Are You Looking To Optimise Your Horse’s Health And Performance?

High performance horses face higher gut health risks because of confinement, travel, heat stress, and of course, intense exercise.

These may lead to concerns such as:

Anxious Behavior
Dull Coat
Weight Loss
Colic
Loose Manure
Brittle Hooves

To support your horse's overall well-being and performance, consider incorporating Digestive HP, our foundation gut health supplement that is essential for all high performance horses.

Here Are The Changes You May See In Your Horse

Digestive HP is a total digestive tract equine gut supplement, designed to meet the needs of high performance horses.

It contains high-level post-biotics and enzymes for digestion as well as amino acids for muscle recovery and gut support.

When you want your horse to look, behave, perform and recover at their best, try Digestive HP.

A gut in distress causes discomfort, especially around the area of the large colon near the girth.

Supporting gut health reduces discomfort, and helps tolerance to girth pressure.

Encouraging a more stable gut environment decreases anxiety.

Supporting hindgut bacteria also enhances the production of calming B vitamins and hormones, plus increased muscle energy through fiber fermentation.

Because the hindgut sits on the right side of the horse, any pressure on this when the hindgut is agitated will cause discomfort for your horse.

This makes movements like the lifting of the back in the right canter transition, the left to right flying change, or the right canter pirouette difficult as the lack of bend and lift prevents the right hind leg reaching through under the horse to take the weight.

When your horse's hindgut is healthy, these movements become easier.

Through balanced electrolyte ratios, and an increase in the functional gut surface area, enzymes in Digestive HP enhance normal digestive function, enabling optimum feeding while supporting healthy hindgut bacteria and efficient fiber digestion.

The decrease in cortisol production from reduced stress associated with a healthy gut leads to the building of a stronger skin barrier, and a more robust hair fiber quality.

Here’s Why Veterinarians Love Digestive HP Designed by veterinarians, nutritionists and microbiologists, Digestive HP represents an unmatched commitment to equine health.

“As a veterinarian, and having competing myself in show jumping at an elite level for many years, I recommend Digestive HP to many of my clients.

I have seen improved performance, recovery, and overall health through a stronger and more resilient GI Tract.

It is so important to know that these horses are receiving support and protection from the stresses of daily training and frequent competition.

So for great performance and swifter recovery in any elite equine athlete, Digestive HP is my go to choice.”

Dr. Erin Roddy Veterinarian and Show Jumper

"Digestive HP takes it to the next level with its formulation.

It's designed to assist with peak condition, helping to recover faster from high intensity work, as well as supporting through high stress that comes with being a high performance horse."

“I Would Not Go Without Digestive HP”

As a grand prix professional dressage rider, I ask a lot of my horses. The stress of regular competition and travelling, along with an intense exercise program and at times extreme weather conditions can all have a big impact on the health, performance and recovery of my horses.

Having seen the results first hand, and how they look and perform on these, I honestly would not go without Digestive HP and Stress Paste.

David McKinnon Grand Prix Dressage Rider
“The Transformation Has Been Remarkable”

My future Grand Prix horse, Apple-Bee, faced significant challenges arriving in Ocala from Belgium, like environment change, competition, heat, and frequent travel. She battled poor appetite, inconsistent energy, and required ulcer treatment.

However, since incorporating Digestive HP and Stress Paste into her routine, her appetite and energy levels have become consistent, even during competitions.

Notably, she is no longer on ulcer treatment, her topline has improved, and her recovery after intense exercise has been exceptional.

I highly recommend Digestive HP and Stress Paste to anyone seeking to enhance their horse's ability to cope with the demands of competition and perform at their best.

Maleah Lang-McMahon International Show Jumper, Australian Representative to FEI Youth Equestrian Games
“Digestive HP Has Been The Saving Grace For My QH”

I have found Digestive HP to be the saving grace for my QH. Nearly 4 yrs out of work with a sore back and cranky and unable to even touch his stomach, which was particularly bad on the right side as he pinned ears back and gave warning bites and intermittent temps of 42. I tried 3 different vets, had all the blood and urine tests, ultrasound, x rays, abdominal taps and not one vet could find how to help him. 

