Standard Process Launches GI Soothing Probiotic
Standard Process has introduced GI Soothing, a new probiotic supplement for dogs and cats that combines Saccharomyces boulardii with postbiotic metabolites
Standard Process has launched a new probiotic supplement for dogs and cats called GI Soothing. The company announced the product on August 25, 2026, entering a growing market for companion animal digestive health products.
The supplement is formulated to support digestive comfort, bowel function, and gastrointestinal balance. It is intended for animals experiencing occasional digestive upset, diarrhea, sensitive stomach, or stress-related digestive distress. Standard Process says GI Soothing is available for preorder and is marketed through participating veterinary professionals.
Product Formulation and Function
GI Soothing contains two primary ingredient blends. The first is a biotic blend. It pairs the probiotic Saccharomyces boulardii with postbiotic fermentation metabolites from Lactobacillus fermentum and L. delbrueckii. According to the company, these ingredients support intestinal barrier function, microbial balance, stool quality, and immune signaling.
A second blend includes the botanicals marshmallow root, slippery elm bark, and okra. Standard Process states these ingredients provide polysaccharides that swell in water to form a gel. This gel is intended to coat the gastrointestinal lining during periods of irritation.
The company emphasizes that its approach combines a probiotic with postbiotic metabolites, rather than relying solely on live microorganisms. Standard Process says this provides support without depending entirely on live microbial colonization.
Market Context and Demand
Digestive issues are a leading cause for veterinary visits. According to the North American Pet Health Insurance Association's 2026 State of the Industry Report, gastrointestinal problems were the single most common insurance claim for both dogs and cats in 2025. This high incidence drives steady demand for products aimed at supporting digestive health.
“GI Soothing is formulated to support pets during such events and is intended to give veterinarians an evidence-informed, integrative option for supporting patients experiencing occasional stomach and intestinal discomfort,” said Katrina Verdeur, MS, pet product development manager at Standard Process.
Recent Probiotic Market Entries
The launch of GI Soothing follows several other new probiotic product introductions for pets in recent months. The source report from dvm360 details three comparable products that have entered the market.

IFF's PureStrong, launched in April 2026, is a canine probiotic derived from a strain sourced from the dog microbiome. The company claims that in a controlled study of healthy dogs undergoing an abrupt diet change, dogs receiving PureStrong showed improved markers of digestive health and firmer stools without constipation.
Nestlé Purina PetCare released its FortiFlora Diarrhea Response Kit in August 2026. Similarly, Nutramax Laboratories Veterinary Sciences offers a Proviable Diarrhea Support Kit. Both products combine a kaolin-pectin binder with probiotic elements.
GI Soothing is intended for dogs and cats of all ages. The product's launch adds another option for veterinarians and pet owners seeking to manage common gastrointestinal problems.
