Buying Guide

Check active ingredients

Look for clinical or commonly recommended ingredients for equine gastric health such as specific probiotic strains, prebiotics, buffering agents (e.g., kaolin, saccharomyces, clay-based buffers), and digestive enzymes

Match formulation to need

Choose powders or pellets based on whether you need daily microbiome support, ulcer relief, or stress-related digestive calming—some formulas emphasize buffering and ulcer relief while others focus on probiotics and enzymes

Consider dosing convenience

Pellets and ready-mix formulas are easier for herd management and consistent daily dosing, whereas powders may allow more precise dose adjustments for individual horses

Evaluate multi-purpose benefits

Supplements that combine probiotic strains with prebiotics, digestive enzymes, and calming or anti-ulcer components can address multiple digestive concerns in one product

Compare cost-per-dose

Assess value by comparing servings per container and recommended daily dose to estimate cost per day and find options that fit budget and long-term use
