I also had to start taking iron and vit C also probiotics and Vit D not sure if this might help.

I don't know if this helps, but my oncologist also put me on iron supplement. He told me to take vitamin c with my iron pill cause my body doesn't absorb iron well.

I've had iron infusions a few times with no problem.

I've gotten iron infusions twice and had no side effects.

Sable, I am a Nurse and I have seen Myeloma patients get IV iron. They usually had Anemia really bad. Iron does mess up the GI tract when taken orally. After my Femur Surgery, I had lost a lot of blood so they gave me Iron orally and I could only tolerate it for 2 days and asked to go off of it, my tummy couldn’t handle it. Have a good night!
