Something worth a try. I looked it up and there's a L-Glutamine powder that you can get for very little to try it out. If you do try it, don't go for the body builder $30 canisters. Then you will be stuck with so much of it if it does not work. Yes, I am going broke trying to solve this as well.
Anyone else have success with the Glutamine? It makes sense-there's medical literature backing up that gut permeability is affected by this amino acid. It's also detoxing for the liver. Peace.
