Just an FYI that our physicians have also always recommended using natural probiotics like organic kefir and pure, plain yoghurt, sauerkraut etc - this includes using them as gut biome restoratives when taking antibiotics. We were also told they should be used approx 2 hours after the antibiotic dose.

One of my family members deals with Crohn's Disease, and has from the outset been told to avoid those probiotic supplements, which seem to irritate his GIT intensely, and stick with the kefir, yoghurt and fermented foods, which he tolerates well.
