I heard only soil based probiotics make it to the gut. Why do your probiotics work if not soil based?Updated 6 months ago

We use probiotics called "spore formers" that are hardy and able to survive very harsh conditions, and thus make it to their pet's gut. Many competitors use probiotics that are dead long before the packaging is even opened. We stand behind our label claims and our high quality, and we do regularly testing to ensure this.
