Do you take Iron Supplements while on Iron Infusions?

I have infusions about every six months.

I have tried every kind of oral iron, iron patches (helps a bit), and Proferrin (heme iron) -- I simply don't absorb iron. I have taken iron correctly -- with C and away from dairy and coffee -- in the morning, at night -- in the middle of the night ...

I just don't absorb it. I wish I did. Infusions are horribly expensive.

I still take Proferrin and use a patch to try to stretch out the time between infusions -- but ultimately, it really doesn't help me.
