Yes, I agree with that. If you are missing some mineral your body may take up some other metal as a replacement.

But I think that it is good to get your deficiencies corrected before going through chelation therapy. Chelation therapy may make some deficiencies worse because you lose some of the needed minerals in the process of getting rid of the unwanted metals.

I am surprised that your doctor is doing the chelation with you at this stage. Do you understand his logic for doing chelation before getting your nutrtional status completely corrrected?
