What Happened
Standard Process announced the launch of GI Soothing on August 25, 2026. The product combines a biotic blend featuring probiotic Saccharomyces boulardii at more than 1 billion colony-forming units per serving with postbiotic fermentation metabolites from Lactobacillus fermentum and L. delbrueckii.
A second mucilage blend contains marshmallow root, organic slippery elm bark, and okra — plant-derived ingredients that provide viscous polysaccharides forming a soothing gel to coat the gastrointestinal lining during periods of irritation.
Market Context
Digestive upset is among the most common reasons pets are brought in for veterinary care. According to the North American Pet Health Insurance Association’s 2026 State of the Industry Report, gastrointestinal issues were the single most common insurance claim for both dogs and cats in 2025.
GI Soothing enters an increasingly active market segment:
- IFF PureStrong (April 2026): Canine probiotic built around Limosilactobacillus reuteri
- Nestlé Purina FortiFlora Diarrhea Response Kit (August 2026): 2-step OTC system with kaolin-pectin binder + probiotic
- Nutramax Proviable Diarrhea Support Kit: Similar kaolin-pectin + multi-strain probiotic approach
Product Differentiation
Unlike products relying solely on live microorganisms, GI Soothing combines probiotics with postbiotic fermentation metabolites. Standard Process says this approach provides complementary support without depending solely on live microbial colonization — potentially beneficial for pets with compromised gut environments.
The formula also incorporates beet, Swiss chard, and oats grown on Standard Process’ certified organic farm in Wisconsin.
Veterinary Reception
Nicole Sheehan, DVM, reported positive field results: ‘I’ve been impressed to see that animals at our practice have been happy to take the supplement, even in the face of GI upset. Our animals seemed to improve within 1-2 days, giving us an effective, comprehensive solution.’
What This Means for the Industry
The convergence of multiple major players launching digestive health products in 2026 signals that the veterinary probiotic category is maturing from niche to mainstream. Pet owners increasingly expect evidence-informed options for common conditions, and veterinarians are gaining more tools to address the most frequent reason for clinic visits.
Key Takeaways
- GI upset remains the #1 reason for veterinary visits — creating sustained demand
- Postbiotic + probiotic combination represents next-generation formulation approach
- Multiple major launches in 2026 indicate category acceleration
- Veterinary-exclusive distribution maintains professional channel positioning
