These are the probiotics & enzymes that I currently take:
1) Kimiabiotics by Kimialogic (it is a product created by the former GI doctor that I saw)
2) Vegetarian Digestive Enzymes also by Kimialogic
3) Ultra Flora Acute Care by Metagenics
I take a similar product for digestive enzymes (DGT from theramedix), and do well with it.
If you have very strong SIBO, for probiotics only prescript assist, saccharomyces boulardii are recommended.
If you want to be on the safe side, you could start with these probiotics and with fibres, but except inulin+oligofructose (FODMAP´s) and raw PS.
Both probiotics are good choices, but not cheap, there are cheaper probiotics with larger quantities and more strains.
I also had SIBO-symptoms (potbelly, ruflux etc.), but with a mix of a ratio of 1/4 potato starch and 3/4 fibres, saccharomyces boulardii, prescript assist and a 10-strain-probiotic I had success, and I got better.
I read the whole thread 2 times, I copied the most important posts in word (if you interested, I can send it to you, but it´s also very long, as so many posts are important). I found, that I had benefit not only to know, what kind of fibres are possible, but there is so much knowledge about immunity and philosophy in general, that helped me very much.
I wish you much success with starting! jepps
