      About Saccharomyces boulardii

      S. boulardii is a special probiotic that’s a strain of yeast, not bacteria. Studies have shown that S. boulardii is safe and effective for dogs and that it can prevent and reduce diarrhea from multiple causes. It has anti-inflammatory properties. As a probiotic, it is especially helpful for regrowing gut microbe populations that have become imbalanced and for promoting healthy skin.

      And unlike bacterial probiotics, S. boulardii isn’t affected by antibiotics, so it can also be used during antibiotic treatment to help with the digestive side effects that antibiotics often cause. Studies have shown that when S. boulardii is given along with an antibiotic, dogs are much less likely to develop diarrhea during or after the course of medication.

      S. boulardii is also resilient to stomach acid, so when it reaches the intestines, it’s still intact and alive, while many bacterial probiotics die in the stomach and never make it to the gut. Once in the gut, S. boulardiiprovides food for beneficial microbes, supporting a healthy, diverse microbiome.

      About Fructooligosaccharides (FOS)

      Fructooligosaccharides (FOS) are tiny, soluble fibers. The raw material from which the FOS in our S. boulardii + FOS is produced is Non-GMO beet sugar*. These particular fibers are prebiotic, meaning that they are the preferred food of beneficial microbes like the ones in your pet’s gut. Making sure all the beneficial members of the gut microbiome get enough of the right food is crucial not just for healthy digestion but also for a strong immune system, healthy skin, and even a happy mood. Studies in dogs have shown that supplementation with FOS improves both gut health and immune functions.


      The 30g jar contains a 0.6g scoop. Give 1 scoop per day for dogs weighing 11-20 lbs, and 2 scoops per day for dogs weighing 21-35 lbs.

      Caution: S. boulardii can cause constipation in some dogs. Discontinue use if your dog's stool becomes hard and dry.
