I am so happy for this product. My cat was dealing with diarrhea for almost a year. When I started using this product it took a few days but it is so nice not having to clean up the stinky diarrhea everyday!!!!

Lactobacillus reuteri KU-LR01 (feline-origin) helps support a balanced gut microbiome and everyday digestive comfort.

L. reuteri strains are often used for gut-barrier support and healthy immune signaling in the gut, which is where a lot of immune activity lives.

Pediococcus acidilactici KU-PA01 (feline-origin) helps support a balanced gut microbiome and digestive comfort.

Bifidobacterium animalis subsp. lactis helps support healthy gut bacteria balance and stool quality.

Saccharomyces boulardii is a beneficial yeast that helps support digestive stability, especially during times of stress or change.

Fructo-oligosaccharides (FOS) are prebiotics that help feed beneficial bacteria so they can thrive.

Mannan-oligosaccharides (MOS) are prebiotics that help support a healthy gut environment and microbiome balance.

1,3/1,6 beta-glucans (yeast) help support healthy immune response and immune signaling.

Heat-treated Lactobacillus fermentate is a postbiotic style ingredient that helps support the gut barrier and overall gut comfort.

ResiliBiome is designed for synergy, meaning each ingredient supports the others. The probiotic strains Lactobacillus reuteri KU-LR01 (feline-origin), Lacticaseibacillus paracasei KU-LP01 (feline-origin), Pediococcus acidilactici KU-PA01 (feline-origin), and Bifidobacterium animalis subsp. lactis are included to support a balanced gut microbiome. Saccharomyces boulardii adds a beneficial yeast to complement the bacterial probiotics. FOS and MOS act as prebiotics to help nourish beneficial microbes. Yeast 1,3/1,6 beta-glucans support healthy immune function, and the heat-treated Lactobacillus fermentate provides postbiotic-style support for overall gut and immune health. Together, this synergy supports daily gut + immune health more consistently than any single ingredient on its own.
