If you want to go a bit off the traditional path, you can look into BPC-157 which is a peptide that was designed to help heal the gut. Nowadays it's mostly used by athletes and anti-aging people to help heal soft tissue damage, but the original purpose was to heal your gut.
If you're in the US, you can probably find an anti-aging clinic with a doctor that you could ask about it.
I went way off the beaten path and got into peptides by way of kambo. It's an indigenous medicine that's very controversial with very little controlled scientific research, but it actually made a dramatic difference for me. Might look for into peptide injections, though it's harder to find them in my home country (Hungary).
