Product Description

TuffRock G.I.

IMPROVED FORMULA of our already incredibly successful TuffRock GI. 
TuffRock GI is a patented gastro-intestinal liquid made from 100% Australian ancient volcanic tuff with 10 Essential Minerals colloidal chelated for gut health. 

It binds and reduces the effects of harmful mycotoxins in the diet, and assists to maintain normal gastro-intestinal function, pH levels and gut flora when used regularly.

GI is also suitable for use during:
- gastro-intestinal upset

- times of stress
- travel
- change of feed
50ml per 500kg horse. Use pre-feed morning and evening for 10 days. Repeat for a further 10 days if necessary.
Maintenance - 20ml once daily in feed. 
Shake well before use. Store out of direct sunlight and do not freeze. 
If formula becomes too thick, add one tablespoon of warm water and shake. Continue to add one tablespoon at a time if necessary to restore to original consistency.

    After a recommendation, we tried G.I. gastrointestinal liquid and sure enough after the loading period we began to see shinny, neat - and somewhat firm - balls of manure! We are so excited that our mare now has her $#*% together! Yahoo!

    This is a superb product that is essential in my stables, I use it everyday for the horses in training, I give in large doses every few hours if any of the horses are slightly off their feed and I give it to foals twice daily from birth til a few weeks old to keep them safe from constipation and to smooth the way to life. TuffRock GI is gold

    I used the GI liquid on my 19 year old thoroughbred who refuses to get on the float because of stress and because he spooks at cars when we go for trail rides but now he self loads and just plods along! This is an amazing product for your horses. I 100% recommend this

    Wonderful product, Recently needed to have my Horse transported to Queensland. I made up 10 feeds AM/PM just chaff and poured GI on top. Certainly helped his gut whilst travelling for many days. G.I forms part of my daily routine. They love the taste .Highly recommend.

    Fantastic for travelling Performance Horses

    Tuffrock GI has been great for one of my top performance horse! It has helped him not stress after the long travel and keep him happy and healthy when he is competing! Helps him deal with the new environments and stables he often finds himself in. Tuff Rock GI would have to be one of my favourite products to use especially when I’m at events!

    miracle product

    After purchasing my OTTB I could literally not find any product on the market that would stop his stools from being runny even after vet consoltations. This issue went on for W while even after thousands of dollars spent on vet examinations. Fortunately, I have finally found a product that works!! No more sloppy stooles! Super easy to mix in with feed and a finacianlly sustainable product that doesn’t burn a hole in your procket!
