PALMYRA, Wis., Aug. 25, 2026 (GLOBE NEWSWIRE) -- Standard Process®, a leader in whole food-based nutritional solutions, today announced GI Soothing, the newest addition to its Standard Process Veterinary line of human-quality supplements. Now available for preorder, GI Soothing combines a unique blend of probiotic (Saccharomyces boulardii), postbiotic (L. fermentum, L. delbrueckii), and soothing botanicals (Marshmallow root, organic slippery elm bark, and okra) to support digestive comfort, healthy bowel function, and gastrointestinal balance. Key ingredients also include beet, Swiss chard, and oats grown on Standard Process’ 850+ acre certified organic farm.

Digestive upset has been cited as one of the most common reasons pets need veterinary care. A 2025 review of over 1 million pets found that diarrhea and upset stomach were the most common health issues among cats and the second most common among dogs. GI Soothing’s whole food-based formula provides natural gastrointestinal support for cats and dogs experiencing:

• Occasional gastrointestinal discomfort
• Occasional diarrhea or sensitive stomach
• Nervous gut associated with temporary stress or stress-inducing events
• Increased demands on the enteric and immune systems

“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, which is very important from a practicality standpoint,” said Nicole Sheehan, DVM, CVA, CVFT, CVCH. “Our animals seemed to improve within 1-2 days, giving us an effective, comprehensive solution for such common cases that can benefit from veterinarian support.”

A Dual-Blend Approach to Gastrointestinal Support
GI Soothing features two complementary ingredient blends designed to support several aspects of gastrointestinal health:

• A Biotic Blend featuring the probiotic Saccharomyces boulardii and postbiotic Lactobacillus fermentate from L. fermentum and L. delbrueckii. Each serving contains more than 1 billion CFU of S. boulardii at the time of manufacture. Together, these ingredients help support intestinal barrier function, microbial balance, stool quality, microbial diversity, and healthy immune signaling.
• A Mucilage Blend of marshmallow root, organic slippery elm bark, and okra. These plant-derived ingredients provide viscous polysaccharides that swell when combined with water, creating a soothing gel that supports the gastrointestinal lining and promotes digestive comfort during periods of occasional irritation or instability.

Unlike formulas that rely exclusively on live microorganisms, GI Soothing includes both a probiotic and postbiotic fermentation metabolites, providing complementary support without depending solely on live microbial colonization.

GI Soothing can be used in dogs or cats of all ages. In field studies to date, puppies, which frequently experience such GI issues, have responded well to the formula.

“Gastrointestinal upset and diarrhea are common issues seen in companion animals. As pets explore their environments, they encounter a wide range of factors that can contribute to temporary digestive distress,” said Katrina Verdeur, Pet Product Development Manager at Standard Process. “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.”
