I'm always happy to read this kind of articles. I have a history with C. ulcerosa myself (now under control) and since it begun my gut just hasn't been the same. I am pretty sure my microbiota was left in a very bad shape after some hard periods, and since then I have tried to bring it back to balance... but it seems a hard task. I haven't tried probiotic supplements, like described in the article, but just tried to include probiotic-rich food in my diet, like yogurt and sauerkraut, and also prebiotics like bananas and honey. So it would be just great to get exactly the combination of probiotics-supplements that one needs, based on this kind of uBiome test, and then just wait until you have a balanced microbiota again. But for what the article describes, we would have to wait a bit until the real effects of each particular probiotics-combination are understood.
