i would look into kefir, Chaga or kombucha.
You get a starter and grow it yourself. Kefir is what we grow. Kefir taste similar to yogurt. Grew up with with my mom growing kombucha that didn't have a good flavor. Chaga works in the same pathways as Niacin though I never had it.

I just said something similar Steve. Kefir and kombucha are fermented. There's plenty of stuff that's fermented off the shelf that can help the gut flora. Chaga or shilajit are also good suggestions. All health comes from the gut, but no one wants to talk about it.