We are now about to start his 3rd bucket of Digestive HP and he's back in light work being led by my other horse doing 10kms a day and no more pain! He's happy and back to his normal self. I am so grateful for this product and the advice given to me by them.

"I've Been Using Digestive HP For Years"

I have been using Digestive HP for several years.

With our intense competition schedule and travel requirements it gives me peace of mind knowing that my horses have the digestive support they need for optimal health and performance.

"This Saves My Clients And I Time And Money"

Holly has transformed over a month with the help of Digestive HP.

Her physical attributes, trainability and calmness under saddle has developed enormously.

As a trainer, this is game changing, saving my clients and I time and money.

Why Digestive HP?

Did you know that your horse’s gut houses 70% of his immune system? 

So if your horse is struggling with occasional soft manure, poor digestion, body condition, poor performance and recovery, poor behavior and even lack-lustre hoof health and dull coat condition, it’s likely that the trillion of microbiomes in his gut are overworked and need help.

Targets The Whole Of The Gut Most supplements target one area of the gut. The proprietary blend of postbiotics, digestive enzymes and amino acids in Digestive HP work from the foregut to the hindgut and through the 21 meter long intestine too!
Improved Performance & Recovery A healthy gut means horses can benefit from more effective digestion, reducing wasted feed, and better condition. Your horse will feel and look better, with trainable energy and behavior to perform at their highest level with improved recovery.
Recommended By Veterinarians We’ve collaborated with experts in their fields to develop a science-backed, nature-based gut health supplement that is recommended and endorsed by veterinarians, nutritionists and microbiologists.
Manufactured in the USA We take pride in where we source and how we make our products, and only use the highest quality ingredients.

Frequently Asked Questions Gut health can be confusing. Our team of experts are here to help you get the best information for you and your horse.

Digestive HP is a complete gut health supplement, designed to maintain and strengthen great gut health for all horses, and especially high performance horses.

Benefits from great gut health are:

  • Healthier appearance
  • Happier, easier behavior
  • Stronger appetite
  • Better performance
  • Faster recovery

Horses can not and will not perform to their full potential if things in their gut aren’t right.

The reduced hormone and vitamin production, reduced appetite, feed digestion and supply of energy, leaky gut, and compromised immune function that occur when gut health is compromised all contribute to horses having poor performance.

And research continues to show us how certain disease states, anxiety and hyperactive behavior that reduces rider safety and horse welfare are all linked to gut health.

By feeding in a way that supports gut health, we are able to support a horse’s mental and physical wellbeing, behavior and performance!

Digestive HP contains:

  • A Pre and Postbiotic Blend; TruEquine ™ yeast culture that has been proven to:
  • Support the hindgut fiber fermenting bacteria, to increase the amount of muscle energy they are able to produce via fiber fermentation.
  • Reduce whole-body stress, with horses supplemented having lower serum cortisol and lower serum amyloid A (SAA) after exercise; and
  • Support joint health, with supplemented horses having lower Prostaglandin E2 (a biomarker used to assess inflammation) in their joints following exercise.
  • Balanced Calcium to Magnesium Ratio is necessary to assist with bone health, nervous system function and behavior .
  • Two acid buffers; Marine Algae Calcium and Magnesium Hydroxide, to help maintain a normal stomach PH.
  • Essential Amino Acids.  L-Threonine, L-Glutamine, L-Proline, L-Serine and L-Leucine are designed to improve mucous production and reinforce gut wall support to reduce susceptibility to injury.
  • Digestive Enzymes. Xylanase, Beta-glucanase, and Cellulase to enhance the digestion of starch in the small intestine and maximise muscle energy provided as glucose/glycogen.
  • Phytase Enzymes to help break down phytate preventing it from negatively impacting the digestion and absorption of other important nutrients.
  • Mycotoxin Binder;Elitox ETX-5TM, to reduce the harmful and frequently undiagnosed impact of fungal mycotoxins commonly present in hay, chaff and grains.

Whilst you may see similar benefit's with these products, their intended usage is what makes Digestive HP and Stress Paste fundamentally different.

