Ok, so how do you restore your lost colony, your inner rainforest with all it's diversity? First, probiotics that you buy won't do it. There is not one probiotic on the market that will implant or colonise the gi tract. These are mostly made up of bacteria that are produced by the dairy industry and they are not species that inhabit the gi tract. lactobacillus acidophilus, bifidobacterium bifidus L. themophius, salivarius and others like them may offer some people some short term benefit and they may taste good in yogurt, but don't count on them to cure you of anything. To make an analogy, it would be like trying to reforest the amazon rainforest after a clearcut with a sixpack of pansies. So how do we solve this dysbiosis? Not by any manufactured probiotic. They are the wrong species, the wrong strains produced by the food industry with a designation by the FDA as GRAS (generally regarded as safe). In order for a probiotic to work it must be a species of bacteria of human origin. And guess what folks, the probiotics industry, to my knowledge, has not developed one yet. The largest class of bacteria, that we most depend own, that predominates all other species of bacteria, are bacteroides. Ever seen Bacteroides offered in your probiotic blend? I didn't think so.
