From those prior studies, red cabbage juice, manganese, zinc, probiotics, psyllium, fiber, broccoli (Indole-3-carbinol), and a low sugar diet can all help restore that gut lining.
If you are already getting enough of some of the items, consider pucking up the rest, along with the two amino acids, and see if you improve.
That is, “…picking up the rest…”
Certainly not if the source of the inflammation isn’t addressed.
Working on that myself, and skeptical that the mods will permit me to post the results when the time comes (history being a guideline).

Since Covid, I have been taking Zinc and B12 along with changing my coffee from having it with milk to having it with a bit of Boost. That took care of the long Covid. I believe the answer to long Covid is Magnesium and Potassium. As for gut leakage, I drink a bottle of Kambucha every week. Not sure what it does, but it seems to calm my stomach down.
