According to a study published by Slovis, N. 2016; Equine gastric ulceration impacts condition, performance and behavior; the prevalence of ulcers in horses can reach 80-90% of the population. 

Looking back to a study published by Sykes, B.W. 2015; Prevention of Equine Gastric Ulcer Syndrome (EGUS) using pharmaceutical drugs with Proton pump inhibitors will "Irreversibly Impair" the proton pump. EGUS healing rates ranged between 70-77% using a daily dose of Omeprazole for 28 days.  The alarming finding for Omeprazole as a prophylactic is that 23% of horses experienced worse results.

The study by Slovis, N. 2016; concluded that horses given the "All Natural" polysaccharide blend of Hyaluronan & Beta Glucan showed that 90% had "Complete Resolution" or "Improvement" in ulceration. Improvements included morphological changes, behavior changes, weight gain and reduction of colic.
