Your horse’s stomach secretes acid continuously, so they need support all day and night – not just at feeding times. The Constant Comfort® Block is designed to help soothe and support your horse’s stomach 24/7 when offered free-choice. It contains Seaweed Derived Calcium to maintain proper stomach pH, as well as Equi-Ferm XL®, a pre- and probiotic that supports hindgut pH, overall digestive health and total diet digestibility. We recommend using the Constant Comfort® Block in conjunction with Constant Comfort® Plus and Constant Comfort® Paste!
