Probiotic and gut biome research is all over the place.

It’s possible to find some studies showing correlations, but it’s harder to find successful replications of those studies.

Some probiotics have been shown to temporarily alter gut flora, but it usually reverts after the probiotic is stopped. Dietary and activity changes are generally good at improving the biome.

It doesn’t help that one of the commercial guy biome measuring companies basically turned out to be fraudulent a few years ago. Even some of the public efforts to measure correlations are suspect or bunk because they relied on these services.
