As edgyquant says, these pills are called probiotics, and they're readily available. The problem is that the gut biome is composed of 16 gajillion types of microbes, and understanding their individual & synergistic effects is nearly impossible currently. I do self-treat with probiotics periodically, but I see it as basically a leeching- or bloodletting-tier technique. See fecal matter transplantation - we're still in the dark ages here.
