Designed to pass through the stomach and small intestine completely intact, FOSSENCE® arrives in the large intestine, where it acts as a selective fuel source for beneficial gut bacteria. These bacteria ferment FOSSENCE® into Short Chain Fatty Acids (SCFAs), while simultaneously increasing their relative abundance in the gut.
A thriving colony of beneficial bacteria forms a powerful defense against pathogens like Clostridium perfringens and Escherichia coli—two of the most common causes of diarrhea in dogs and cats. SCFAs also serve as an energy source for colonocytes, reduce gut inflammation, and boost immune cell activity, linking gut health directly to the animal’s broader wellbeing.
FOS is one of the most thoroughly researched prebiotic fiber ingredients available for pet nutrition.
FOSSENCE®’s high solubility, temperature stability, and clean-label credentials make it one of the most practical prebiotic fibers for pet food and supplements. From everyday dry kibble to functional treats, it integrates seamlessly into existing formulations without compromising palatability or processability.
