GastroPremier® offers horse owners, trainers and veterinarians an opportunity to nutritionally & naturally support the health of the complete gastric, colonic and digestive systems.

A unique high quality veterinary-grade feed supplement. Efficient, effective and very powerful, works rapidly to support the gastric system, with results that can be seen in as little as 7 days.

GastroPremier® nutritionally supports healthy digestion and helps with the complete gastric system. A carefully formulated gastric supplement with a very different approach than most other products on the market due to the Nitric Oxide Pathways.

GastroPremier® supplies active nutrients, utilises Nitric Oxide precursors so the body is aware of what needs to be targeted. GastroPremier® works with the natural production of mucus in the lining of the gastric system, therefore acting as a liner and maintaining the stomach’s natural acidity levels. It does not interfere with the acid production required for healthy digestion in the hindgut.

Supports the Stomach, foregut, and hindgut. Great for the gut flora.

A successful option in the racing industry

Contains no fillers, binders or any known prohibited substances and is competition safe.

Customer Reviews

  1. I’m so glad I gave this a go, my horse has been treated for ulcers and after improving on the medication he became bloated and still a bit sensitive of his stomach once he’d come off the medication. I gave this a go after doing a lot of research and I can’t believe how much of an improvement I saw, his bloating has gone and he’s not sensitive of his stomach anymore – even when he’s eaten too much lush grass! I’d tried so many of the popular gastro supplements so i’m just really relieved to find one that works for him! And their customer service has been brilliant xx


  2. All I can say is WOW!
    Never in a million years did I think a gut supplement could make such a huge difference. I once had a very stressful up tight horse. Since using the gastro premier I’ve noticed a huge difference. My boy is now relaxed and doesn’t give a care in the world when I go to tack him up, put rugs on or do anything with! He is easier to ride under saddle too! This product is worth every penny and more!
    I can’t thank camilla enough for giving me so much advice when I saw her at Windsor. Gastro premier will now be a stable product in rufus’s feed forever more as it ultimately makes him the happy horse he is now!
    Thank you premier performance ⭐️⭐️

  3. I brought this product at the weekend and I really am amazed by it, I brought it at a camp after chatting to premier performance about some issues I have been having one of the issues being how sloppy his droppings were on the travelling to the venue I decided to put him on gastro premier, after just a couple of days on this supplement the journey home was so much better and his droppings were not sloppy at all.

    I would highly recommend this product to anyone it’s well worth the money and looking forward to seeing what other differences it makes to my horse, I also like the fact that after speaking to them they have advised after 30 days to switch to the maintenance supplement it’s not often a company would recommend you go for the cheaper supplement they really have the horses at the centre and core of what they do 🙂
