Which digestive and gut health supplement is best for my horse?

Digestive EQ and RP are both complete digestive supplements for horses, targeting the entire digestive tract, from the stomach to the hind gut. They are both scientifically formulated equine gut supplements, which were designed in collaboration with equine nutritionists and vets to support enhanced performance and overall health in horses. But they are not the same.

Our high performance gut health supplements support your horses to deliver their best, feel comfortable, and thrive from the inside-out.

Great gut health is the foundation for performance

With a healthy gut, our horses can benefit from more effective digestion, reducing wasted feed and improving the horse’s condition. Great gut health supports strong immunity, as 70% of your horse’s immune system is in their gut. And of course your horse will feel better, stronger and have more energy – which allows them to exhibit calmer, trainable behaviour and to perform at their highest level plus improved recovery.

When the gut microbiome is altered, a horse’s performance is impacted. Less beneficial bacteria in the gut means less energy supply to the horse’s muscles, which impacts speed and stamina, and slows recovery.

Meet Digestive EQ

With an impressive track record of proven results since its creation in 2017, Digestive EQ is trusted by vets, equine nutritionists and thousands of horse owners to provide effective support for horses’ digestion, fore and hind gut health, and immune systems. The Digestive EQ supplement formulation has been updated and improved in the last year, and horses now get the benefit of extra buffers, an updated magnesium to calcium ratio and post biotics as well as prebiotics.

Introducing Digestive RP

This premium equine gut health product has an enhanced formulation to provide extra digestive support and gut health benefits to meet the needs of high performance sport horses and racehorses, delivering all the goodness of Digestive EQ, with the extra benefits of:

  • an additional amino acid, Leucine, known for muscle building and recovery
  • more amino acids per dose
  • an additional enzyme, Phytase, to further support efficient digestion and absorption of nutrients
  • a higher level of the Carbohydrase enzymes in Digestive EQ, to provide extra support for digestion of grain
  • A higher level of our dual action acid buffers for extra gut protection.

What does this mean?

If your horse competes at a high level, or has more grain in their diet, consider the enhanced Digestive RP gut supplement with additional amino acids and digestive enzymes, plus higher levels of postbiotics and buffers for even more gut support.

Why do high performance horses need a higher level of gut support?

Regular intense exercise, time off feed, travel and competition all impact on a horse’s gut which then in turn impacts on performance and recovery. Emptying of the stomach, increased stomach acidity and a shift in hindgut microbial populations plus a post-exercise fall in glutamine all contribute to increased risk of ulcers and ‘leaky gut’ and less energy for speed and stamina.

Why do horses who eat more grain benefit from extra gut support?

Diets high in uncooked grain are difficult for horses to digest, and undigested starch  can end up in the hindgut, creating an acidic hindgut which will kill beneficial gut bacteria, altering the gut microbiome and contribute to create leaky gut.
