So, iron can actually make your gut worse which is a problem. If you can figure out how to not *lose* iron that might make you not deficient, it worked for me and my issue was periods

I got Infusions

Complete agree that iron can mess up the gut. I was taking it in Res for my anemia and when I was feeling really bloated and unable to eat and when the doctor finally looked at me and my stomach she told me to stop taking them immediately. I still haven't found another solution yet, but it was pretty excruciating for a couple weeks

Another thing that helped me was researching things that help me absorb iron better or that inhibit iron absorption. For example, if you're eating an iron rich food it's good to pair it with something high in vitamin c and not to have dairy or tea with it. There's lots of articles out there about that kind of stuff.
