<<Disclaimer: Verify this information before applying it to your situation.>> Hi all! A while ago I asked some follow up ?s based on what I'd read in Dr Green's new book. Unfortunately it seems my questions were premature based on current state of research. One lister suggested I ask Dr Fasano directly but I've not heard back from him, which is understandable. Our GP also checked whether there is any lab in Canada currently testing for zonulin levels & she was told there is not. Guess we need to wait for the next breakthrough! Cheers.
