Interesting. I'm taking B-12 shots, and was on prescription D pills. The next time I see the doctor, I can ask about prescription iron--never even heard of it but it make sense. I do take the over-the-counter supplements when I remember to.

Oh, and I am also anemic from time to time--I've pretty much given up trying to donate blood--with my low weight, my low BP and sometimes anemia, I get deferred constantly.
