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.

What's Inside

Active ingredients measured per ml. Every ingredient has a reason to be there.

L. acidophilus, L. rhamnosus, B. longum, L. plantarum, B. breve and L. casei for broad gut support.

Chicory Root Inulin

Natural prebiotic fiber that feeds the probiotic strains.

Sodium Copper Chlorophyllin

FAQ

Common Questions

Everything you need to know before trying Vivobiotic.

How much do I give my cat?
One dropper a day, dosed by weight: ⅓ dropper (0.33 ml) up to 5 lbs, ⅔ dropper (0.66 ml) for 6–10 lbs, 1 dropper (1.0 ml) for 11–15 lbs, 1⅓ droppers (1.33 ml) for 16–20 lbs. In the mouth or mixed into food, once daily.
How long does one bottle last?
A 30 ml bottle lasts about 1–2 months depending on your cat's size.
Isn't the CFU count lower than other brands?
On paper, yes, but most of a high CFU count is destroyed by stomach acid before it reaches the gut. Vivobiotic uses spore-forming Bacillus Coagulans built to survive that trip. Survivability matters more than the number on the label.
How should I store it?
Keep cool and dry before opening. Refrigerate after opening and use within 6 months.
Will my cat actually take it?
It's tasteless and odorless. Mix the dropper into wet or dry food and most cats won't notice. Works even with picky eaters.
Is it safe for my cat?
Formulated for cats of all ages and breeds with natural ingredients. Not for use in immature, pregnant or lactating animals. If your cat has a medical condition or takes medication, check with your vet first.
Money-back guarantee?
Yes, 60 days, no questions asked. Return the bottles (even empty) for a full refund.