Digestive HP is the every day gut-health supplement that supports your high performance horse through their day-to-day stressors, to keep them performing at their best.

Available in both 10lb and 40lb sizing, the powdered form makes it ideal to include twice daily in standard feeding routines.

Stress Paste plays best in instances of acute stress, designed to deliver immediate gut and nervous system support in the face of high impact events including competition, travel and extreme weather.

Conveniently formulated in a concentrated paste, Stress Paste is easy to give within 2 hours of a known or predicted stressful event, rather than fed as daily maintenance where Digestive HP is the product of choice!

Horse owners who are using Digestive HP are reporting seeing improved changes in as early as 1 week, with horses appearing calmer and more settled.  

Another noticeable improvement is in the consistency of manure. Some horses that have been scouring for months have reportedly formed solid manure within days of using our digestive gut supplement.

In as little as two weeks, horse owners are beginning to see improved top line and condition, particularly noticing filling out above the flanks around the loin area.

After 3-4 weeks people are consistently noticing significant behavioral, performance, and recovery improvements, as well as a noted improved suppleness under saddle and putting on weight.

If you don’t see a result that quickly, don’t panic. Every horse is different with some taking longer to respond due to repopulation of healthy microbes, particularly in their hindgut. If your horse doesn’t have obvious outward symptoms of gastrointestinal upset, positive changes are going to be less obvious but can be as subtle as improved hoof growth and increased immunity.

But remember, seeing the results is just the start. Supporting optimal digestion and the health of your horse’s gastrointestinal tract longer term with the correct diet in combination with Digestive HP will ensure optimal health and performance into the future.

As part of our research and design phase of our digestive gut health supplement, we undertook a trial with numerous horses across various disciplines. The results were overwhelming with consistent reporting of improved condition, topline, behavior, manure consistency, performance, appearance and the ability to cope with stress.

We also undertook a field study with a further cohort of randomly selected horses with Professor Andrew Dart (BVsc PHD,Dip ACVS, Dip ECVS) in an attempt to measure observable outcomes.

Every single horse in the study showed a remarkable increase in feed conversion with some horses increasing their weekly weight gain by up to 9 times.

“It is difficult to dismiss the relationship between weight gain and the addition of this supplement” commented Prof Dart.

Additionally, the hundreds of testimonials speak for themselves.

Yes it is. Like everything with Laminitic horses, introduce it slowly, just to be on the safe side. Laminitics can be unpredictable, so slow is always best when adding something new to their diet.

Digestive HP is not designed to treat existing gastric ulcers. Please consult your veterinarian about treatment with a registered gastric ulcer medication if your horse has confirmed ulcers. The veterinarian should be able to properly diagnose stomach ulcers via a gastroscopy and determine if your horse requires treatment with a prescription medication. 

Once your horse has been diagnosed and commenced  treatment for ulcers, Digestive HP can be used (alone or in conjunction with the treatment).

Yes, Digestive HP can be safely fed to pregnant and lactating mares to support their gut health and potentially also their milk production. It should be fine for foals to nibble on a bit of their mother's feed containing Digestive HP. However, as there aren't studies specifically aimed at foals for a majority of the ingredients, we can't recommend giving it as part of a foal's feed. 


As Digestive HP includes ingredients specifically designed to address gut health, it should be safe to feed alongside most other feeds and supplements. You may find that with the addition of Digestive HP and a balanced diet with vitamins and minerals, your horse may not need additional supplements. For example, Digestive HP contains a good amount of calcium, magnesium and a toxin binder, so if you are already feeding another supplement with those in it, you may find you can cut it out. No need to waste money on over-supplementing.


Please note that our supplements are not complete feeds and should be paired with a balanced diet and adequate amounts of forage.

I suggest you run your horse's current diet through our free, online Diet Calculator, Feed Assist. This useful tool will suggest which, if any, other supplements your horse may be lacking. A more comprehensive and detailed calculator is FeedXL, however this is a pay to use service.

Power Your Horse’s Performance From Within

Most supplements target one area of the gut. Digestive HP is multi-faceted, highly efficient, with a blend of pre and postbiotics, digestive enzymes and amino acids - that works all the way through the foregut, hindgut and intestine.
