The simple answer is the amino acid powder which your body/immune system cannot react to because they are pre digested and your immune system cannot react to whole proteins. That prevents many of the problems. I have been using amino acids myself since earlier last year as my digestive system is so hyper permeable. The infection which causes the problems will not be fixed by doing this. They are highly resistant and take a lot to destroy. Something which I am planning on doing ASAP as soon as I can get a few other things completed. Things keep getting in the way which is holding it all up.
