New look, same trusted Protexin Equine products.

Gut Sponge is a palatable, peppermint flavoured, nutritional supplement formulated to support hind gut health and encourage the formation of normal droppings.

Containing psyllium husks, a prebiotic and valuable energy source for the horse due to its fermentation by the microbiota, this provides safe calories, promotes the growth of friendly bacteria and nourishes the gut lining cells.

  • High fibre psyllium husks absorb water in the gut, coating and protecting the gut lining and helping the production of normal droppings
  • High level of bentonite - a natural binding agent - and source of essential minerals.
  • Linseed is a nutritious source of omega 3 and 6 fatty acids, which supports gut health and general well-being
  • Gut Sponge can be used in conjunction with Gut Balancer for probiotic support

All Protexin Equine supplements are complementary feeds - designed to provide nutrition, as well as support digestive function and efficiency.

Gut Sponge

5 stars out of a maximum of 5

So impressed by this product! My horse is very sensitive to seasonal changes and any slight change in grass/forage etc, so this product has really helped firm his droppings up as nothing else was working! I noticed a difference after the first day of using it! It seems very palatable too as he hasnt even noticed it is in his feed. Will definitely use again in the future around the time of seasonal changes/when needed. Would 100% recommend.

Does the job!

5 stars out of a maximum of 5

Our pony had previously suffered with the runs when the grass changed or when in stressful situations like travelling. A course of this alongside gut balancer and the issues have never returned, even with seasonal grass changes.  Does exactly what it said it would and better than the expensive product our vet suggested.

Amazing product

5 stars out of a maximum of 5

Whenever there is a changing in diet, grass, season or stress where the runs can occur this is honestly the best product out there. Helps within the first few days and after the 10th day can come away back to normal gut health
