Montmorillonite Digestive Health Supplements

Diarsanyl is a nutritional supplement for dogs, calves, and foals that supports long-term intestinal and digestive health. Diarsanyl contains montmorillonite which helps manage diarrhea by combining with mucus on the intestinal mucosa.

Diarsanyl adheres to the intestinal mucosa to soothe irritation and prevent fluid loss. The active ingredient in Diarsanyl, montmorillonite, is more effective than kaolin at absorbing toxins to minimize gastrointestinal upset. Diarsanyl also contains glycerol and dextrose for energy.

Benefits of Diarsanyl:

  • Controls digestive upset and diarrhea
  • Available in a ready-to-use-syringe
  • Coats the intestinal mucosa
  • Paste is more effective than powder or pills
  • Helps maintain electrolyte levels
  • Prevents dehydration
  • Palatable oral paste in vanilla flavor
  • Replenishes the mucus layer
