Sorry, I don't know anything about polysacharides not being ok for bacterial overgrowth or the autoimmune issues. I'm using it to avoid getting sick since my mucous membranes are so weak. It has worked well for that purpose for me. Hopefully I'm not causing more harm than good for my situation but preventing getting colds and flu is worth a lot to me.
I have been cleansing for a very long time and have had a very leaky gut in the past after being put on Antibiotics over and over again for sinus infections. But I have not taken Antibiotics for the last 9 years since I started doing natural things instead. I think the main thing I am fighting now is H. Pylori and that is what is constantly destroying my gut lining. I just started back on Mastic Gum again. I just learned recently that the probiotic Culturelle is one of the best ones for fighting it. I always take one per day but I'm going to start also opening up the capsule to get it around my mouth and throat where I believe the H Pylori continues to grow. (I can easily get canker sores in my throat). I've read that it's so hard to get rid of because if it's in your throat you can keep re-infecting yourself. I take a ton of other probiotics too but when you are dealing with H Pylori it seems like many of the standard rules for candida cleansing change...for example, the best fruit for my stomach is a banana...very soothing and calming. These digestion issues are probably what keeps my body in adrenal fatigue, although I have a ton of energy compared to most others out here.
