GastroKind - Impact on Ulcer Scores and Symptoms

QUESTION: Does a Gastric Ulcer Supplement Improve Clinical and Owner Reported Symptoms in Horses with Equine Gastric Ulcer Syndrome?


  • Equine gastric ulcer syndrome (EGUS) is common in exercising horses and is further categorised as equine squamous gastric disease (ESGD) and/or equine glandular gastric disease (EGGD)1. Despite medication and changes in management, a proportion of horses suffer recurrence of EGUS.
  • A feed or supplement that could be used to aid the effective management of EGUS would be useful. GastroKind (Science Supplements) contains a combination of Vitamin E, Vitamin C, yeast powder, fruit pectin, lecithin, magnesium hydroxide and a novel (patented) fruit extract of Ficus glomerata.

Aim of Study

To investigate the effect of GastroKind on clinical and owner reported symptoms in horses with Equine Gastric Ulcer Syndrome

Study Design

  • Prospective clinical case series = a group of horses selected for a particular reason (EGUS in this study) was followed over several months following an intervention (treatment).

Study Outline

Eight horses diagnosed with EGUS grade 1- 41 by gastroscopy were enrolled in the trial. Five horses (62.5%) had ESGD whereas all 8 horses (100%) had EGGD (Table 1). Five horses with grade 1 or 2 ulceration were treated with GastroKind only. Three horses were given the recommended GastroKind dose (300ml twice daily) and two horses were given 100ml twice daily. Three horses with grade 3 or 4 ulceration were treated with oral omeprazole at standard doses (4mg/kg or 2mg/kg once daily) and GastroKind 300ml twice daily (Table 1). Horses underwent a second gastroscopic examination after approximately 4 weeks of treatment.

Study Results

  • All 8 horses with EGUS showed significant clinical improvement with either complete resolution of ulcers or reduction in ulcer score at second gastroscopy (Table 1).
  • Both ESGD and EGGD scores were significantly decreased at post-treatment gastroscopy (Figure 1). In the five cases treated with GastroKind alone, behavioral and gastroscopic improvements were observed, resulting in reduction of at least one grade of ulcer severity (Table 1).

Take Home Message

  • GastroKind supplementation resulted in improved behaviour and reduced gastroscopic ulcer scores in 5 horses with grade 1 and 2 gastric ulceration. Supplementation of Gastrokind in addition to oral omeprazole led to significant decrease in ulcer scores in 8/8 horses with EGGD ± ESGD.
