Digestive Supplements for Horses
Digestive supplements for horses may contain probiotics, prebiotics, mannan oligosaccharides, sources of soluble fiber, or a combination of these ingredients.
  • Probiotics are live microorganisms, including bacteria (e.g. Lactobacillus species) and yeast (e.g. Saccharomyces species), which, when given in sufficient amounts may benefit the horse.
  • Prebiotics are non-digestible food ingredients that produce health benefits by promoting the growth of "good" bacteria in the intestine. These include oligosaccharides.
  • Psyllium is an 80% water-soluble fiber that is used to move sand through a horse's digestive system.

Digestive aids may help after worming, with horses on antibiotics, and with older horses.
