Why it's different
Most Cat Probiotics Never Reach the Gut
It's not about the biggest number on the label. It's about how much actually survives to do the job.

The science, simply
Built Around a Probiotic That Survives the Trip
Most standard probiotics are destroyed by stomach acid before they reach the intestines, so they can't support the gut the way they're meant to.
Vivobiotic® is built around Bacillus Coagulans, a spore-forming strain with a natural coating that survives stomach acid and reaches the gut alive. Paired with a 6-strain probiotic blend, prebiotic fiber and functional botanicals to support a balanced microbiome. It's not about the biggest CFU number. It's about how much survives to actually work.
