Gastric Supplements for Horses
View a list of the best gastric supplements for horses in Mad Barn’s equine feed database. Gastric supplements are digestive support products that act through several mechanisms to maintain a healthy stomach environment: maintaining the protective mucus layer and the integrity of the stomach lining, supplying amino acids that serve as substrates for epithelial cell turnover and mucin production, supporting microbial balance, or buffering excess stomach acid.
Equine gastric supplements may contain ingredients such as lecithin, marshmallow root, slippery elm, glutamine and threonine, magnesium, probiotics, prebiotics, and antioxidant botanicals that support the gastric mucosa, digestive function, and normal function of the stomach and hindgut. They are often chosen for horses exposed to common risk factors for gastric ulcers – including intense training, travel, stress, stall confinement, and high-grain, low-forage diets. Compare active ingredients, feeding directions, cost per serving, and nutritional profiles to find a supplement that fits your horse’s needs.
