Hello, all- I have been experimenting with different strains of probiotics. I seem to have some sort of dysbiosis that is not apparent on my GI Effects panel. Overall, it suggests that I have high levels of almost all of the bacteria types, except Lactobacillus and Bifidobacterium (which are at normal levels). I have a long history of antibiotic usage, as I had ear and sinus infections frequently as a child, so I am sure this led some of the groundwork for the dysbiosis. I know for sure that I have problems with D-Lactate producing probiotics (I get weird, systemic issues) and Lactobacilli in general (tend to worsen bloating). I am thinking of using bifidobacterium infantis 35624 to see if it helps with my symptoms of bloating, sluggish bowel movements, etc. I was wondering if anybody knows if there is value to using Bifidobacteria probiotics to rebalance the flora, even if the numbers on the stool test are already adequate. Anybody with experience or knowledge on this matter? *Also note: I carry a heterozygous mutation in all of the FUT2 genes that are looked for, which apparently causes issues with maintaining bifidobacteria. I have read the research and understand that the tangible manifestations are at times ambiguous at best.
