Probiotics can be defined as living microorganisms, that when ingested in certain numbers, confer health benefits beyond that of their inherent nutritional value. The microbes used in our probiotics are live non‐pathogenic organisms, such as various Bifidobacterium and Lactobacillus species, Enterococcus faecium, and non‐bacterial organisms such as the non‐pathogenic yeast Saccharomyces boulardii. Our probiotic formula is custom formulated by our veterinarian who recommends using a broad spectrum probiotic to bring balance to the gut microbiome. Each strain in our probiotic powder is proven to be beneficial for both cats and dogs and handpicked by our veterinarian. We also include prebiotics, which are non-digestible carbohydrates that modulate the intestinal microbiota and promote the growth of beneficial microorganisms in the intestines, which many other probiotics do not include.
