Purina Pro Plan Veterinary Supplements FortiFlora Feline Probiotic Supplement is the #1 Veterinarian recommended probiotic supplement for cats and dogs. The first and most proven source of Enterococcus faecium, the probiotic strain most beneficial to pets. Promotes GI and immune health

For any pet products that contain probiotics, the odds are that the probiotic strain of choice (or at least one of them) is Enterococcus (E.) faecium. It is by far the most established and researched strain of probiotic in dogs (and more recently in cats too).

FortiFlora is the original and most proven probiotic supplement for pets that contain E. faecium, the only probiotic strain included.

That’s still only part of the story. Thanks to the R&D might of the parent company, FortiFlora also contains a proprietary strain of E. faecium that no other companies have access to. It comes in the form of freeze-dried powder guaranteed to contain live cultures of said E. faecium strain that are certain to form colonies in your pet’s gut.

FortiFlora is easy to feed too. Just add the contents of the sachet to your pet’s food. The liver-flavored powder is tasty enough that many dogs and cats will eat it as is.
