Gastroade® is a calcium and magnesium supplement that helps to promote a healthy digestive system. Poor appetite, dull haircoat, mild to severe colic, changes in mood, and a drop in performance levels are all signs of a horse with gastric distress. Gastroade contains aloe vera and kaolin that work together as a buffer to help soothe and coat the horse’s stomach lining, thus reducing gastric distress. Recommended Dosage: 3 oz. twice daily.
