Buying Guide

Match supplement to the problem

Choose formulations targeted to the specific issue—psyllium-based products for sand removal, buffering/ulcer-support blends for gastric health, and caloric/omega-3 formulas for senior weight gain

Check active ingredients

Look for clinically relevant ingredients such as psyllium for sand, pre/probiotics for microbial balance, anti-inflammatory agents for recovery, and digestible calorie sources for weight support

Consider form and administration

Pellets, powders, and pelleted mixes differ in ease of dosing, palatability, and dust exposure; pick the form that fits your horse’s acceptance and your feeding routine

Review product ratings and value

Use verified consumer ratings and value scores to assess overall satisfaction and cost-effectiveness within the under-(price varies) category

Consult your veterinarian

Have a vet evaluate ongoing digestive signs or before starting supplements for ulcers, chronic weight loss, or recurrent colic to ensure safe, coordinated care
