GastroPLUS nutritionally supports healthy digestion and gastric issues. Other gastric products decrease the acid in your horse's stomach, which can lead to protein entropy. When a horse is taken off of the other gastric products, it may relapse because the body over compensates and produces too much acid, turning it into a vicious cycle of gastric problems. GastroPLUS helps your horse's own ability to produce more mucus in the stomach lining, therefore helping your horse control and contain the acid. This helps address hind gut issues, in a more effective and efficient way. Dosing Instructions: Per 1,000 lb horse, as a top dress to the feed, give 1 level scoop per day.
