We try to solve things with pills, and certainly that is a very useful delivery mechanism for active medications. But there are a lot of fermented foods out there that have become unfamiliar in the Standard American Diet. The current science is still unclear about which bacteria combo is important, in which proportions, in which part of the GI system. BUT we do know gut flora is important. So my approach is to consume (in moderation but regularly) a variety of fermented foods that come from traditional cuisines. Yogurt with a wide variety of active cultures, Miso, Cheese from unpasteurised milk, Kimchi, etc. Also raw vegetables will likely have traces of microbes from the soil they were grown in, though I have no idea what role those play, if any.
