Vetsense Gastrosyl is a liquid digestive aid for horses and dogs dealing with gastroenteritis, diarrhoea and general gut upset. The 5-litre size is aimed at equine use and multi-animal households or clinics, where a smaller pack wouldn't last through a treatment course.

The formulation combines salicylate for anti-inflammatory pain relief with gut-protecting and binding agents that help firm stools and calm inflamed intestinal lining. It's a non-antibiotic treatment, so it won't disrupt the gut microbiome and can be used alongside prescribed antibiotics if a vet has recommended them. It addresses the symptoms — discomfort, loose stools, inflammation — while the underlying cause resolves.

Owners and stable managers keep Gastrosyl on hand as a first-line response to dietary or stress-related digestive upsets, particularly in horses where waiting for a vet visit isn't always practical. The large volume suits repeat dosing over several days.
