Product Description

TuffRock Gastro Intestinal (G.I.)

IMPROVED FORMULA of our already incredibly successful TuffRock GI. 

TuffRock GI is a unique digestive health liquid that's patented and made from 100% Australian Ancient Volcanic Tuff. It includes 10 essential minerals that are specially processed to be easily absorbed by the body (colloidal & chelated), ensuring optimal gut health. This special blend is designed to naturally support the digestive system's 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 weight
  • 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

    Horses love it

    Posted by Tamara Cook on 10th Jul 2024

    My horses love this stuff! It's very cold here atm, and we haven't been out a lot, but I am looking forward to taking them out knowing that their stomachs are being looked after. The mixture is quite thick in the bottle but I have just added a bit of hot water to get the last of it out. Their coats are shiny and they are looking really, REALLY good! Will be purchasing more.

    My horses can't live without it

    Posted by Rochelle King Andrews on 12th Feb 2024

    Our competition horses have been produced on TuffRock GI week after week, month after month, year after year with solid results. I always feel I must give our horses the very best possible care. They work so hard and there is nothing they won't give me, so soothing their competition gut with a large dose of GI and as a daily treatment I feel I am taking care of them like they take care of me. It is a must for every serious competition horse

    Product review

    I’ve been using the GI for over 6 years now and have used it on a variety of horses from dressage, pony club, sporting, barrel racing and now rope horses and I can truly say it has made the world of difference. Their coats are super shiny, they are maintaining their weight much easier, looking super healthy and I haven’t had near as much trouble with gastrointestinal issues whilst my horses are on this product. I highly recommend it. It is a staple in our feed room.

    I have been a long time user of TuffRock products and I'm a huge believer in them. I have all of my horses young and old on this product and I believe it is one of the best supplements on the market. My horses look the picture of health and are glowing. Their coats are rich in colour, super shiny and they hold their weight really well when on this product. I also haven't had any issues with ulcers since starting my ulcer prone horses on it. G.I works from the inside out to ensure your horses are feeling their best which keeps them at the top of their game. Highly recommend.

    love Tuffrock GI

    Posted by Kylie Hutcheon on 12th Feb 2024

    Within a fortnight my gelding went from refusing to eat due to ulcers to stacking on the weight and scoffing down his food after dosing with Tuffrock GI. We often recommend TRGI to clients with suspected ulcers. Fantastic product and service!!

    a must have

    Posted by sally j on 12th Feb 2024

    We have been using tuffrock for many years since it first came out and this is the product that is a must have for any horse person. There have been many times that gi has saved a vet call out but the biggest testimonial would be when we had a horse with collitis. Tuffrock gi kept her going for an hour until the vet arrived and then for the 3hr trip to a specialist vet hospital. She was able to walk off the truck much to the shock of the vets based on her obs.

    Absolutely amazing results in performance horses!

    Posted by michelle shields on 12th Feb 2024

    GI formula speaks for itself! Horses in full work pick up in no time - especially out here in very hot conditions where they can become lethargic & exhausted- just like humans do! They really pick up on it, coats get so so shiny and older horses are clearly experiencing less pain. Awesome product!!
