PRO G.I. Optimum nutritional support for the health of the entire equine Gastro Intestinal tract.



Pro G.I.

Optimum nutritional support for the health of the entire equine Gastro Intestinal tract.

Pro G.I. is a high specification Gut balancer that supports the entire digestive tract. It helps maintain normal healthy intestinal mucosa, gut microflora & correct pH balance.

Pro G.I is manufactured in a UFAS (Universal Feed Assurance Scheme), BETA NOPS (Naturally Occurring Prohibited Substances), FEMAS (Feed Materials Assurance Scheme), ISO 22000 ( Food Safety Management System) certified state-of-the-art premix manufacturing facility.  Pro G.I is produced using the highest quality feed assured ingredients under strictly controlled production conditions and conforms to the requirements of EU and UK legislation governing the manufacture of animal feeding stuffs.

Pro G.I. contains:

  • Lecithin: A source of phospholipids, which support the health of the stomach lining at the cellular membrane level, nourishing the cell membranes of the digestive tract and helping protect the stomach from the damaging effects of excess acid. Lecithin can also help reduce levels of excitability and anxiety associated with digestive distress.
  • Pectin:  Forms a gel which helps support the delicate gastric mucosal lining of the stomach.
  • Beta Glucans (derived from yeast): Feeding Beta Glucans can help counteract pathogenic microbes, moderate the release of sugars from the digestive system in the bloodstream and help boost immunity.
  • ACIDBUF (Calcareous marine Algae)A Gentle Slow releasing buffering agent to help in the prevention & solution of acidosis problems in horses & ponies. Has a longer buffering action than limestone flour or sodium bicarbonate.
  • Fructo-oligosaccharides (FOS) FOS works by providing the beneficial microbes in the horse’s gut with a source of energy, allowing them to reproduce and increase their population, which results in less opportunity for bad bacteria to thrive. Research has shown that bacteria such as E. coli and Clostridium perfringens, cannot utilise FOS which means that FOS is only available to beneficial species of gut microbes.
  • Mannanoligosaccharides (MOS) MOS selectively binds to bad bacteria such as E. coli and Salmonella. The bad bacteria bind to MOS, rather than binding to the wall of the intestine and then are safely excreted in the manure.  In doing so, it reduces the pathogens from potentially causing damage to the horses digestive tract
  • Vistacell: A live yeast product of the Saccharomyces cerevisiae variety. VistaCell supports healthy gut microflora and helps maintain correct pH balance.

    This supplement has transformed my horse Louie. All bloating has gone, head shaking stopped, generally happier and at 25 he looks absolutely fantastic on it. Thank you Mel, another brilliant product.

    One of my horses often gets diarrhoea when he changes fields or hay, and I found that feeding him PRO GI around the change really alleviated the problem. I gave it to all of my horses when they first moved from winter to summer grazing, and there were firm poos all round, none of the usual cow pats!

    Since putting my mare on Pro GI she has stopped being mareish. She seems more comfortable in herself. She is quieter in her stable and in the trailer. She travels to competitions a lot so this product is great! Recommend for any horse that seems to be unsettled, have an upset tummy and/ or travel a lot. Really keeps your horse happy from the inside out!! Love this product

    We can hardly believe the change Pro G.I. has made to our stressy dressage horse; from being a grumpy boy who bucked into canter, he is now going so well. His collected canter has come on leaps and bounds and he is now scoring 70% plus at elementary, aiming for medium by the end of the year which we would not have thought possible before we tried Pro G.I. We would highly recommend this product!
