have to take fertility drugs or Geritol to get pregnant. If you are having problems getting pregnant, Geritol probably won't help you at all, it is just an iron-heavy vitamin.
You can take geritol without fertility meds. Geritol is basically just a vitamin supplement that some people claim helps women get pregnant. Whether that is true or not is another story. I tried it for a couple of cycles when I was trying to conceive and it didn't work for me...but who knows? Good luck to you!
