I am determined to find an answer. I shall keep looking. I've contacted several organizations and will be getting in touch with Dr. Alessio Fasano's office on monday to see if they know of anything. I know about his medication for blocking the effects of zonulin but I'm not about to go on medication for the rest of my life. I need something that can be taken on an as-needed basis when accidental gluten exposure occures.
zonulin is still in clinical trials, i think. it's being tested as a preventative, anyway, so you would already have had to take it prior to getting glutened.
