Your gut requires more than enzymes - it also requires a healthy population of gut bacteria and other micro organisms. If you want to heal your gut you need to cultivate that - think about probiotics you can tolerate, drink Kefir if you can tolerate that, eat more fermented foods, or at least take them in capsule form and don't keep killing them with antibiotics.

I found this book very useful
