Do you have GI issues as well? I wonder if there could be something else going on in terms of absorption or blood loss.
My doctor had me take this supplement with my iron pills to help with absorption.
When I was anemic, they gave me 65mg of elemental iron 3x a day and I was taking so much it didn’t matter whether or not I took it with food. My doctor also had me take this supplement once a day and it helped a lot.
