Question: My horse is being treated for a mild case of ulcers. Recently read there are supplements that help with supporting good fit health after medications ...omeprazole. Can you recommend a good supplements for gut support? My horse also has EMS. Thank you. Dr. Kellon: I would suggest trying Uckele G.U.T.  The ingredients work as follows.  Hydrolyzed collagen can help by both providing a soothing coat to ulcers and ideal levels of amino acids to repair connective tissue. Deglycyrrhized Licorice has been shown to reduce risk of gastric ulcers, even with administration of nonsteroidal antiinflammatory drugs. Marshmallow root, Slippery Elm and Aloe Vera further soothe irritated gastric linings and do double duty as prebiotics that support function of the hind gut, as do mannanoligosaccharides. Saccharomyces yeast and key bacterial probiotic strains keep all levels of the digestive tract functioning normally.
